Hi,
I have been using Microsoft ASP.NET Web API version 1 (http://www.asp.net/web-api) with great success in one of our applications hosted on UltiDev Web Server Pro.
After upgrading to ASP.NET Web API 2.1 we are receiving the following error message:
This operation requires IIS version 7.5 or higher running in integrated pipeline mode.
While I realize that this is in fact Microsoft that causes this behaviour, I was curious whether someone else have had the same problems. What's your approach on this? Are there any known workarounds?
