We have a web application built using Visual Studio 2003 and is currently running .net 2.0. We are planning to upgrade the application. However, the webserver it is hosted on runs Windows Server 2003.
According to this link http://msdn.microsoft.com/en-us/library/bb822049(v=vs.110).aspx
Windows Server 2003 is compatible with .NET 4.0.
Does this mean I should upgrade to .NET 4.0 (Visual Studio 2010) and should NOT go to .NET 4.5 (Visual Studio 2012)?
I have approval to upgrade the web application but we have not talked about upgrading the web server operating system. Can you please advise?
