Can I install visual c++ 2010 express edition with visual Studio 2010 professional already installed?

I 开发者_开发百科want to do so because intellisense option for clr console application is not working in visual studio 2010..

Yes, you can. They will run side by side.

However, if you have professional installed, wouldn't it be better to update the install and add c++ to it?

There is no Intellisense support for C++/CLI in Visual Studio 2010 (including in SP1 and the Express edition).

I've been using Visual Assist X from Whole Tomato software for the last few weeks and am very happy with their Intellisense support. From the research I did, it appears that theirs is about the best going (Resharper for example does not support C++).

No, this is not going to solve your problem. The IntelliSense parser is exactly the same in the Express edition, it also doesn't support parsing C++/CLI code. You'll need to find the installer for the VS2008 Express edition. That's going to be quite difficult, you cannot get it from Microsoft anymore. Or you'll have to bear and grin it until the next version for Visual Studio, the Microsoft team promised it will be supported again.

Do keep in mind that you are not writing C++ code, C++/CLI is a very distinct language. There isn't much point in writing complete console mode apps in C++/CLI, you might as well use C#. There's an Express edition for that as well, IntelliSense works.
