What differences are between IIS 7.0 and IIS 7.5?

Question

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?

[TN.]

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.

Are you running your application under a Classic Mode App Pool?

[TN.]

No, 4.0 integrated.

Turn on Failed Request Tracing on the IIS and see what you get there.

I was trying to turn of Failed Request Tracing and I have found that I did not have tracing installed. But in the meantime I have found it:) stackoverflow.com/questions/7366925/…
