Possible Reason for this
issue:

Based
on investigation what we found is that the problem is caused by a known issue with
Visual Studio 2010 RTM base libraries.


Solution:

The
above problem is fixed in Visual Studio 2010 SP1. Please install Visual
Studio 2010 SP1 (VS1010 SP1) and recompile the Windows Azure Application.  After it you can test Worker Role in
development fabric and Windows Azure.
