IIS and server OS requirements for ASP.NET 4

Question

This only indicates the requirements for customers: http://msdn.microsoft.com/en-us/library/8z6watww%28v=VS.100%29.aspx

I am looking for similar documentation as a reference not only for .NET 4, but also for ASP.NET 4, and for which IIS, OS SP, etc. are needed. I would like to know if there are any problems with requesting IT professionals to install ASP.NET 4 and MVC 3 on our server. I do not want to have an egg on my face :)

Additional Server Requirements Installation

If you need to run the setup server, your computer must have the following software in addition to the basic requirements:

• Internet Information Services (IIS) version 6.0 or later. To access ASP.NET features, IIS with the latest security updates must be installed before the .NET Framework is installed. ASP.NET is only supported on Windows XP Professional, Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2.

So, it will work in IIS 6.0 or higher. If you want to know which operating systems support asp.net 4.0, it will be any operating system that supports IIS version 6.0 or higher. These are jives with my comment on your question.

However, the most important thing is to ensure that you need to configure any IIS.NET 4.0 application to use a different application pool than 2.0, 3.0, or 3.5. There is more information about this here: http://johan.driessen.se/posts/getting-an-asp.net-4-application-to-work-on-iis6

Answer 2

WinXP has IIS 5, and it supports the .NET Framework and ASP.NET 4. For server technologies, IIS6 and later are supported, since Server 2003 with IIS6 is the oldest server technology that supports ASP.NET 4.
