[BUG]: C# command line options are ignored about compiler-explorer HOT 6 OPEN

At the start of adding dotnet languages to CE, it was a choice to limit the parameters to increase compatibility with the compiler and crossgen2, so I don't think we can just add support for all parameters, but langversion should probably work.

I don't understand. What kind of compatibility issues are there if compiler flags are allowed?

from compiler-explorer.

Those compiler options are passed to crossgen2/corerun, not roslyn/msbuild.
We should really have a place to document the available options on the website.

Also note if you want to use top-level statements, be sure to check the output option "Link to binary".

Why aren't they passed to roslyn? That's what I would expect.

The main purpose of using compiler-explorer is to aid the codegen disasm, while changing options passed to roslyn doesn't affect codegen at all.
