I tried to do the "Hello World" app with Xamarin.Forms under Visual Studio and when I run a build (without debugging) I get a message from Visual Studio stating "Please select a valid device before running the application."
I have followed the instructions for installation and also did the following:
-Selected the MonoForAndroid_* choice under unsupported devices and then launched the appropriate Emulator.
-Made sure my Android file paths are correct.
-Assured my Build Settings match my Android settings for Release/Debug, etc.
When I reviewed the documentation it seems I should be getting a dialogue asking me to select a device - but that never appears.
Any thoughts? What is the newbie stupid mistake I am making?
Thank you in advance for your help.
