API to retrieve the entry assembly

[bruno-garcia]

The standard API to get it is:

Assembly.GetEntryAssembly()

The problem is it can return null.

We need a reliable way to get the top most entry assembly. In case it was unmanaged, then the first managed after that should work fine.

One of the approaches is to stack walk until locating the call from unmanaged code and take the assembly immediately before that. That was implemented on SharpRaven which could serve as a good starting point. It's based on an SO answer but added support to Mono too.

The goal here is to have a simple API that will make an extra effort to find the main application assembly.

Proposed API:

public class AssemblyInfo
{
    public static Assembly GetEntryAssembly();
}
