Question

I want when I run app by Visual Studio (F5 key), variable is_vshost have have value true, and if I rebuild app and open it directly in Windows Explorer, it have value false. How I can do that? Thank!

Answer 1

You can check the value of

System.Diagnostics.Process.GetCurrentProcess().ProcessName

It should be devenv.exe when running from within VS.

Answer 2

In code, you can check to see if the vshosts.exe is running by looking at the CurrentDomain.FriendlyName. If it ends in ".vshosts.exe" then it's running.

    bool is_vshost = false;
    int i = AppDomain.CurrentDomain.FriendlyName.IndexOf(".");
    string s = AppDomain.CurrentDomain.FriendlyName.Substring(i);
    if (s == ".vshosts.exe")
        is_vshost = true;
