VS 2022 wrongly reports error CS0246

Question

Visual Studio 2022 (version 17.12.4) is reporting error CS0246 'type or namespace could not be found...' for a class EposNowReportsDataSnapshot in a declaration:

EposNowReportsDataSnapshot dataSnap = new EposNowReportsDataSnapshot();

The error report is incorrect - the class is declared in a referenced shared project, and the project successfully compiles and runs.

Restarting VS and cleaning and rebuilding the project makes no difference. Is there any way of clearing this report?

Hello @Frank Hindle ,

Welcome to Microsoft Q&A forum.

Is there any warning icon displayed in the referenced assemblies or NuGet packages, like:

If so, perhaps, try to re-add/re-install the assemblies and NuGet packages, then check again. Also, could you confirm that the class/namespace/type is indeed from the added assemblies/NuGet packages(in case there are multiple same-name assembly files, but with the different content/version/path…)?

Update1:

I notice that you have cleaned the project, please kindly double check that following folders: "bin", "obj", .vs(hidden folder), have been cleared manually and then rebuild your project(some files might not be cleared if you just click Build => Clean Solution to clean the solution).

I think you can also try to re-reference the shared project.

There must be some small points that we missed. Could you share(Note: avoid the privacy information) us some corresponding screenshots to check further? Such as project structures, VS Error List/Output Window, the reference manager, the corresponding definition and the code like:

Please feel free to let us know the results.

Best Regards,
