I got a new computer and what was working in NCrunch on my old computer, now have "Analyse Assembly" failures for our tests assemblies.
I'm not sure what to look for. The projects build fine in VS (and Resharper). I've disabled Windows Defender to no avail.

NCrunch version 4.4.0.12
VS2019 16.7.6
Projects are in .Net Core 2.2
We use x64 satellite hosting strategy (and tried x86) and Optimised Instrumentation mode.

Here is the log for one of our failing project in NCrunch.

Thanks a lot
Phil

Hi Phil,

Thanks for sharing this problem.

The error described here is one kicked up by the engine when the test process disappears without warning and with no information available. Usually this is an install state issue (i.e. something is wrong in the configuration of the machine or something isn't installed when it should be). The lack of useful error information always makes this sort of thing very frustrating.

Can you check whether you have the runtime for the requested version of .NET Core installed? Make sure you have both the 32bit and 64bit variants if you are targeting specific processor architectures (they are installed separately). Sometimes you can find error information in the Windows Event Viewer.

Oh that was it. I had .Net core 3.1 installed but not .net core 2.2 🤦‍♂️.
No idea why it works fine in VS but not in NCrunch.

Thanks a lot for the tip
