HTTP Error 404.17 - Not Found
Problem
You get this error when first trying to run your application
HTTP Error 404.17 - Not Found
The requested content appears to be script and will not be served by the static file handler.
Most likely causes:
1. This can also be caused when Microsoft .NET Framework is not registered properly with Microsoft IIS.
2. The request matched a wildcard mime map. The request is mapped to the static file handler. If there were different pre-conditions, the request will map to a different handler.
Solution
1. Reregister ASP.NET with IIS by selecting Build, Re-register ASP.NET with IIS.
2. If you want to serve this content as a static file, add an explicit MIME map.
