It will run once and then it won't run with the error. Reboot the PC? Double check the XAML of that page? If there is an issue in the XAML, that gets generated to code when you compile If that generated code is screwed up then the partial class that is the code-behind would probably get squirrely. Don't know what to tell ya in that case. Its not systemic with Xamarin in general or everyone would be seeing the same thing. ClintStLaurent thanks. I hope Xamarin team gives some clear instruction.

Clear instruction For what? You've got some bad code or markup someplace. Its a problem specific either to your installation or your solution: Not to everyone. So there's little anyone can tell you based on "I get an error". Start with a new solution. Build it 10 times.

I have no web. This causes an error for me too. You need a reference to the WebMatrix. Data namespace:. That will import the Database class so you can use it without fully-qualifying the name. It's not clear why you think you wouldn't need any "imports" by which I assume you mean using directives like the one above but if this is in a plain C file, then you certainly do need them or you need to fully-qualify type names, which is ugly.

Data, but the commenters don't tell you how to fix the problem. Here's how:. If you're not sure where to get it, you can have WebMatrix create a new project using a database-enabled template -- say, Bakery -- and get it out of that project's bin folder. Or you can search your hard drive for the file. This is kind of a bad idea for a site you're going to have to maintain for a long time, but for the purposes of this demo, you just need to add using WebMatrix.
