Whenever I edit a build definition for a solution and go to the "Process" tab I get the following error:

Team Foundation Error

Type 'Microsoft.VisuaStudio.Services.Integration.VssAadVSAccountProviderCredential' in assembly 'Microsoft.VisualStudio.Services.Integration, Version=15.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.

I am using Visual Studio 2017 Version 15.2 (26430.16) Release.

Any thoughts?

*Note: it works on VS2012

This seems to be related to the credentials in VSTS, try to do the following:

Reset your credentials

  • Go to Control Panel > User Accounts > Manage Windows Credentials > In tab Generic Credentials, find the one for your TFS server and edit the credentials.

  • If that doesn’t work, try removing the credential.

This is based on this answer
