I justed tested compiling source code package of v8.9.0.0 with VS 2022 and it works?

Did you load GleamTech.FileVista.sln solution file?

Don't delete TargetFrameworks for sub projects. FileVista project will use net461 target but sub projects target both net461 and netstandard2.0.

 

One possible issue is that you deselected .NET SDK (not the .NET Framework SDK) with your VS 2022 installation. Open Visual Studio Installer and ensure .NET SDK is selected and maybe also .NET 6.0 Runtime. Even if you don't use .NET (formerly .NET Core), for building sub projects you need the SDK.

No joy. Build output:

Just saw your second post. Will try that solution.

Should I install 4.6.1 SDK?

> No. I did update NuGet packages before compiling. 

FileVista source code package is self-contained does not depend on any NuGet packages, you just open GleamTech.FileVista.sln with VS 2022 and compile. Also note that the DLL's produced by the compile can not be mixed/used with our product NuGet packages.

FileVista-v8.9.0.0-Source\ProductReferences\Unsigned\net461 folder contains unsigned version of DLLs used only by FileVista source package. The projects reference these not the NuGet packages.

> Should I install 4.6.1 SDK?

No, .NET Framework 4.8 SDK and targeting pack should be sufficient as it's backwards compatible.

The build output posted above is clean compile after loading the solution and without NuGet update (thanks for that information). I will study a bit more at my end and report back. Thanks Cem.

Ok good to know. By the way, I just noticed we were stripping netstandard2.0 targets from projects (from TargetFrameworks element) for FileVista source code package so you shouldn't even need the .NET SDK.

Your problem was simply maybe not opening GleamTech.FileVista.sln with VS 2022.

I think I have a permissions issue. I moved the code to my VS 2019 projects folder and build resulted in this:

I suspect the warning came up in in the VS 2022 projects folder and I did not see it a "allow". I will fix that and report back.
