    How to instance new Objects from .DLL

    Hi, admins!

    After creating in C# my own Class library with Framework 4.5, compiling it with VisualStudio, linking the .DLL file from an NT8 strategy using "References", and defining the namespace in the strategy, I am not able to instantiate an object from the new type of my library.

    Whenever I try, I get the following error: "System.NullReferenceException: Object reference not set to an instance of an object." and then NT8 closes without being able to reopen it. The only solution to reopen NT8 is to replace a fresh copy of the file NinjaTrader.Custom.dll

    When I do the same operation from an AddOn, I get it perfectly. I'm frustrated and I do not understand the difference. What can I miss?

    Thank you very much in advance.

    SOLVED!!

    It was important to put the .DLL file in C:\Users\xxxxxx\Documents\NinjaTrader 8\bin\Custom\ directory , reference it from Strartegy after that, and finally to restart NT8.

    Regards!
