What is the difference between these 2 JSON formats?

I have the following simple class:

public class Test
{
    public string property1 { get; set; }
    public string property2 { get; set; }
}

When I try to serialize it into JSON using:

Test t = new Test() { property1 = "p1", property2 = "p2" };
var serializedData = JsonConvert.SerializeObject(t, Formatting.None);

I get JSON that looks like the following:

This will come across as null when I try to submit it to a WEB API app. I am using the application/json in the content header.

If I instead submit the same class starting off as a string, it works fine:

string test = "{\"property1\":\"p1\",\"property2\":\"p2\"}";
var serializedData = JsonConvert.SerializeObject(test, Formatting.None);

But it looks like this in the Visualizer:

If I paste both strings into Notepad, they look exactly the same.

Any ideas why the class serialization doesn't work?

The JSON serialization works fine. In the first case when you're serializing the object it returns you normal JSON: 

{
    "property1": "p1",
    "property2": "p2"
}

In the second case you have already serialized the JSON by hand and you're trying to serialize it second time which is resulting in a new JSON containing a JSON itself as single value or more likely single key: 

{ "{\"property1\":\"p1\",\"property2\":\"p2\"}" }

You can test that the second string is already serialized by running this code: 

var serializedData2 = JsonConvert.DeserializeObject(test);

And it should return you the key-values of the JSON: 

{
    "property1": "p1",
    "property2": "p2"
}

I guess the null value is coming from somewhere else.
