Deploy asp.net mvc beta to iis 6 causing 404's

Question

I'm struggling to get around the 404 errors from asp.net mvc beta when deploying on IIS 6. I had this working in one of the previews by mapping .mvc in IIS but this no longer works. I've read Omar's post and several others on the web and tried their solutions but no luck so far.

The home page opens without a problem on IIS 6 but others 404 and the site runs well on IIS 7.

Has anybody deployed asp.net mvc beta to IIS 6 with success? If so, what adjustments did you need to make to the code and/or IIS settings to get it to work?

Answer 1

I found a solution to my problem from Steve Sanderson's blog (Thanks Steve):

Use a wildcard mapping for aspnet_isapi.dll. This tells IIS 6 to process all requests using ASP.NET, so routing is always invoked, and there’s no problem. It’s dead easy to set up:

• open IIS manager (run -> inetmgr -> OK)
• right-click your app, go to Properties
• then Home Directory tab, then click Configuration.
• Under Wildcard application maps, click Insert (not Add, which is confusingly just above)
• then enter C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll for “Executable”, and uncheck Verify that file exists.

I can't seem to write comments yet. So I'll write a new answer.

There are a few similar questions going around on stackoverflow. I'm using MVC 3. I know the question was MVC 2 related. But since this is the first stackoverflow post I bumped in to, I think it's worth mentioning that:

• when you use MVC 3, you need to add a new extension mapping with the executable of the .NET 4 framework (C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll)

<edit>I just found out that I even don't need to set up the extension mapping. </edit>

• It still didn't work for me then :) I still had to 'Allow' ASP.NET v4.0.30319 in the Web Service Extensions section in IIS:
  • open IIS
  • click on the server node
  • open the Web Service Extensions section
  • select the ASP.NET v4.0....
  • right click --> Allow Good to go!

Url rewriting can help you to solve the problem. I've implemented solution allowing to deploy MVC application at any IIS version even when virtual hosting is used. http://www.codeproject.com/KB/aspnet/iis-aspnet-url-rewriting.aspx
