CodeLens feature in Visual Studio 2013

CodeLens is a new feature in Visual Studio 2013 ultimate, it displays useful information about the code directly inside code editor. The information it displays includes method references, tests associated with a method, code history, associated bug etc. To get the same information without code lens, users have to dig through several windows which takes away from writing code.

By default, Code Lens feature is enabled in Visual Studio 2013 Ultimate. To modify the settings of CodeLens, users have to go to Tools –> Options –> Text Editor —> All Languages –> CodeLens. Here, users can either turn on – off complete Codelens functionality or specific pieces from the available list.

Some of the CodeLens features don’t work with previous versions of Team Foundation Server. Here’s the CodeLens feature matrix for different versions of Team Foundation Server.

Currently, CodeLens is supported only when editing C# and VB.NET.

CodeLens indicator sample:

For example Tested By indicator shows the tests available for a particular method. In below figure, it shows that there are two tests available for the method, and none of them have been executed.

Clicking the link displays the tests, and it also allows users to run a specific test or all tests related to the method. Users can click the Run All link to run all the associated tests. Below fig shows the results, with one test passing, and the other test failing.

CodeLens provides useful information without getting in the way or becoming distracting. The ability for a developer to stay in the code editor while receiving detailed information from multiple parts of the codebase and Team Foundation Server is definitely a useful feature.

Code Review feature in Team Foundation Server

Team Foundation Server 2012 and later versions provides in-built code review workflow feature. Code Review can be initiated either when user has some pending changes in workspace (before a Check-in) or after a check-in from change sets option.

Request a Code Review before check-in: A Code Review workflow can be initiated for In-Progress work by clicking Request Review option under My Work tab.

clip_image001

Request a Code Review after check-in: Code Review can be initiated after a check-in by clicking Request Review option for particular changeset from history tab.

clip_image003

In both the above scenario’s, request review option will take the users to the New Code Review pane in My Work tab.

clip_image004

Here, the requester can add below items before submitting the review request.

  • One or multiple code reviewers
  • Title, Area Path and Description for the In-progress work

If user clicks Submit Request option, pending changes will be automatically shelved and the Code Review Request work item will be created. It’s assigned to the users mentioned in Add Reviewers field.

The reviewers will be notified if they have the email alerts configured for code reviews. If not, they can find the review requests assigned to them in Code Review and Requests section under My Work tab.

clip_image005

Reviewer can double click an item from the list to review the changes.

clip_image006

Reviewer can go through the changes in files attached to the particular review request and complete the review.

Once review is done, the reviewer can simply click Send & Finish to close the review and post feedback to the requestor.

After reviewer submits the feedback by clicking Send & Finish option, the status with comments will be available under requesters My Work tab.

My Work feature in TFS

A typical development workflow will follow below steps when connected to the TFS version control system.

  1. Open a project
  2. Make some changes
  3. Enter a comment describing the changes made
  4. Associate the work items related to the changes
  5. Check-in changes

This workflow holds well if user is working on a single task a time. But, it gets increasingly difficult to keep track of changes when working on multiple tasks at the same time. The new “My Work” feature addresses this problem, it gives users a place to review the work that’s currently assigned and keeps track of different tasks.

My work page will show all the To Do and In Progress tasks assigned to the user based on a work item query. If the user want to start the work on a To Do task then user can either drag n drop the task from To Do to In Progress tab or can right click the task and click the Add to In Progress option.

clip_image001

If user haven’t made any changes to the project, will see only “Finish” and “Suspend” options and no “Check In” option.

clip_image002

Once user make some changes to the project, will see different options.

  • Check In
  • Request Review
  • Suspend

clip_image003

The first option will check-in the changes to version control system and the second option Request Review will start the Code Review workflow. The last option Suspend will move all the changes to a shelveset and the changes are undone from user workspace.

clip_image004

At this point, user will have a very clean looking workspace and he can start the work on another task either by moving a To Do task to In Progress tab or clicking Resume option on existing suspended work.

The Suspend option captures all IDE state including files, tool windows, bookmarks, breakpoints, etc so that user can return exactly to the same state later. This feature significantly decreases the delays caused due to switch contexts and interruptions.

TF215097: An error occurred while initializing a build for build definition \project name\build definition name

Issue: TF215097 An error occurred while initializing a build for build definition \projectname\build definition name: Cannot create unknown type ‘{clr-namespace:BuildActivitiesLib.Activities;assembly=BuildActivities}Checkout’.

Solution: We have developed lot of custom build activities and usually upgrade them with our Team Foundation Server upgrades every major release. We recently upgraded to TFS 2013 and as part of build upgrade we have rebuild all the activities with latest version of Visual Studio, TFS Assemblies and .Net framework version. All the build controllers were pointing to TFS 2013 compatible custom activity binaries.

We started getting above error on a particular build server which is still running on Team Foundation Server 2012 build services. This server is not upgraded to latest version of TFS build due to the operating system limitation and we didn’t go for OS upgrade because TFS 2013 supports TFS 2012 build services.

But, looks like the custom build activity assemblies should match with Team Foundation Build Services version and not with the Team Foundation Server. We are able to resolve the issue with TFS 2012 build controller by changing custom assemblies path to point to TFS 2012 compatible libraries path.

TF400018: The local version table for the local workspace could not be opened.

Issue: TF400018 The local version table for the local workspace workspacename;username could not be opened. The workspace version table contains an unknown schema version.

Solution: This error usually occurs due to workspace getting corrupted especially when Local workspaces are configured. This error doesn’t allow you to view the source control explorer. To resolve this and to re-use the same workspace, you have to rename the $tf hidden folder which will be created at the root of your local workspace mapped folder.

Copy files in TFS Build

Team Foundation Build workflow provides Copy Directory activity to copy the folder content but its doesn’t have an activity to copy the files. If you need to copy  files as part of the build process then you have below options.

  • Write a custom activity for copying files
  • use Invoke Process activity to call the xcopy or robocopy commandline tools

In this post, I will show the steps to copy a file using Invoke Process activity and xcopy command.

First, you need to drag and drop the InvokeProcess activity from toolbox to the workflow template.

image

This activity contains below properties.

image

FileName (String): FileName of the process that you want to start.
Arguments (String): Command-line arguments that you want to pass to the process.
EnvironmentVariables (IDictionary<TKey, TValue><String,String>): Additional environment variables and their values.
OutputEncoding (Encoding): Encoding that is used to read the output and error streams. Default value will work for scenerios.
WorkingDirectory (String): You can specify the working directory (WorkingDirectory) in which you want to run the process.                                                                                                                                                                                                                                 

Result(Int32): Returns the ExitCode from the process.

For the copy file activity, here are the sample values for above properties.

image

Additionally, Inside the InvokeProcess activity you need to add two activities to display the standard output and error output from your process
WriteBuildMessage activity: This activity should be added under Standard Output, and its property should be set to stdOutput.
WriteBuildError activity: This should be added under Handle Standard Output, and its property should be set to errOutput.
