Compile C# on a (not for) Windows 8 ARM Tablet
arm, c#, compiler-construction, ide, windows-runtime
Solution
Currently: no, and no.
It would certainly be possible to build a Windows Store app that contains an IDE and a C# compiler. However, you would not be able to run any programs built using such an app. Windows Store apps run with reduced privileges in a sandbox. In this sandbox, the CLR will only load system assemblies and assemblies contained in the app package. The app package is immutable and cannot be modified at runtime.
Problem
Would it be possible to code and compile C#, on a Windows 8 Tablet (WinRT) (the ARM processor edition)? Basically it comes down to this: - Is there a C# compiler that runs on ARM? - Is there and IDE that can run in WinRT? If the above is true, I don't see any issue, but I currently can't find if the C# compiler runs on ARM (only a lot of posts about compiling for ARM). I've also looked at SharpDevelop, and found that their source code compiles for "Any CPU", which according to this post: Windows RT and c#, means that it'll run on ARM. Sharpdevelop however requires .NET 4.0 "Full" runtime, which I couldn't find if WinRT has or not. I'm betting it doesn't, as WinRT is supposed to be a really lightweight edition of Windows. As a sidenote, I know that Windows tablets will come in two editions, one for ARM and one for classic processors. The classic processors will run a normal Windows 8 edition, which means it can run all the native applications. Compiling C# wouldn't be an issue here - so the question is rather, can I do the same on ARM? This would be awesome for travelling and trying out new ideas quickly.
