Add some sort of interface to a Dynamic.ExpandoObject object

Question

I am using a library that return a IList<dynamic> (from a jsonArray), dynamic means not having any intellisense while using such object, I would like to be able to simply define what the dynamic object contains.

Let's say you're calling some https://dummy-url.com/something endpoint which returns the following JSON:

[
    {
        "firstProp": "First value",
        "secondProp": "Second value",
        "intProp": 1337
    },
    {
        "firstProp": "Another first value",
        "secondProp": "Another second value",
        "intProp": 42
    }
]

You would then need to define a class in your program representing that JSON structure, such as:

public class Something
{
    public string FirstProp { get; set; }
    public string SecondProp { get; set; }
    public int IntProp { get; set; }
}

Finally, call that endpoint and deserialize its result to the object defined by your class:

public async IList<Something> FetchListOfSomething()
{
    var url = "https://dummy-url.com/something";
    return await url.GetJsonAsync<List<Something>>();
}
