I am compiling a site that references the FreeTextBox.dll. When I had the site running under windows server 2003 it was fine and would compile through visual studio without a problem. I moved the website to Server 2008 and now the site will not compile through visual studio, but it will run in the browser fine. I do not understand how IIS can complie the site at runtime without and error, but Visual Studio will not. The error that I get when compiling is Unknown server tag 'FTB:FreeTextBox'. I have made sure the dll is in the Bin directory. I am not sure what to do. I think it has something todo with Server 2008 becasue it compiles fine under server 2003.
I am using Visual Studio Professional 2008 and the code is written in C#.
Any help would be greatly appericated.
