Linq Query with byte[] Constant

[oliverw]

The following method will crash with an NotSupportedException("The constant for 'byte[]' is not supported") thrown at MongoQueryTranslator.cs:699. Any chance to get this to work or is this a limitation of MongoDb or BSON?

public Guid? GetUserIdByUsernamePassword(string Username, byte[] Password)
{
using (var db = ServiceLocator.Get())
{
var users = db.GetCollection();
var user = users.AsQueryable().Where(x => x.Username == Username && x.Password == Password).FirstOrDefault();

    if (user == null)
        return null;

    return user.Id;
}

}
