vstest: System.MissingMethodException Method not found: 'Void Microsoft.VisualStudio.CodeCoverage.Shim.1017596829__coverage_runtime_method__32412_19337__(UInt64)'.

Description

When using the /Enablecodecoverage option on vstest.console.exe, we occasionally see a MissingMethodException about the injected Shim method for the code coverage. This appears during calls than span across a new AppDomain.

i.e. System.MissingMethodException Method not found: ‘Void Microsoft.VisualStudio.CodeCoverage.Shim.2218451032__coverage_runtime_method__56282_18307__(UInt64)’.

Please this this related post we created about 4 years ago. This post is slightly different because it’s dealing with IIS, but might be related due to dealing with AppDomains. https://social.msdn.microsoft.com/Forums/vstudio/en-US/3f7415ed-7e17-496b-b705-3055c48a4406/iis-codecoverage-occasional-method-not-found-microsoftvisualstudiocodecoverageshim?forum=vsunittest

Steps to reproduce

Develop a unit test that makes a call across an app domain. You’ll occasionally see this exception (not always).

Expected behavior

There should be no exception

Actual behavior

We see the MissingMethodException
