This is an entirely different toolchain from the official .NET one, which is kind of the point of the post. It is experimental, but intended to for production, not for beating benchmarks.

Rust also builds a pretty small binary, which is cool. This isn't really meant to be a 'C# is better than Rust' post, but more pointing out that Blazor (which is the official MS implementation) builds huge binaries; often >10MB, which is a real problem. This fixes that.
