TFS build: Visual Studio 2013 XAML designer ERROR System.MissingMethodException: Method not found: 'Void Microsoft.TeamFoundation.Deployment.Workflow.Activities.MSDeploy.set_DoNotDelete(System.Activities.InArgument`1)'

Description:

When you'll try to edit build workflows (TfvcTemplate.12.xaml or TfvcContinuousDeploymentTemplate.12.xaml) of TFS 2013 using visual studio 2013 with update 4, you will get an error indication (marked in blue) on workflow activities.

At the error list view you'll see the error:

System.MissingMethodException: Method not found: 'Void Microsoft.TeamFoundation.Deployment.Workflow.Activities.MSDeploy.set_DoNotDelete(System.Activities.InArgument`1<Boolean>)'.

Resolution:

The steps below will describe how to use the two DLLs that are missing to the XAML designer.

·         Copy DLL "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\ReferenceAssemblies\v2.0\Microsoft.TeamFoundation.Deployment.Workflow.dll" to "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE" (the correct DLL version 12.0.30324.0)

·         Restart Visual studio

·         Reload the problematic XAML

·         You might get the error: System.IO.FileNotFoundException: Could not load file or assembly 'LibGit2Sharp, Version=0.14.30212.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

File name: 'LibGit2Sharp, Version=0.14.30212.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'

·         To solve it:

-          Create a blank project in visual studio

-          add following dll to references

C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\LibGit2Sharp.dll

·         Add your build XAML to the project
