Cannot run tests in VS2019

[03l54rd1n3]

Hi,

we struggle to get MSpec tests running with the VS 2019 Test Explorer. We have the MSpec Nuget packages in a dedicated Test project and also the VisualStudio.Runner package. The runner extension doesn't seem to be installable for 2019, btw.

When executing tests, we get the following error:

---------- Starting test run ----------
Multiple versions of same extension found. Selecting the highest version.

Can you give me more information? For instance, are you using new-style csproj syntax, which framework are you targeting, etc. Also which version of the Machine.Specifications library are you referencing?

A zipped sample project would help if you can re-create the issue.

Hi, we are targeting .NET framework 4.7.2 with the old csproj format. And these are the versions of Machine.Specifications we have:

[robertcoltheart]

So my first suggestion would be to update your packages, specifically the Machine.Specifications package. It's an extremely old version and the execution code has changed from 0.10.0 onwards I believe.

I'm going to close this as I assume the package updates will do the trick.

Hi, yeah go ahead and close this. Thank you. We'll have a meeting in our company to discuss whether we are going to update this, as it is quite extensive.
