I'm putting my Q. here instead of the c++ board because this is not a c++ question, but rather a compiler question.
I just installed vc++ 2010 express and the first difference I noticed is that Microsoft removed the Build menu and all its options. Now there is only one Build option under Debug. I miss the Clean option under the old Build menu.
That is the only difference between the two compilers that I have noticed for a Hello World console application. I know there must be others. One link told about MFC, but that isn't an option in Express.
