Web API IIS Requirements

Question

Does the ASP.NET Web API require any particular version of IIS to run? I'm interested in knowing for each version of Web API, e.g. if Web API 2.0 requires IIS7.5 and Web API 2.1 requires IIS8 for instance. I can't seem to find this information anywhere.

Answer 1

ASP.NET Web API is part of ASP.NET stack, and therefore is supported on all IIS releases if the targeting .NET Framework is supported also on that Windows version.

• First release of ASP.NET Web API (version 4.0.20710) and its patched version (4.0.30506) requires .NET 4, which covers all Windows versions starting from Windows XP. That means IIS 5.1 and above should support this release of Web API.
• Second release, called ASP.NET Web API 2 (version 5.0.0), and above (aka 2.1 and 2.2) requires .NET 4.5, which covers all Windows versions starting from Windows Vista. That means IIS 7.0 and above should support ASP.NET Web API 2.*.
