cannot open source file

After deleting my bin/obj folders, I get this when trying to build:

c1 : fatal error C1083: Cannot open source file: '<path>\BC3\obj\Debug\net6.0-windows\win-x86\dnne\BC3.g.c': No such file or directory

I’ve seen this with multiple projects (I’ve created new projects multiple times when encountering this problem).

This is an x86 project and does have

<RuntimeIdentifier>win-x86</RuntimeIdentifier>

set per #58 and this commit .

Another thing that concerns me about this message is that it means VS is trying to run cl.exe in its design-time build, which is totally inappropriate

@AArnott That is entirely possible and likely the case. I wrote most of this while testing outside of VS. I assume following these docs will help avoid a majority of these problems, https://github.com/dotnet/project-system/blob/main/docs/design-time-builds.md.

Another thing that concerns me about this message is that it means VS is trying to run cl.exe in its design-time build, which is totally inappropriate, as it will slow down a great many other design-time experiences in VS. In fact this failure appears to be breaking the design-time build, which is now producing many more errors in the error list as the language service cannot fully initialize.
