[Proposal]: Native C# compiler support

Native compiler support

• Proposed
• Prototype: Not Started
• Implementation: Not Started
• Specification: Not Started

Summary

Make a C# compiler like C/C++ without Managed runtime support

Motivation

I do like C# language, but it has a huge managed runtime, I do hope C# language has native compiler support.

Now I'm using C# native version: Vala

Does NativeAOT meet your requirement? There are even someone using it to write UEFI firmware (of course not using the BCL).

[taozuhong]

Yet meet the requirement, the NativeAOT has many limitations.

[huoyaoyuan]

What are the specific limitations? A lot of limitations are bound tightly to the type system model used by C#.

[HaloFour]

I don't believe the language specification takes an opinion on subjects like this. That'd be up to the implementation of the compiler.

[taozuhong]

Kotlin has a native compiler, Go/Rust/Swift are native compilers too, maybe C# too.

What's not sufficient about Single file deployment & Native Compilation.

[HaloFour]

This is not the repository to discuss a native compiler. The language specification of C# doesn't care about whether it is natively compiled or not.

Microsoft already has projects to support native execution on various platforms, such as NativeAOT and Xamarin.
