For windows apps  forms and console  I use this   Add a reference to System Windows Forms in VS then   using System Windows Forms  namespace whatever       class Program               static string ApplicationName   Application ProductName ToString            static void Main string   args                                                     This works correctly for me whether I am running the actual executable or debugging within VS   Note that it returns the application name without the extension   John

You can use Environment GetCommandLineArgs   to obtain the arguments and Environment CommandLine to obtain the actual command line as entered   Also  you can use Assembly GetEntryAssembly   or Process GetCurrentProcess     However  when debugging  you should be careful as this final example may give your debugger s executable name  depending on how you attach the debugger  rather than your executable  as may the other examples

If you need the Program name to set up a firewall rule  use   System Diagnostics Process GetCurrentProcess   MainModule FileName   This will ensure that the name is correct both when debugging in VisualStudio and when running the app directly in windows

System AppDomain CurrentDomain FriendlyName - Returns the filename with extension  e g  MyApp exe      System Diagnostics Process GetCurrentProcess   ProcessName - Returns the filename without extension  e g  MyApp    System Diagnostics Process GetCurrentProcess   MainModule FileName - Returns the full path and filename  e g  C  Examples Processes MyApp exe    You could then pass this into System IO Path GetFileName   or System IO Path GetFileNameWithoutExtension   to achieve the same results as the above

Try this  System Reflection Assembly GetExecutingAssembly    This returns you a System Reflection Assembly instance that has all the data you could ever want to know about the current application   I think that the Location property might get what you are after specifically

On  Net Core  or Mono   most of the answers won t apply when the binary defining the process is the runtime binary of Mono or  Net Core  dotnet  and not your actual application you re interested in  In that case  use this   var myName   Path GetFileNameWithoutExtension System Reflection Assembly GetEntryAssembly   Location

IF you are looking for the full path information of your executable  the reliable way to do it is to use the following      var executable   System Diagnostics Process GetCurrentProcess   MainModule                         FileName Replace   vshost          This eliminates any issues with intermediary dlls  vshost  etc
