IIS 7 + ASP.NET 4
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:
Error Summary
HTTP Error 500.21 - Internal Server Error Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module listMost 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.
I have the same problem when try publishing SL App using VS2010 although there is no prob before with .NET 3.5SP1 and VS2008.
So try run this (%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i) as described here forums.iis.net/t/1149449.aspx and here www.gotknowhow.com/articles/fix-bad-module-managedpipelinehandler-in-iis7 and It works now. So the problem is ASp>NET 4.0 has not properly installed, huuu... :)
the "aspnet_regiis.exe -i" trick worked for me.
