You can now use lambda expressions in the Watch, Immediate, and other debugger windows in C and Visual Basic. You can use the PerfTips feature to see how long code took to execute directly in the editor when you set breakpoints and step with the debugger.

If the debugger detects that a called function is deadlocked, it will attempt to resolve the issue. This results in a faster start for debugging. We added two new tools, the Live Visual Tree and the Live Property Explorer that inspects the visual tree of your running WPF application, as well as the properties on any element in the tree. These tools allow you to select any element in your running app and show the final, computed, and rendered properties. The tools also include the following:.

Picking apart how properties override each other and figuring out winning behavior can prove difficult at design time. You can configure debugger exception settings by using the Exception Settings tool window.

The new window is non-modal and includes improved performance, search, and filter capabilities. Our new Timeline tool provides you with a scenario-centric view of the resources that your applications consume that you can use to inspect, diagnose, and improve the performance of your WPF and Windows Store 8. The Timeline tool that is in the Performance and Diagnostics hub shows you how much time your application spends in preparing UI frames and in servicing networks and disk requests.

The tool does so in the context of scenarios such as Application Load and Page Load. We added a new Diagnostic Tools window that appears when you start debugging press F5.

The Diagnostics Tools window contains the following features:. In previous releases, the Diagnostics Tools window supported the following project types and debugging configurations:.

Just My Code. When you press F5 to launch the debugger, it will show only your code so that you can understand performance issues and exceptions without noise from framework and other code.

Because this new code filtering functionality in IntelliTrace suppresses system code and exposes only user code, it makes it easier for you to debug "just my code. Network Diagnostic Tool. This new network diagnostic tool can help you diagnose network-related issues when building Windows store apps as well as universal apps that run across all Windows 10 devices, from Windows Phone to Xbox and Windows Store.

The network diagnostic tool records information about your app's HTTP network operations, including HTTP request and response headers, request and response payloads, cookies and detailed timing information, and more.

This new view helps you derive meaningful insights, including:. For more information, see Get insights across your exploratory testing sessions. You start by specifying a shared query for work items that you are interested in and the sessions page shows a list of all the work items from the query, with a breakdown of both explored and unexplored items in the summary section.

In addition, using the "Unexplored Work Item" group by pivot, you can see the list of items that have not been explored yet. This is extremely useful to track down how many stories have not been explored or gone through a bug-bash yet.

This opens the Request feedback form where you can choose the stakeholders you want feedback from and optionally provide a simple set of instructions prompting for the areas of the product you would like input. This will send off individual mails to the selected stakeholders along with the instructions provided, if any. Additionally, stakeholders can navigate to the "Feedback requests" page to view in one place all feedback requests received by them.

From the list, they can select the feedback request they want to provide feedback on, manage their "Pending feedback requests" Figure 88 by marking them as complete or by declining them and can switch between different types of feedback requests by clicking on the desired radio button Figure In addition to the solicited flow mentioned above, stakeholders can also use the extension to provide voluntary feedback Figure Test result console logs that are captured in.

You have an option to preview them in Tests tab, and do not need to download the trx file to view logs anymore.

Widget configuration options can help you customize the chart to include pivots like passed test count, failed test count, total test count, pass percentage, and test duration.

It is a recommended practice to use Release Environments to deploy applications and run tests against them. With this release, we have integrated test pass rate of Release Environments in the Environments section of the Release summary page Figure As shown in the screenshot, if an Environment has failed, you can quickly infer if the failure is because of failing tests by looking at the Tests column.

You can click on the pass rate to navigate to the Tests tab and investigate the failing tests for that Environment. It is a common scenario for an individual test to run on multiple branches, environments, and configurations. When such a test fails, it is important to identify if the failure is contained to development branches like the main branch or if failures also impact release branches that deploy to production environments.

You can now visualize the history of a test across various branches that it is testing by looking at the History tab in Result summary page Figure Similarly, you group by the Environment pivot to visualize the history of a test across different Release Environments in which its run.

Users can now track the quality of their Requirements right on their Dashboard Figure We already have a solution for Requirements quality for our Planned testing users and we are bringing it to our users who follow Continuous Testing.

