I'm having a problem getting a breakpoint to occur in library header file. The normal library is under Arduino. 

Using VS2017 and Industruino board.

Here are the steps I've taken:
1) copied the file of interest locally into project
2) made #include reference to it using ""
3) performed (added existing) reference to .h file (contain actual code) using solution explorer. 
4) renamed original file in library under arduino lib structure

I know the local file is being used since adding a syntax error to it causes a compiler error. Using "Goto Definition" pulls up the local file as well.
When using the project explorer (under explorer, file set to ALL), I can see the routine where the breakpoint is set. The path to the file is "not" a link but contains full path.The project compiles and runs just does not break.

Does VM support pulling a file of interest into a project to allow debug? This library is huge and covers numerous devices,etc. Each calls other arduino structured using libraries <>.

On simple libs, I've pulled all files locally and got breakpoint to work using a source,header reference in explorer along with an #include. 

What am I doing wrong?

Thanks

I've attached the .h file which contains the class [bool BlynkProtocol<Transp>::run(bool avail), line 129] where I'm trying to break at. How can I break within the class? 

This is structured different than I'm familiar with. Normally the .h has the class and definitions for vars,functions ect. Then .cpp uses scope resolution. In that case, the function is in the .cpp file and references the class i.e. class::function_name

Any suggestions?

Tim,

thanks for confirming I'm not missing something AND thank you for considering it in future releases.

I did use serial.println() and it works BUT, hey, you spooled us with breakpoints...
