I have an Arcobjects DLL (which has dockable windows etc) written it in Arcgis 9.3.1(Visual Studio 2003 - c# .NET 3.5 ).
Now we are moving to Arcgis 10.0(Visual studio 2010 .NET 4)

What should i consider to copy-paste-code and recompile my DLL in arcgis 10.0?  Like, will my code will work in the same way as it is working with arcgis 9.3.1. Like what are major differences from a programmers point of  view in moving arcobjects applications from 9.3.1 to 10

thanks a lot
