"Duplicate frameworks found" when restoring using static graph

[martinrrm]

I can repro it in my local machine

@snorrk Hi! I investigated a little bit and looks that the problem is that your project extension .proj doesn't import the necessary targets, basically is not supported to have a .proj extension and Microsoft.NET.Sdk project. Can you try do rename the project file to .csproj and see if it works? Thanks!

Not being able to restore using static graph with Microsoft.NET.Sdk is the point of this issue.

Sdk.targets says:

This means support for different languages could either be supplied via an SDK or via a NuGet package

This does not work when static graph is enabled (but does when it is disabled).

I believe that is a bug, the behavior should be consistent regardless of the static graph setting?

@snorrk what happens when you build the project?

D:\repros\duplicate-net40>msbuild /clp:v=n;summary;forcenoalign
MSBuild version 17.9.5+33de0b227 for .NET Framework
Build started 3/12/2024 3:18:20 PM.

Project "D:\repros\duplicate-net40\Project.proj" on node 1 (default targets).
C:\Program Files\Visual Studio 2022\MSBuild\Current\Bin\amd64\Microsoft.Common.CurrentVersion.targets(1248,5): error MSB3644: The reference assemblies for .NETFramework,Version=v4.0 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks [D:\repros\duplicate-net40\Project.proj]

Build FAILED.

Since the project file's extension is .proj, the Microsoft.NET.Sdk does not import the C# targets that enable multi-targeting. Since the value of <TargetFrameworks /> isn't interpreted by the SDK when the project file extension isn't .proj, it defaults to .NET Framework v4.0.

If you're building a C# library or application, the project file must end in .csproj. If your project is not compiling an C# program or library, consider Microsoft.Build.NoTargets.
