IIS Express or Cassini

Question

I'm a little confused by something. I am using Visual Studio 2010 and am a little unsure whether VS 2010 uses IIS Express or Cassini when running web applications. What is the difference?

Thanks,

Sechin

Answer 1

VS 2010 SP1 supports both IIS Express and Cassini (VS 2010 only supports cassini). You can configure your project to use IIS Express or Cassini.

By default, VS 2010 SP1 uses Cassini and to change the right mouse button on a website / web application and select "use iis express". (When using IIS Express, you will find the IIS Express tray icon and there you will see all the sites that are running)

Answer 2

I think this topic will answer most of your questions. In short:

• If you use Cassini or IIS Express, it depends on the configuration of your project.

• IIS Express has a richer feature set.

Answer 3

I would recommend IIS Express, since I spent 2+ days chasing the bugs that worked fine in Cassini, which now cause ugly heads in IIS Express (and try to publish in IIS7.5). (These are mainly configuration errors for SimpleMembershipProvider)
