Java made the mistake of being VM based, no value types, and AOT only available via expensive 3rd party plugins.

Had Java been like Modula-3 or Eiffel since version 1.0, Go might never have happened at all.

Thankfully they are on the right path to fix those issues.

So Microsoft created C# to address that

No it didn't, it created C# because they got sued by Sun due to the J++ extensions, none of them were related to value types and AOT.

J++ extended Java in having a Windows specific framework JFC, Java Foundation Classes, what later became Windows Forms.

Support for events and J/Direct, which is basically how P/Invoke came to be on C#.

.NET has always supported a basic kind of AOT via NGEN, which only supports dynamic linking, AOT has to be done at install time, requires strong named Assemblies and it is tailored for fast startup leaving the rest of the work to the JIT.

If it wasn't for the lawsuit, C# would never happened, in fact the research being done with COM vNext used J++.

The biggest issue with C# is that the only real implementation was closed source and Windows-only until recently.

Additionally, AOT is still experimental, and doesn't support ASP.Net Core yet.
