Unable to load custom assembly

[carmiFR]

I am trying to add to nt8 8.0.12.0 64-bit my own c# 4.5.0 dll compiled as AnyCpu with visual studio 2017 but it fails with messages (see attached image) : "Unable to load custom assembly: The given key was not present in dictionary". Of course then, the dynamic loading failed.

The way i proceed :

1. I create a strategy called "Bridge"
2. I add the 3 references : protobuf3.dll, Grpc.Core.dll and My.dll
3. I compile => no error but the box shows up

Nothing in log nor traces.

If I restart NT8 as it, it cant recover and request to reinstall ninja.

My dll uses two 3d-party :
Grpc.Core 1.4.1 : https://www.nuget.org/packages/Grpc.Core/1.4.1
protobuf3 3.1.0 : https://www.nuget.org/packages/Google.Protobuf/3.1.0

I am confused because my 2 test projects are working fine ! One of them just mock ninjatrader objects ... One is c# console, the other is a c# gui app, all 4.5.0.

I can provide you the c# source file of the strategy call these, my dll and the dependencies.

Thanks for your help

Hello carmiFR,
Thanks for your post.

It sounds like you are going through the correct process. Is your custom dll located inside your \Documents\NinjaTrader 8\bin\Custom\ folder when you export it?

I compile => no error but the box shows up

Just to clarify- do you mean the 'export successful' box? If not, which box do you mean?

If you can provide me with the resources you mentioned that would also help alot. If you like, you may write into PlatformSupport(at)NinjaTrader(dot)com and reference this forum post. I will be able to take a closer look on my end.

I mean it looks like the compilation goes OK but then when NT tries to reload the custom assembly it generates the messagebox like the image attached.

I send you the material to reproduce.

Thanks !

It seems that upgrading to latest version (8.0.13.1) fixed the dynamic load (strange) exception.
