Everything working fine yesterday.....

Windows update overnight to OS Build: 19043.1110

Running:
VS 2019 16.10.3
NCrunch 4.9.0.8

22 Projects, mostly .Net 4.7

One Blazor project (.Net 5.0) and this is the one that NCrunch is having issues loading (Load Failure). It builds and runs perfectly in Visual Studio.

The same solution still works on my Laptop OK (NCrunch loads projects), but I have not yet updated that.

I'm looking for ideas of where to look for the problem.

Thanks!

I have submitted the bug report as requested.

I'm not sure how to build this project with msbuild. I followed online info @ Microsoft and got this:

error MSB4041: The default XML namespace of the project must be the MSBuild XML namespace. If the project is authored in the MSBuild 2003 format, please add xmlns="http://schemas.microsoft.com/develop
er/msbuild/2003" to the <Project> element. If the project has been authored in the old 1.0 or 1.2 format, please convert it to MSBuild 2003 format.

Given that I always build from within the GUI I may need a little coaching on how to do exactly what you need. Note this is a .Net 5.0 project.

Well, the good news or bad news is it does not build. Why would it build via the GUI but not via the command line tool?

The errors are all similar to these:

C:\Development\{Path}\{MorePath}\{ProjectPath}\_Imports.razor(8,27): error CS0234: The type or namespace name 'Shared' does not exist in the namespace '{Project}' (are you missing an assembly reference?) [C:\Development\{Path}\{MorePath}\{Project}\{ProjectName}csproj]

C:\Development\{Path}\{MorePath}\{ProjNameHere}\obj\Debug\net5.0\Razor\Pages\Unsubscribe\Unsubscribe.razor.g.cs(115,33): error CS0115: 'Unsubscribe.BuildRenderTree(RenderTreeBuilder)': no suitable method found to override [C:\Development\{Path}\{MorePath}\{ProjectPath}\{ProjectName}.csproj]


HOWEVER, on the laptop where NCrunch is still working - I get the SAME errors running the MSBuild from the command line. < scratch head />

Thanks.

I did a repair and it made no difference.

Another developer I work with has the same Windows update, same version of Visual Studio, same version of NCrunch and same project, and it loads without any issues.

Not sure where to go from here.

AWESOME!!



No matter. If a reinstall fixed it, likely knowing the details wouldn't help much anyway. The answer would simply be to advise a reinstall. That said though, I've never seen this issue be caused by a faulty install of NCrunch before.

We've had this happen to us in our dev environments here before too. My suspicion is that the uninstaller can leave files behind if they are in use by background processes. There are a number of areas of the toolset where the chosen version of .NET is determined by which directories exist (regardless of whether they happen to be empty).

Good find :)

I have been getting this error message for a while. I had installed the dotnet6 RC but added local global.json files to the project so they continue to build with dotnet 5 to keep local consistent with the build servers:



I removed dotnet6 as I was only playing with some features - but left the global.json files. Removing the global.sjon files solved the problem

Hopefully this will help someone else - lost hours on this
