How to test and debug an app on Surface RT in a hotel room

I wanted to test an app on Surface RT this morning, though I am out of the office with just a Samsung Slate (has Visual Studio), the Surface, and hotel wi-fi.

You can do remote debugging on Surface RT as explained here, however you need a private network.

I set up an ad-hoc network from the Samsung Slate as described here:

Open an elevated command prompt

netsh wlan show drivers

netsh wlan set hostednetwork mode=allow ssid="wireless name" key="password"

netsh wlan start hostednetwork

This allowed me to connect the Surface RT to a private network with the Slate.

Next, I needed to download and install the remote debugging tools for ARM from here.

I ran the remote debugger and was able to connect from Visual Studio on the Slate, but ran into a small issue. I needed a developer license for the Surface, but while on the private network it was not on the internet. When the remote debugger prompted to install a developer license, it could not retrieve it.

The solution was to disconnect, connect to the internet, then install the developer license using PowerShell. Run show-windowsdeveloperlicenseregistration from an elevated PowerShell window.

Then I returned to the private network and was able to launch my beautifully designed test app:

Note that for the actual test I did not run the app attached to Visual Studio. Rather, I deployed in release mode and then ran separately, to avoid the slowdown from the debugger. Once deployed, the test app remains in the Start screen for launching.
