Ok so when debugging, for example when i set my breakpoint on simple string declaration 

string a;

and then pressing f11 (step into) my debugger steps into xstring file, and i don't want it. I want it to step into JUST MY code, it works fine with C# tho.

I have "Just My Code" enabled and i don't know what to do. I just dont want it to step in not my files.

The C# feature you are referring to is called "Just My Code". Unfortunately, Visual Studio does not implement it in the same way for C++. As documentation says:

C++ Just My Code is different than .NET Framework and JavaScript Just My Code because the stepping behavior is independent of the call stack behavior.

There is a workaround, however:

You can create your own .natstepfilter and .natjmc to customize the stepping and call stack window behavior in the %USERPROFILE%\My Documents\Visual Studio 2015\Visualizers.

Despite of the typo in the documentation ("2015") and the horribly convoluted way this was designed, the trick actually works!

For example, with the Visual Studio 2017 installation on my machine, I can go to C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\Packages\Debugger\Visualizers and a add file called .natstepfilter with the following content:

<?xml version="1.0" encoding="utf-8"?>  
<StepFilter xmlns="http://schemas.microsoft.com/vstudio/debugger/natstepfilter/2010">  
    <Function>  
        <Name>std::.*</Name>  
        <Action>NoStepInto</Action>  
    </Function>  
</StepFilter>

Now when I debug in Visual Studio and step into something, all C++ standard-library functions are skipped.

Note that the actual format of the XML file is not validated very strictly by Visual Studio. I've actually used the simpler form explained in the Visual Studio 2015 documentation.
