I have a solution with a .NET Core project and lots of .NET Framework projects. It's been working fine until "some point in the past couple of weeks" - no major additions, sorry I can't be more specific.

I'm on latest VS 2017 (15.4.1)

NCrunch tests status bar: "1 project is failing to build"
VS NCrunch status bar: brown circle around "1" - "1 project is failing to build, NCrunch engine is idle".

.NET Core project (RedactedAuth): ok, green tick (no tests - correct)
Unit test project: green question mark, lots of tests shown, "Build successful".
.NET class library project: "Last build successful, rebuilding", clock icon. Note: no build is in progress.

Selecting any of these 3 projects yields no details (e.g. exceptions) in the lower pane.

The "Tests" output pane shows:

[24/10/2017 12:03:09 Error] The operation failed as details for project RedactedAuth could not be loaded.

...but I'm not sure that's NCrunch related.

Let me know if I can provide any further info.

Hi, thanks for sharing this problem.

Probably the build for the .NET class library has hung or terminated unexpectedly. Is there any information showing for this project in the Processing Queue Window?

Hi thanks for the response. No unfortunately the output window (umm, the bottom pane) is blank for all of the projects in question when selected
