I've been looking into the idea of writing a CLI interpreter myself  
and I noticed that mcs and gmcs emit a Microsoft-style metadata  
version string in the assembly. Did you find a way for your  
assemblies to strictly adhere to the ECMA standard?

ECMA-335 3rd and 4th edition both define "Standard CLI 2005" whereas  
[g]mcs uses .NET's proprietary "v1.1.4322" and "v2.0.50727", in  
theory making assemblies incompatible with purely ECMA-compliant CLI  
implementations.
