Accepted answer
The problem was indeed within the method GetCollection<>() once I replaced it with the following code, it worked just fine:
public MongoCollection<T> GetCollection<T>(string name = null)
{
string collectionName = name;
if (collectionName == null)
collectionName = typeof(T).Name;
if (Database.CollectionExists(collectionName) == false)
Database.CreateCollection(collectionName);
return Database.GetCollection<T>(collectionName);
}

You can also change it to something like
var usr = users.AsQueryable().Where(u => u.UserName.Equals(username)).FirstOrDefault();
