I just moved from Visual Studio 2008 to Visual Studio 2010 (final) and noticed one major flaw:
When I try to use AutoComplete in a C++ source file for managed C++, a small note in the footer appears:
IntelliSense for C++/CLI is not available
Uh, has IntelliSense for C++/CLI been dropped from Visual Studio 2010? Is there any way to get this back? It is rather useful...
According to the Visual C++ Team Blog, C++/CLI Intellisense will be in the next version of Visual Studio, but not in a service pack for VS2010. That blog post also gives some detail as to what went wrong and led to this sad state.
I don't know if you can use this settings but it work for me. I only check the Common Language RunTime Support for the cpp files that use it. I do not check it for the whole project and I've got intellisense for all the files that don't use the CLI.
If you want to get IntelliSense back, install Visual Assist X from Whole Tomato Software. Here you can get a 30-days trial to check the intellisense.
This solution is only if you don't want Common Language Runtime
It worked for me in VS2010
Go to Project Propreties > Configuration Properties > General > Common Language Runtime Support and set it to No Common Language Runtime Support. This will work fine just after hitting Apply button.
You are correct. Unfortunately it has been dropped. You can check this opened issue on Microsoft's Connect website.
I'll just quote them for the sake of the answer:
About getting back intellisense, your best chances for now are using third-party tools like VA Assist for example. I've tried it with Visual Studio 2008 and its IntelliSense is a whole lot better than the default one.
It is available again in Visual Studio 2012.
As mentioned you could install some paid software such as "Visual Assist X from Whole Tomato Software".
or
You could use open source tools that contain intellisense*, one such tool is Qt Creator 3.3.1 (opensource). You have two options, either setup your entire project with Qt to compile using VS2010 compiler, or use Qt to link to your source files and compile with VS2010. You write your code in Qt, save, flip windows to vs2010 and compile and debug.
When changes are saved in Qt, vs2010 will automatically reload the source file in the project and you can compile.
