How to compile .NET SDK from source? When I run build.sh, I get a message that the package is being downloaded (I don't understand why, since the goal is to compile). I get a 404 error while downloading and then this:
dotnet_install: Error: Could not find/download: `.NET Core Runtime` with version = 1.0.5
dotnet_install: Error: Refer to: https://aka.ms/dotnet-os-lifecycle for information on .NET Core support

That's normal. You are trying to compile the SDK, which is itself written in C#. You need a C# compiler (such as the one included in the .NET SDK) to compile the SDK itself.
That's not too different from a C/C++ compiler (such as gcc) requiring a C/C++ compiler to build.
I guess the biggest difference is that the required compiler is downloaded automatically instead of failing and asking the user to install the compiler manually.

That's definitely a bug in the SDK build system. I see that you have reported it here: https://github.com/dotnet/sdk/issues/14966. This needs to be fixed by the SDK developers.
