Answer 1

From the picture where you can actually see that data is available (there are rows) I am strongly suspecting that you're using a CamelCasePropertyNamesContractResolver on the ASP side of the application. That means even though your property names in C# will start with a capital letter, the returned JSON uses camel case (starting with a lower case letter)
