Csproj.Sdk is msbuild SDK collection for C# project (.csproj file) to migrate legacy-style project to newer SDK-style format.

How to Migrate .csproj to SDK-Style

For example, use Csproj.Sdk.Void as an SDK for your .csproj.

<Project Sdk="Csproj.Sdk.Void/1.1.0">
    ...
    ... original file contents except for <Project> tag ...
    ...
</Project>

Note

Version prefix (/1.1.0) must be specified to activate internal nuget resolver.

This will make project sdk-style and allow setting nullability for whole project by adding <Nullable>enable</Nullable> to .csproj. Surprisingly, nullability setting is not recognized by Visual Studio if Project tag doesn't have Sdk attribute!!

See: <Nullable> has no effect in old-style csproj

Available SDKs

Csproj.Sdk.Void

src/Csproj.Sdk.Void/

This SDK will not do anything, is just for converting legacy-style project to sdk-style.

Csproj.Sdk.Unity.VisualStudio

T.B.D.

Unity Integration

To migrate Unity project to sdk-style format, see Unity/README.md

Note: Unity's Visual Studio Editor package changelog describes that adding support generation of SDK-style project, but unfortunately, it still generates legacy-style format with some changes such as project header updated to <Project ToolsVersion="Current">. (actually it is sdk-importing-legacy-style project)

And also sdk-importing-style format generation is only performed when External Script Editor is set to VS Code. Unity is still generating legacy-format for Visual Studio environment.
