I'm having trouble with the JavaScript being emitted for client side validation when using Data Annotations on a model. Here's a sample of a model that works just fine with two required fields followed by the JavaScript that's emitted: public class LoginUserViewModel { [Required(ErrorMessage = "Email required")] pub...

I do this: var iFeelLikeIt = true; var items = ["thing1", "thing2",]; if (iFeelLikeIt) { items.push("thing3"); } items....

In C/C++ it would be something like float a = 3.1415; int b = *((int*) and vise-versa int a = 1000; float b = *((float*) In C# you can use the BitConverter ...floatBits...
