/NoVSIP (devenv.exe)
Disables the Visual Studio SDK developer license key on a developer workstation and then starts Visual Studio.
Devenv /NoVSIP
Remarks
When the Visual Studio SDK developer license is present, all packages are permitted to load, which is necessary for VSPackage development. However, using the /NoVSIP switch directs Visual Studio to load as if the Visual Studio SDK developer license key was not present. This way, only VSPackages that hae a valid package load key are allowed to load. Using this switch allows for testing VSPackage load key authentication.
Example
The following example shows how to use the /NoVSIP switch.
Devenv.exe /novsip
