If you must have strongly typed result I would deserialize Profile as a dictionary of superposition of properties
class AbscdeClass
{
public string A { get; set; }
public string B { get; set; }
public string C { get; set; }
public string D { get; set; }
public string E { get; set; }
}
class JsonBody
{
public Dictionary<string, AbscdeClass> Profile { get; set; }
}
and parse original JSON text as
JsonBody json = JsonConvert.DeserializeObject<JsonBody>(jsonString);
