Compiled and installed Mono trunk (revision 152934) on Windows 7 using cygwin,
with .NET 4.0 profile enabled. Running an EXE compiled for Microsoft .NET 4.0
(using VS 2010 RC) with mono.exe returns a 'runtime version not supported'
error, as given below.

Reproducible: Always

Steps to Reproduce:
1. Compile .NET 4.0 assembly (EXE) for .NET 4.0 RC using VS 2010 RC.
2. Run "C:\cygwin\mono\build\bin\mono.exe MarkovChainTextBox.exe" from the
command line (cmd.exe). MarkovChainTextBox.exe is the file name of the .NET 4.0
EXE to run, and is a simple command-line program.
3. Observe error message returned.
Actual Results:  
Error message:

WARNING: The runtime version supported by this application is unavailable.
Using default runtime: v2.0.50727

** (MarkovChainTextBox.exe:4008): WARNING **: The class System.Func`2 could not
be loaded, used in mscorlib, Version=, Culture=neutral,

Unhandled Exception: System.TypeLoadException: Could not load type
extBox.Program' from assembly 'MarkovChainTextBox, Version=,
neutral, PublicKeyToken=null'.

Expected Results:  
Program should run without problems using .NET 4.0 CLR and class library.
