.NET framework issue stopping the application in getting logged in RRS feed

  • Question

  • We have an application hosted in IIS 7.5 on a Windows 2008 server [X64].

    We are unable to access the application. When ever we try to access the appplication the application is blocking us in getting logged in. In the event viewer we have noticed that a warning is pointed in the application events stating that there is an issue with the .NET framework 4.0 below is the warning message we observed in the event viewer for your reference,

    Exception type: HttpException Exception message: The assembly 'C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\root\13fb82de\1eafa268\App_LocalResources.root.dll' is already loaded in another appdomain. Setting in machine.config can help solve this issue.

    We tried making the above mentioned change in machine.config with no reolution. Would appreciate any quick help around this issue.

  • Hi Pradeep.vajjala,

    This is not the right forum for your issue, this forum topic is "Discuss and ask questions about the setup and deployment of .NET Framework". Based on your description, the dll is loaded in another appdomain and you may need to check what app is loading your dll which makes you not able to access your application. Or doing something else to fix this issue, however, this is not related to .NET Framework Setup.

    I think your .NET Framework installed without problem on your OS. If you are not sure of this, try this tool to verify its installation.

    If the result also shows .NET installed without problem, please reopen a new post on your application technology forum. For example, if your application is a web application, post on ASP.NET forum

    By the way, I just found some related workaround which may helps on this issue:
