I've just swapped our project from ASP .Net Core 1.0.0-rc2-final to 1.0.0. Our website and client have stopped working because of the capitalization of JSON properties. For example, this line of JavaScript now fails
for (var i = 0; i < collection.Items.length; i++){
because the controller now calls the array "items" instead of "Items". I have made no changes beyond installing the updated packages and editing the project.json file. I have not changed the C# model files which still capitalize their properties.
Why have the ASP.Net Core controllers started returning JSON with lower-cased properties? How do I go back to them honoring the case of the property names from the model?
MVC now serializes JSON with camel case names by default
Use this code to avoid camel case names by default
services.AddMvc()
.AddJsonOptions(options => options.SerializerSettings.ContractResolver = new DefaultContractResolver());
