Build Failed. MonoDroid does not support running the previous version

mvvmcross, visual-studio-2012, xamarin, xamarin.android

Solution

Found the problem, i needed to set my startup project to the android app. I could slap myself, i didn't pay attention to it cause for WP8 it's not needed. Took me a day and half to solve this :-( Once again this proofs that error messages are not always clear in what they mean or say.

Problem

This is my first Xamarin android project with MVVMCross. Started from scratch. The project builds without any errors but when i try to debug it, i get a build failed: MonoDroid does not support running the previous version. Please ensure your solution builds before running or debugging it. Build output says: 1>------ Deploy started: Project: Mobile.Droid, Configuration: Debug Any CPU ------ 1>Error: The operation could not be completed ========== Deploy: 0 succeeded, 1 failed, 0 skipped ========== Ide.log: ERROR [2014-02-05 16:08:08Z]: Could not update jumplists System.InvalidOperationException: The file type is not registered with this application. at Microsoft.WindowsAPICodePack.Taskbar.JumpList.AppendCustomCategories() at Microsoft.WindowsAPICodePack.Taskbar.JumpList.Refresh() at MonoDevelop.Platform.JumpList.UpdateJumpList() at MonoDevelop.Platform.JumpList.OnUpdateTimerEllapsed(Object sender, EventArgs args) I'm using Visual Studio 2012 (Update 4) Windows 8 Xamarin Studio 4.2.2 Xamarin.Android 4.10.02014 Please help me cause i already spent a day trying to solve this issue.
