I have a problem with an ASP.NET MVC site.
These are the details:
Whenever I make a request for the app I get the "HTTP Error 404.0 - Not Found"-error and the detailed error information shows it is the static file handler that reports the error:
meaning that the request never entered the MVC stack.
I should note that the IIS already serves a ASP.NET MVC 3 on the same app pool and a MVC 2 on a ASP.ENT 2 app pool. So it's the combo ASP.NET 2 on the ASP.NET 4 app pool that are giving me headaches.
Basically I want to upgrade the app from ASP.NET MVC 2 on a ASP.NET 2.0 app pool to a ASP.NET MVC 2 on a ASP.NET 4.0 app pool.
So any ideas?
I see you fixed your issue, but for anyone googling:
I had this issue and in my case I just needed to register ASP.NET 4 with IIS. I was deleting and re-adding webs to fix other issues and simply forgot to do that. The command that worked for me was:
Your own .net version may be different, especially if you are in the future, so the above path may not be exactly right.
I had the same problem when I installed IIS after installing Visual Studio, etc.
I was able to fix the problem by changing my Web.config file, adding the
runAllManagedModulesForAllRequests="true" to the
<system.webServer> <modules runAllManagedModulesForAllRequests="true"> ... </modules> </system.webServer>

Chris' answer got me to check whether the app pool was actually configured for .net 4. Sure enough, this server defaults to creating 32-bit .net 2 pools in classic mode.
Ensure that your app is using 4.0 and you'll probably want Integrated pipeline for all new development. 32/64 is mainly up to your dependencies. The default is leaving "allow 32 bit allocations" set to false.
In my case, a similar error was thrown because
StaticFile Handler was disabled / not working properly. I eventually fixed it by removing the handler and re-adding it through the
web.config. Also, in case of a
403.3 error, change the
RequireAccess-property value from "Write" to "Read"
<configuration> <system.webServer> <handlers> <remove name="StaticFile" <add name="StaticFile" path="*" verb="*" modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" resourceType="Either" requireAccess="Read" /> </handlers> </system.webServer> </configuration>
