Question

Using ASP.NET MVC 4 Web API

public IEnumerable<Item> GetAll(GetItemRequest request) {

This throws an error, Object reference not set to an instance of an object., where request is null.

public IEnumerable<Item> GetAll(int itemId) {

This works just fine, where itemId is non-null.

GetItemRequest model has a single property, public int itemId { get; set; }

What am I missing?

Try this:

public IEnumerable<Item> GetAll([FromUri] GetItemRequest request) {
