aspx finding multiple ReportViewers in GAC RRS feed

  • Question

  • I've been researching and trying different solutions for the past day now, and I can't figure out why this is happening.  Everything works great on my local computer, and I have 4 different versions of ReportViewer registered in the GAC.  When I move my code to our production server, which has 2 versions of ReportViewer registered in the GAC, it says that both exists.  This is a C# Web Application that I'm validating against HTML5, and I do have Microsoft.ReportViewer.WebForms in my References.  Below is my relevant code:

    Web.Config - I completely removed all references of ReportViewer from the config file and started over to make sure there were no duplicate entries or multiple versions.  Currently, I have no mentions to any version of ReportViewer in my config file, and everything is continuing to run great on my local machine.  However, just to try different things, I've tried adding the appropriorate tags for Version 10.0 (the version I'm wishing to use) in the following areas:  AssemblyBinding, BuildProviders, and I believe RoleManager.  None of them affected the code locally, and continued to produce the same error (below) on our production server.

    In my .aspx file, I have the following relevant code...and this is where the error seems to be happening.  Below in the screenshot of the error, it's pointing to the rsweb reference and saying there are 2 suitable versions in the GAC:

    So why, why, why is it ignoring my registry at the top of the page?
