No IntelliSense for C++/CLI in Visual Studio 2010?

Solution 1:

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:

Unfortunately in this release we had to cut the intellisense support for C++/CLI due to time constraints. If you want to get some intellisense like quick info and memberlist on the native classes you can get it by choosing no /clr support in the project properties.

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.

Solution 2:

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.

Solution 3:

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.
