How do I choose which compiler to use for my C# scripts?

Under publishing settings on Windows Store player settings, there’s a drop down menu called “Compilation overrides”. There are 3 settings:

1. None. All C# scripts will get compiled with Mono C# compiler;
2. Use Net Core Partially. Scripts that are in folders “Assets/Plugins”, “Assets/Standard Assets” and “Assets/Pro Standard Assets” will get compiled with Mono C# compiler, while the rest will be compiled with Microsoft C# compiler;
3. Use Net Core. All scripts will get compiled with Microsoft C# compiler.

Both compilers have their ups and downs. Compiling scripts with the Mono C# compiler will allow them to be referenced by JavaScript scripts, which, for example, is needed for Angry Bots (hence you have to set it to none). However, using the Microsoft C# compiler will allow you to use Microsoft specific APIs without the need for plugins - just wrap the code in #if NETFX_CORE/#endif, and it will compile and work just fine.

Breakpoints in generated Assembly-CSharp-* projects aren’t hit.

There could be couple of reasons:

• This may occur because of the JIT optimization on module load. In Visual Studio, go to Tools > Options > Debugging > General and uncheck Suppress JIT optimization on module load.
• Visual Studio doesn’t consider Assembly-CSharp-* as your code. Go to Tools > Options > Debugging > General and uncheck Enable Just My Code. This tells Visual Studio that you want to debug the Assembly-CSharp-* projects.
