I thought that IIS 7.0 and IIS 7.5 have (from the application developer point of view) nearly same features. Then, I found that certain features are not working on IIS 7.0. Are there more features available in IIS 7.5 that are missing in IIS 7.0 (that application developer should know)?

(Maybe not core IIS features, but some other ASP.NET (MVC) features that are working on IIS 7.0.)

  • Do you have any specific problems about your ASP.NET MVC project running under IIS?

  • Yes, I have a problem with plain .cshtml files on IIS 7.0 (check the link in the question). And I also want to know what other features (I may use) are not working on IIS 7.0.
