Indicator in external DLL

[ren37]

Hello

I'm developing some indicators using C# MS Visual Studio 2015.
All indicators placed in external dll for licensing and security reasons.
I'm using some namespace different from NinjaTrader.Indicator

namespace MyNamespace
{
    public class MyIndicator: Indicator
    {
              ....
    }

    public partial class Indicator : NinjaTrader.Indicator.IndicatorBase
    {
              // here is code from NT7 wizard template
                ....
    }
}

My dll is in Ninja Script assemblies (just copied it in \Custom and restart NT7).
But I dont see my indicator in Indicators list.

Indicator works fine.
It was AnyHotKey script error.
