title: Strange error while attempting to use Zip task from .net 4.0 version of MSBuild.ExtensionPack
body: <p>We've been getting inconsistent results from the Zip task in Tigris MSBuild task library, so we're trying to use the Zip task in the MSBuild.ExtensionPack for .NET 4.0.  But when we execute this new Zip task, we get the following error from the MSBuild executable:</p>
  
  <blockquote>
    <p>C:\development\build\PrepareLastKnownGood.csproj(40,3): error : Typ
    eInitializationException: The type initializer for 'java.lang.System' threw an
    exception.\r
    C:\development\build\PrepareLastKnownGood.csproj(40,3): error : Unsat
    isfiedLinkError: Unable to load DLL 'vjsnativ': The specified module could not
    be found. (Exception from HRESULT: 0x8007007E)\r</p>
  </blockquote>
  
  <p>Has anyone else encountered this error in their use of the Zip task from MSBuild.ExtensionPack?  If so, how did you resolve it?</p>
