Object browser not working for c++ in VS 2015 community

Question

For some reason I just can't get the Object browser to pick up my function/class documentation in Visual Studio 2015 Community.

I have tried as described here XML Documentation (Visual C++).

The functions appear in the Object browser, but none of the documentation. For example,

/// <summary>Executes the TSQL-statement on the current DB connection.</summary>
/// <param name="query">The TSQL-statement to execute.</param>
void executeSqlStmt(const std::string& query);

This shows up in the Object Browser as

Am I missing some configuration? I have set the generate documentation setting to "No", because currently I am not interested in generating .xml files, but only to view the function documentation in the IDE as Intellisense help.

Thank you.
