They're self contained and native, but they're still massive.

There's been some work on CoreRT and a general thrust to remove all dependencies on any reflection (so that all metadata can be stripped) and to get tree-shaking working (e.g. in Blazor WASM).

It seems like in general they're going in this direction.

Smaller is better, of course, but I've never found the size of .NET binaries to be an issue.

What problems does this cause?

If you're trying to pack hundreds of microservices into a cluster, having containers using 80MB of ram minimum instead of 500KB can become a big deal.
