RestartToCursorCommand.cs

// This is "restart to cursor", a complement to VS's "run to cursor" which will first restart (and recompile if you have
// it set up like that) the currently running program (if any) and then execute the "run to cursor" command.
// To make an extension on your own, create a C# VSIX template, then Add Item -> Extensibility -> Command and replace the
// file with the contents of this Gist. I bind it to Ctrl-Shift-F10 since Ctrl-F10 is "run to cursor".
