How can I get Microsoft.AspNetCore.Authentication.OAuth 9.0 as a standalone assembly?

[epsitec]

I am using the OAuthTokenResponse class from Authentication.OAuth.

When referencing the AspNetCore framework through a <FrameworkReference> in my project, this works fine:

  <ItemGroup>
    <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>

However, the class library cannot be used from a Blazor WASM project.

Now, if I try to reference Microsoft.AspNetCore.Authentication.OAuth directly:

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Authentication.OAuth" />
  </ItemGroup>

then the most recent version I find on NuGet is 2.3.0, which is still using Newtonsoft, and is not compatible with my own code, which is using System.Text.Json.

How (or where) can I get the 9.0.0 version of the assembly? Or is this by design?

You can't - the NuGet package is not shipped separately, which is why you can't find any versions newer than 2.x in NuGet.org.
