Hi,
After migrating from dotnet core 2.2 to 3.0 our team started to get this error:

Reproduced with dotnet core 3.1 (same issue with 3.0):
https://github.com/PavelA85/nCrunchReporduce

NCrunch latest version
Visual studio 2019

Any way to fix this issue?

Hi, thanks for sharing this issue. I've reproduced it using your sample and concluded that it seems to be triggered by the specification of a win10-x64 RuntimeIdentifier in the targeted project.

I'm not yet sure why this is the case. We're going to need to do more digging. We'll let you know when we have a solution available.

I'm also having the same issue.
any ideas or suggestions or temporary workarounds would be most welcome!

The same here - I have NUnit test project targeting netcoreapp3.0, RuntimeIdentifier= win-x64 and Microsoft.NET.Test.Sdk = 16.4.0.

I'm using NCrunch 4.1.0.1.

Please could you notify me when a fix is available.

Many thanks!

Hi,
thank you for update.
I am still getting error in my production solution.
output:


We found workaround for now:
Code:
<RuntimeIdentifier Condition="'$(Configuration)'=='Release'">win10-x64</RuntimeIdentifier>

We use conditional RuntimeIdentifier, that is applied only in CI pipeline

We've updated NCrunch with some better handling of the new implicit framework references that were introduced in .NET Core 3.0 (this fix didn't get included in the build published above). It's worth trying this build to see if it resolves both of the problems you're experiencing:

NCrunch_Console_4.2.0.4.msi
NCrunch_Console_4.2.0.4.zip
NCrunch_GridNodeServer_4.2.0.4.msi
NCrunch_GridNodeServer_4.2.0.4.zip
NCrunch_LicenseServer_4.2.0.4.zip
NCrunch_VS2008_4.2.0.4.msi
NCrunch_VS2010_4.2.0.4.msi
NCrunch_VS2010_4.2.0.4.zip
NCrunch_VS2012_4.2.0.4.msi
NCrunch_VS2012_4.2.0.4.zip
NCrunch_VS2013_4.2.0.4.msi
NCrunch_VS2013_4.2.0.4.zip
NCrunch_VS2015_4.2.0.4.msi
NCrunch_VS2015_4.2.0.4.msi.7z
NCrunch_VS2015_4.2.0.4.zip
NCrunch_VS2017_4.2.0.4.msi
NCrunch_VS2017_4.2.0.4.msi.7z
NCrunch_VS2017_4.2.0.4.zip
NCrunch_VS2019_4.2.0.4.msi
NCrunch_VS2019_4.2.0.4.msi.7z
NCrunch_VS2019_4.2.0.4.zip

Assuming this doesn't work, is there any chance you could extract a particular file for me from the 3.0 failure and submit it through the NCrunch contact form? Right-click on the failing project, go to Advanced and choose to browse to the workspace. Find the bin\debug folder (or your build output directory), then look for a file called nCrunch.TaskRunner.DotNetCore.20.x64.deps.json. This file contains the dependency data for your test environment and lately it's been the cause of these exceptions under .NET Core 3.0. If I can have a copy of this file there's a good chance I can establish the source of the failure.

Regarding the .NET Core 3.1 issue ... We haven't done much in the way of testing with this framework yet, though it's still our goal to resolve issues encountered with it. The problem in this case looks like it might have a wider scope than NCrunch. Can you confirm that the project builds successfully using Visual Studio and MSBuild? I might need to get a code sample that can reproduce the issue if you're able to construct one. The problem is almost certainly dependency related and probably doesn't require any of your actual source code.

By mistake I intalled NCrunch_Console_4.2.0.3.msi instead of NCrunch_VS2019_4.2.0.3.msi
I have installed NCrunch_VS2019_4.2.0.3.msi and it works as expected, projects with
Quote:
<RuntimeIdentifier>win10-x64</RuntimeIdentifier>

are build as expected.

I will install NCrunch_VS2019_4.2.0.4.msi and get back if any issue is found.
