I want to get the e-mail address of the user that is currently logged on to Visual studio, in debug mode of course. Just like getting windows account name using Environment.UserName.

is that possible?

    From where? From a Visual Studio extension is reasonable. From any arbitrary program that happens to be debugged by VS is not -- that would cross a process boundary from debuggee to debugger and possibly cause deadlocks, aside from the potential issues for abuse. – Jeroen Mostert Nov 23 '17 at 12:07

I would never use the VisualStudio username for a licensing system. The name of the user of VS is stored in a simple registry key and can be easily manipulated.

You can retrieve the username/account information for the most Visual Studio versions up to 14 (Visual Studio 2015) with the following code. Visual Studio 2017 has a different registry path. Read more about it here.

const byte minVSVersion=11; // Visual Studio 2012
const byte maxVSVersion=14; // Visual Studio 2015

static List<string> getVSUsers()
{
    var vsUsrs=new List<string>();
    for(byte version=minVSVersion; version<=maxVSVersion; version++)
        vsUsrs.Add((string)Registry.GetValue(
            @"HKEY_USERS\.DEFAULT\Software\Microsoft\VisualStudio\"+version+@".0_Config\Registration",
            "UserName", null));

    return vsUsrs.Where(usr => usr!=null).ToList();
}

Unfortunately, it is not possible to determine exactly which VisualStudio version the user used to compile the program.
