Lab Management 2010: Workflow capability fails with error 'Microsoft.TeamFoundation.VersionControl.Client.ResourceAccessException' was not found.

Symptoms

The work flow capability for lab managed environments can fail with the following error in the Windows Event Viewer on machines(participating in the Lab Managed Environment) where build agents are running:

Exception Message: The constructor to deserialize an object of type 'Microsoft.TeamFoundation.VersionControl.Client.ResourceAccessException' was not found. (type SerializationException)

Cause

This issue can happen if the following two conditions are true:

#1 The "Version Control path to custom assemblies" is defined with a valid source control path hosting custom assemblies. Custom assemblies are used by build definitions for custom tasks. The "Version Control path to custom assemblies" is one of the property options available on the properties page for a build controller. You can use the Team Foundation Server 2010 administration console->Build Configuration and then click on Properties option for the build controller to see the current value of the "Version Control path to custom assemblies" property.

#2 Source Control permissions are by default explicitly denied for the Lab Service Account. This is the reason why the build agent will not be able to access the custom assemblies and the workflow capability fails with the given error.

Resolution

You can grant permissions to lab service account using the ‘tf permissions’ command.

For example: To grant read permissions to lab service account ‘mydomain\labAccount’ on path ‘$/MyProject/CustomAssemblies’, you should execute the following command from a machine that has Team Explorer 2010 installed on it:

C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE>tf permission /user:mydomain\labAccount /collection:http://<tfsserver>:8080/tfs/<CollectionName> /allow:read $/MyProject/CustomAssemblies

Alternatively you may grant read permissions to the lab service account using the Source Control Explorer Security interface.
