Description Eric Beisecker 2012-02-29 17:27:04 UTC
Scenario: After compiling and deploying to an iOS device, if the MonoTouch application is removed from the iOS device, the next time a user clicks 'Run' or 'Debug' in MonoDevelop the application is NOT launched and the message 'Could not find application 'AppName' on device 'DeviceName' is shown in the Application Output.

If the application is not on the device MonoTouch should redeploy it.

1. Build / Deploy a MonoTouch app to an iOS Device
2. Remove the application from the iOS device
3. Click 'Run' or 'Debug' to re-launch the application on the Device. 

Monotouch: 5.2.6

Uploading can be quite slow, so this would hurt the experience for most users. We can't do this unless mtouch can detect and report whether the app is on the device.
Comment 2 Rolf Bjarne Kvinge [MSFT] 2012-03-14 09:55:41 UTC
mtouch can now check if an app is installed.

mtouch --isappinstalled bundleId

returns 0 if installed, 1 if not.
Comment 3 Miguel de Icaza [MSFT] 2012-04-24 12:26:09 UTC
Probing if the app is installed is also slow.

On my machine, on first run it takes about 5 seconds to start.

On warm setups, it takes 1.29 seconds.

What I suggest is that we make it so that we proceed with the execution path as we have it now, and if we fail, only then we probe for the app being there, if it is, we report the problem to the user.   Otherwise, we upload, and retry the process.

At least in this way, not everyone has to pay the 1.2 seconds to probe on cold/ warm starts,
