VS2022 Intellisense does not work with TinyCLR extension


I have installed the latest VS2022 and the latest TinyCLR extension. If I create a TinyCLR application, instellisense will not work. It does not show any information for neither .NET nor TinyCLR types. If I create a Windows Forms Application intellisense works as expected.

I have tried to repair and update VS2022 and the extension, but the result is the same.

Have you seen this before?


Did you enable the .NET extension when installing VS?

Skip TinyCLR for a second and try to build a standard .NET windows app to make sure VS/.NET are installed properly.

Yes, I can create a normal .NET application. This is what it looks like when I hover the mouse over “Sleep” in the .NET application:


This is what it looks like if I do the same in the TinyCLR application:


There is no information about the method. It is like if there was no xml documentation file with the dll.

Exit VS and try deleting your bin, obj, and (most importantly) .vs/ directory. The reason is that VS caches a copy of mscorlib in .vs/ and if the signature doesn’t match the TinyCLR one that you are building against (and it won’t) then you won’t get Intellisense. Not a sure fix, but one thing to double check.

Thanks for your suggestion, but the behaviour is still the same.

I can see the documentation from my own classes, but not from the GHI classes.

I have checked the NuGet “packages” folder in my solution, and there are no xml files with the GHI dll’s. This explains why I get no documentation in Intellisense.

I tried to download another TinyClr NuGet package from Bytewizer. The xml files were included with that package, so Intellisense worked as expected.

Do you know why I don’t get the xml files when I install the NuGet packages? I guess you create xml documentation for your TinyClr dlls?
