System.Runtime.Remoting.RemotingException "Cannot load type" when c# web app which uses reflection to call a com+ app is moved from w2008R2 to Windows 7 RRS feed

  • Question

  • I am working on a legacy c# web service.  There is a new requirement to use reflection to call a com+ app (an adaptor to connect to a remote web service).   Both the web service and the com+ app have been compiled using VS 2008 on a win7 Ent workstation.  It all works OK when installed on a Windows 2008 R2 server but fails when installed on a Windows 7 Ent PC in a different windows domain, which is where it will need to run for the new environment.  When the function to access the COM+ app is called, a System.Runtime.Remoting.RemotingException is generated with "Cannot load type" referring to the COM+ app name.  The Com+ app works fine on both boxes when called from other applications. 

    It has been suggested that it may be a dotnet version issue,, however both the W2008 and Win 7 boxes have the same dotnet versions installed.

    I would appreciate any insights into how to fix this.
