Cannot build net7.0 with FSharp.Compiler.Service 42.7.100

Cannot build net7.0 with FSharp.Compiler.Service 42.7.100

Repro steps

With the latest Visual Studio 17.4 and its .NET 7 SDK and templates, in a new folder with the test project name invoke:

dotnet new console -lang f#

It creates the net7.0 console app F# project. Then add the latest FSharp.Compiler.Service 42.7.100:

dotnet add package FSharp.Compiler.Service --version 42.7.100

It fails:

> dotnet add package FSharp.Compiler.Service --version 42.7.100

To work around, add this reference manually to the project file:

  <ItemGroup>
    <PackageReference Include="FSharp.Compiler.Service" Version="42.7.100" />
  </ItemGroup>

and build

dotnet build

It fails due to not found Microsoft.Build.* packages:

New FCS 42.7.101 works, thank you!

FWIW it looks like the required Microsoft.Build.* packages 17.4+ are not available on NuGet.