Users are able to link automated tests directly to Requirements and then use Dashboard widgets to track the quality of Requirements you are interested in tracking, pulling the Quality data from Build or Release. We have enabled tests from within an assembly to be distributed to remote machines using the Run Functional Tests task Figure In TFS , you could distribute tests only at the assembly level. This is enabled using the check box in the task as below. Users can dynamically set up test machines in the cloud with Azure, or on premises using SCVMM or VMWare, and use these machines to run their tests in a distributed manner.

You can now trigger a SonarQube analysis in the Maven and Gradle build task by checking 'Run SonarQube Analysis', and providing the endpoint, the SonarQube project name, the project key, and the version Figure You will also now get a link on the SonarQube project Figure You can request a full analysis to see the quality gates details, and choose to break the build if they are not met.

For more information, please see The Gradle build task now supports SonarQube analysis. Project collection administrators can now browse to the Visual Studio Marketplace from a Team Foundation Server and install free extensions in a team project collection. The extensions are automatically downloaded from the Visual Studio Marketplace, uploaded to the Team Foundation Server, and installed in the selected team project collection Figure Project collection administrators can now browse to the Visual Studio Marketplace from a Team Foundation Server, buy paid extensions, and install them in a selected team project collection Figure The administrator can pay for extensions with an Azure subscription and select the number of users to assign these extensions.

These extensions are automatically downloaded from the Visual Studio Marketplace, uploaded to the Team Foundation Server, and installed in the selected team project collection. For more details, see Get extensions for Team Foundation Server documentation. In , we removed this setting from the configuration experience.

If you want to continue using NTLM authentication in , you do not need to take any action. If you had been using Kerberos authentication and want to continue doing so in , you do not need to take any action.

With this configuration, Kerberos authentication is used where possible, providing enhanced security. We did extensive testing to ensure that there would not be any impact on existing TFS deployments using NTLM authentication due to this change. In this release, we are enabling a new and improved top navigation bar. There are two core goals for the new nav:. Since this is a big change for our users, and the feature is still being iterated on, we decided to have the new navigation UX off by default.

If you want to play with it, you can enable it by going to the Team Foundation Server admin area Control Panel and choosing to "Turn on new navigation". Please note that it enables it for all users in the server. The permission controlling which users can rename a team project has changed. Previously, users with Edit project-level information permission for a team project could rename it.

Now users can be granted or denied the ability to rename a team project through the new Rename team project permission. We have introduced a new "Work" hub in the Admin settings page that combines general settings Figure , Iterations, and Areas in a single tab. With this change, users will see clear differences between project-level settings and team settings. For team settings, users will only see areas and iterations that are relevant to their team. At a project level, the settings page will enable admins to manage areas and iterations for the entire project.

Additionally, for project area paths, a new column called "Teams" has been added to make it convenient for admins to tell quickly and easily which teams have selected a specific area path. This public API allows users to get the process configuration of a given project. The process configuration contains the following settings:. Team Foundation Server introduces a new experience to manage groups and group membership.

For example, 'John D' as well as samaccountname e. In previous releases, you would pick one of multiple configuration wizards for your TFS deployment depending on what you were trying to do.

The Basic and Full wizards could be used to configure a new deployment; the Upgrade wizard could be used for production and pre-production upgrades; and the Application-Tier Only wizard could be used for a variety of scenarios, including scaling out an existing deployment, replacing an application tier with new hardware, and so forth.

In TFS , all of these scenarios have been unified into a single Server Configuration Wizard, which guides you toward and then through each of these scenarios by asking you to make simple choices. Additionally, advanced configurations like pre-production upgrades and clone existing deployment now automate actions that used to be done through tfsconfig.

Once identified, these users will gain full access to all first party TFS extensions installed from the Visual Studio Marketplace at no additional charge. This is helpful if you develop on Linux or Mac and would like to use in any automation tools and GIT. You can manage your personal access tokens from the user security settings page. We are excited to let you know that most of the previous Power Tools have been integrated into TFS Unfortunately, the Process Template Editor has not been integrated, but you can get it in the Visual Studio Marketplace.

The schema for fields on the work item form has changed. The documentation for custom control extensions also changed. See the new documentation: Add a custom control to the work item form. Customers that have a work item page extension installed, who export a work item type definition then import that definition, will get the following error: "The 'LayoutMode' attribute is not declared".

There is an extra LayoutMode attribute on the PageContribution element each time you export a work item type definition. Before importing the definition, search for the PageContribution mode and remove the LayoutMode attribute. In order to give customers time to migrate, we implemented a short-term workaround for RTW. When using NuGet 3. This happens because versions of NuGet before 3.

