As a C# Programmer is C++/CLI a good step? [on hold]

I am a good C# programmer, but recently i had a work involving a lot of pinvoking so i thought it would be a good idea to learn C++ through C++/CLI as it is an intermediate language between both Native/Managed worlds, also i like the fact that in C++ i have access to the well detailed .Net Framework. HOWEVER from the results of the search i done C++/CLI seems to be a neglected language with no much support so i thought what should be a good decision for me now regarding that i am a former C# programmer who want to dive a little bit into the Native world.

Edit: i know that this question is partially asked times in the past, but i want to get a more 2015-ish answer.
