Consider expanding JIT Asm support

Currently the JIT Asm results target only targets Desktop CLR and does not let you select 32-bit vs 64-bit (you can select 32-bit vs 64-bit for the main C# compiler only).

Given that most runtime improvements are happening on CoreCLR, it would be beneficial if you could select the target runtime for the JIT Asm target (if nothing else).

Given that the compiler can target any cpu target (AnyCPU, x86, x64, ARM64, etc), it would be also be beneficial if you could select which assembly output you want.

This effectively gives you the following options:

• Language (C# vs VB vs F#)
  • Language Version would also be nice (i.e. LangVersion=7.3 vs Preview vs Latest)
• Compiler Version (Latest Release vs Preview Branches)
• Results (all of this applies to JIT Asm, I think there are sandboxing concerns for things like Run)
• Runtime (Desktop vs CoreCLR vs Maybe Mono)
  • Runtime Version would also be nice
  • Target CPU would be nice (x86 vs x64 vs ARM vs ARM64)
• Configuration (Debug vs Release)

Hi everyone! Thanks for your discussion so far.

Revisiting this ticket after a while, I think it is quite wide and so is a bit hard to track. For example, I can only mark it as done once every mentioned feature is implemented – and looking at glance it’s not immediately clear which ones already are.

Please create individual tickets for specific requests, e.g. Mono support, and it will be more likely those can get prioritized and done, or at least discussed in more detail.

And I’ll close this one for now.

Having Mono runtime could be useful for checking how the codegen would look in game engines that use it, for example Unity. Would be nice if it was added.
