Could not load file or assembly Microsoft.VisualStudio.Enterprise.ASPNetHelper RRS feed

  • Question

  • I'm trying to enable asp.net profiling on a handler I've created. I've adeed the relevant bits to my web.config but it cannot start up due to the below exception:

     Could not load file or assembly 'Microsoft.VisualStudio.Enterprise.ASPNetHelper, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

    I've confirmed that the dll referenced is in the Visual Studio 9.0 Private Assemblies folder so I'm unsure why it is not picking it up. This is a VS development server launched from VS.

    This is what I've added to my web.config to enable the profiling


        <assemblyIdentify name="Microsoft.VisualStudio.Enterprise.ASPNetHelper" publicKeyToken="b03f5f7f11d50a3a" culture="Neutral"/>
        <codebase version="" href="C:/Program Files (x86)/Microsoft Visual Studio 9.0/Common7/IDE/PrivateAssemblies/Microsoft.VisualStudio.Enterprise.ASPNetHelper.DLL"/>
    		<add key="Microsoft.VisualStudio.Enterprise.AspNetHelper.VsInstrLocation" value="C:\Program Files (x86)\Microsoft Visual Studio 9.0\Team Tools\Performance Tools\VSInstr.Exe"/>
