When I want to debug I put break points in Visual studio sources then I goto Build, Attach process menu option in Visual Studio.
I search for w3wp.exe procesess and I found there 3 pieces with different ID. Attach all the 3 processes and start the page to debug.
But I know I should attach 1 of them. How can I see which process I should attach? Where can I find the ID back?
Is it always w3wp.exe? can it be some other processess in some circumstances? e.g. app or webpart or something else
I'm using SharePoint 2013, Visual Studio 2013
