CF20 will not compile in VS2005

What steps will reproduce the problem?
1. Open protobuf-net-cf20.csproj in VS2005 (see issue 227 if it fails)
2. Build Solution

What is the expected output? What do you see instead?
Expected it to compile cleanly but got 2 errors on things
that does not exists in this version of CF

What version of the product are you using? On what operating system?
Windows XP, VS2005, r444 of protobuf-net

Please provide any additional information below.
This is triggered by the fact that __string__ in this version of CF at least 
does not have the .Contains method and that 
System.Runtime.CompilerServices.RuntimeHelpers does not have a GetHashCode 
method in CF.