Versions of NuGet before 3. This may result in unexpected access or lack of access to feeds. If you downloaded an extension from the Visual Studio Marketplace, published it to your TFS installation, and then upgraded to TFS , the extension is not automatically updated when new versions of the extension are published to the Marketplace.

Then reinstall the latest extensions. In TFS we added a feature to automatically check for updated external extensions once a day and upgrade them. When running the Jenkins Queue Job task in a release definition, customers get a server error.

This ability will be added in a future release. Fix up source code as described in this blog post. In the Alerts Administration page, when Team Administrators use the Find Alerts for a specific user search to find subscriptions for a team, they might get an exception. This will show all alerts for all groups that the user has access to.

Option 2: In case the group is a team, instead of searching by team name, navigate to this team's Alerts Administration page to manage subscriptions. These tasks cannot be used for running tests built using Visual Studio RC. For more details, please refer to this blog post. There is no workaround. There is no workaround at this time. We have fixed the issue and the auto update behavior will reach you through TFS Update 2.

If for any reason you cannot wait for Update 2 then reach us through the Support channel and we shall share the fix earlier. If you encounter issues that are preventing you from deploying in a production environment Go-Live , please contact Microsoft product support. English only U. We would love to hear from you! You can suggest a feature, report a problem, and track it through Developer Community and get advice on Stack Overflow.

The Version element scopes a visualization entry to a specific module and version. The Version element helps avoid name collisions, reduces inadvertent mismatches, and allows different visualizations for different type versions.

If a common header file that is used by different modules defines a type, the versioned visualization appears only when the type is in the specified module version. In the following example, the visualization is applicable only for the DirectUI::Border type found in the Windows.

You don't need both Min and Max. They are optional attributes. No wildcard characters are supported. The Name attribute is in the format filename. No path names are allowed. The DisplayString element specifies a string to show as the value of a variable. It accepts arbitrary strings mixed with expressions.

Everything inside curly braces is interpreted as an expression. For instance, the following DisplayString entry:. In the DisplayString expression, x and y , which are members of CPoint , are inside curly braces, so their values are evaluated. The DisplayString element is the only element that accepts arbitrary strings and curly brace syntax. All other visualization elements accept only expressions that the debugger can evaluate.

The StringView element defines a value that the debugger can send to the built-in text visualizer. Adding a StringView element tells the debugger it can display the value as a text visualization. The optional Expand node customizes the children of a visualized type when you expand the type in a variable window.

The Expand node accepts a list of child nodes that define the child elements. If an Expand node isn't specified in a visualization entry, the children use the default expansion rules. If an Expand node is specified with no child nodes under it, the type isn't expandable in the debugger windows. The Item element is the most basic and common element in an Expand node. Item defines a single child element. For example, a CRect class with fields top , left , right , and bottom has the following visualization entry:.

The debugger evaluates the expressions specified in the Width and Height elements, and shows the values in the Value column of the variable window. The debugger automatically creates the [Raw View] node for every custom expansion.

The preceding screenshot displays the [Raw View] node expanded, to show how the default raw view of the object differs from its Natvis visualization. The default expansion creates a subtree for the base class, and lists all the data members of the base class as children.

If the expression of the item element points to a complex type, the Item node itself is expandable. Use the ArrayItems node to have the Visual Studio debugger interpret the type as an array and display its individual elements.

The visualization for std::vector is a good example:. The default value of the array lower bound is 0. To override the value, use a LowerBound element.

You can use the [] operator, for example vector[i] , with any single-dimensional array visualization that uses ArrayItems , even if the type itself for example CATLArray does not allow this operator. You can also specify multi-dimensional arrays. In that case, the debugger needs slightly more information to properly display child elements:. Here's how a two-dimensional Concurrency::array object looks in the debugger window:.

You can use ArrayItems expansion only if the array elements are laid out contiguously in memory. The debugger gets to the next element by simply incrementing its pointer. If you need to manipulate the index to the value node, use IndexListItems nodes. Here's a visualization with an IndexListItems node:. You can use the [] operator, for example vector[i] , with any single-dimensional array visualization that uses IndexListItems , even if the type itself for example CATLArray does not allow this operator.

If the visualized type represents a linked list, the debugger can display its children by using a LinkedListItems node.
