Unit Test error - Could not load file or assembly Microsoft.IntelliTrace.Core

See original GitHub issue

Hi,

When I run unit tests, I get this error. Have you seen it and do you know any solution? I am using Visual Studio 2019 (Version 16.4.5) and FunctionMonkey.Testing package version is 4.0.45-beta.4. (4.0.48-beta.4 has the same error.) Meanwhile, when I just build and run functions, all is OK.

Detailed Error Message

FunctionApp2.Tests.UnitTest1.Test1

It should be ok to use for production now. I am. I’m probably going to move it out of beta in the next couple of weeks but leave the F# and ASP.Net Core support flagging up the experimental warnings while I complete those.

Would love to hear feedback on the commanding too.
