Kevin Dente ponders on Twitter:
This is something I’ve been meaning to do for a while, as often I’ll open a Web Application in Visual Studio configured to run under IIS and be met with the following:

Running anything elevated is easy, you just need to call ShellExecute (the .NET equivalent is System.Diagnostics.Process.Start) with the “RunAs” verb, so it’s simply a matter of starting Visual Studio’s devenv.exe passing the path to the current solution.
So here goes: copy and paste this into a Macro Module (ALT+F11) then wire up to a toolbar button as appropriate:
Sub ElevateVisualStudio()
Dim slnPath As String = DTE.Solution.FullName
DTE.Solution.Close(True)
Dim startInfo As New System.Diagnostics.ProcessStartInfo(DTE.FullName, slnPath)
startInfo.Verb = "RUNAS"
System.Diagnostics.Process.Start(startInfo)
DTE.Quit()
End Sub
Works On My Machine™, etc and only tested on Visual Studio 2008.
Lots of of people write about this issue but you said really true words!!
