Some ideas:

• Can dotnet-ef use the MSBuild object model?
  • See https://github.com/NuGet/NuGet.Client/blob/fe240c4f457b30050e963dc19f916773ddf21d38/src/NuGet.Clients/NuGet.CommandLine/MsBuildUtility.cs
  • Makes Tools ignore $(BaseIntermediateOutputPath) #18060 and dotnet ef migrations fail when using custom output paths and separate project/startup-projects #23853 easier
  • Consider shipping EntityFrameworkCore.targets in buildTransitive instead of creating dynamically.
• Can ef.exe use AssemblyLoadContext instead of dotnet exec?
  • Could make it a single-file executable
    • Easier to use directly on assemblies (issue Running migration on published dll #16882)
    • Easier to use without the SDK (on the server/in a container)
  • Building block to enabling Xamarin/UWP projects (Tools: Support Xamarin/MAUI Projects (currently requires separate .NET Standard class library) #7152)
• Use System.CommandLine
