С# Json to custom class

I have json :

[
     {
        "Name" : "SHA of timestamp",
        "ProjectURL" : "URL to Proj",
        "AccountIdentifier" : "Account Identifier",
        "Repositories":
        {
            "GitLink1": 
            {
                "Login" : "login1",
                "Password"  : "pas1"
            },
            "GitLink2": 
            {
                "Login" : "login2",
                "Password"  : "pas2"
            },  

            ...

            "GitLink999":
            {
                "Login" : "login999",
                "Password" : "pass999"
            }
        }
    },

    ...

    {
        Same entry
    }
]

I need to fill it in IEnumerable of my created classes

public class Git
{
    public string Login { get; set; }
    public string Password { get; set; }
}

public class Repositories
{
    public Git git { get; set; }
}

public class ConfigEntry
{
    public string Name { get; set; }
    public string ProjectURL { get; set; }
    public string AccountIdentifier { get; set; }
    public Repositories Repositories { get; set; }
}

Using

IEnumerable<ConfigurationEntry> config = JsonConvert.DeserializeObject<IEnumerable<ConfigurationEntry>>(CONFIGJSON);

Where CONFIGJSON contains frst json file.

Gives me this data of ConfigEntry class :

Name : "filled with some data"

ProjectURL : same

AccountIdentifier : same

Repositories : NULL

How i can fill Repositories field with all data i have in config JSON?

Is there any ideas.
