Suddenly, when queuing builds in TFS based on a git team project, I get the following stack trace.

Exception Message: Attempted to access an unloaded AppDomain. (type AppDomainUnloadedException) Exception Stack Trace: Server stack trace: at LibGit2Sharp.Core.NativeMethods.git_clone(RepositorySafeHandle& repo, String origin_url, FilePath workdir_path, GitCloneOptions& opts) at LibGit2Sharp.Core.Proxy.git_clone(String url, String workdir, GitCloneOptions& opts) at LibGit2Sharp.Repository.Clone(String sourceUrl, String workdirPath, CloneOptions options) at Microsoft.TeamFoundation.Build.Activities.Git.GitPull.GitClone.GetRepository(String repositoryUrl, String workingFolder, Boolean checkoutSubmodules) at System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Object[]& outArgs) at System.Runtime.Remoting.Messaging.StackBuilderSink.AsyncProcessMessage(IMessage msg, IMessageSink replySink)

Exception rethrown at [0]: at System.Runtime.Remoting.Proxies.RealProxy.EndInvokeHelper(Message reqMsg, Boolean bProxyCase) at System.Func4.EndInvoke(IAsyncResult result) at Microsoft.TeamFoundation.Build.Activities.Git.GitPull.GitRepositoryBase.EndExecute(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity1.System.Activities.IAsyncCodeActivity.FinishExecution(AsyncCodeActivityContext context, IAsyncResult result) at System.Activities.AsyncCodeActivity.CompleteAsyncCodeActivityData.CompleteAsyncCodeActivityWorkItem.Execute(ActivityExecutor executor, BookmarkManager bookmarkManager)

I changed nothing for this to happend, googling so far I found info about it perhaps being macafee, but we dont use that on our build agent.

  • Using an on-premises build server
  • Normal TFS team projects build as expected

Which version of TFS? Which of the updates has been installed on it? – jessehouwing
Version 14.0.22824.0 – submarines
No updates have been made in between the builds – submarines
Please upgrade to Release Candidate 2 of TFS 2015 before continuing. Make sure you have a backup of your current database and keep it, as there are known issues that can cause dataloss on older preview and release candidates. Your TFS should be at least 14.0.23102.0 tfs2015. – jessehouwing

Resolved by restarting the server - not sure how I didn't think of that.
