There is also the dotnet-install scripts https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-i...

In my experience installing the .NET SDK is fairly simple in any platform, well documented and supported.

Nuget.config allows to configure your local feeds, this implies you have a local feed with the required packages.

Another option is to push the local build packages to you local NuGet cache.

Just install the .NET SDK, and you’re ready to go.

Nuget is complete and utter garbage. You still have to resort to all forms of unreliable hacks in order to redirect it to a locally clone

How so, you can use a nuget.config in your project and use your local packages fairly easy, seems in part with npm and the likes.

Can I map multiple custom types to the same C# type? :)

Yes that is totally fine. In C# side both would be represented as "long[]", the generated code would use the appropriated encoding for the custom type, as provided by the user methods.
