Windows Phone 7 Developer Tools RTM Problem

I couldn’t get Windows Phone 7 Tools RTM to work, whenever i try to deploy the application i receive the following error

“Connection failed because of invalid command-line arguments.”

this long thread which comes on the top of the search results has the solution buried among all the replies

the problem was that the Virtual Machine Manager (VMM) service used by the Windows Phone Emulator was not running. you can query the status of the VMM service from command window by typing the command “sc query vmm”, if the service is stopped, start it by the following command (run the command window as administrator) “sc start vmm”.

Thanks god :), this version of the emulator is faster than the previous ones.

Here is a screenshot of a default Windows Phone Panorama Application
