I have an ASP.NET application that I am trying to convert to an ASP.NET 4 application. The application is fairly simple. I have created a new web application in IIS 7.5 pointing to the directory that the ASP.NET application exists in.
When I attempt to execute the application, but entering http://localhost:[port] into my browser, I receive the following error:
HTTP Error 500.21 - Internal Server Error Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list
Most likely causes:
- Managed handler is used; however, ASP.NET is not installed or is not installed completely.
- There is a typographical error in the configuration for the handler module list.
