Description

After upgrading to TFS2012, we get the above Code Analysis error when executing builds. This happens from time-to-time, not always.
This was a known problem in TFS2008 because of a multi-threading issue in Static Code Analysis. It was, however, fixed in TFS2010, but now it seems to have been reinvented again in TFS 2012.

CA0001 : Rule=Microsoft.Performance#CA1811, Target={XXX}.#SerializeObjects(System.Collections.Generic.List`1<System.Object>) : Collection was modified; enumeration operation may not execute.

This issue should be re-opened because this has been a continuous issue for our team . We run TFS 2013 + Update 4 and the build agent is on a Windows 7 and VS 2013 + Update 4 workstation.

We never see this issue when running CA via VS as it seems to be a TFS only issue. We get roughly 5 failed builds per week due to this problem and would estimate something like 50 builds per week.

Is there any kind of verbose/diagnostics log we can send to help sort this out?

As we're still unable to reproduce this Code Analysis issue ourselves, I'm going to resolve this as Not Repro for now. If you can submit a zipped project that demonstrates this issue occurring, please do reactivate the bug so we can take a look.

Thanks again!

Thanks for reporting this issue you've encountered with Visual Studio!

We've attempted to reproduce this build race condition ourselves, but have so far been unable to see it happen. We'll need you to attach a small demo project that shows this issue occurring. Once we have such a project, we can continue investigating this bug.

Thanks again!
