I have a Web application which has been developed in Visual studio 2005 (.NEt 2.0) . Now i am shifting to Visual Studio 2008. I am not aware what all errors will i get in Visual studio 2008 (.NET 3.5). However i read that Visual Studio 2008 has an option of Choosing the .NET Framework (2.0,3.0,3.5).

Does that imply that any web application which is currenlty having no errors in Visual studio 2005(.NET framework 2.0) will build successfully in Visual studio 2008 if i choose the .NET Freamework as 2.0 or are there any other dependies.
