.dll error but no compile error

[sidlercom80]

i am trying to integrate a .dll file into the system, everything works smoothly. i can also compile at the end, but unfortunately the following error message is displayed when nt8 restarts, as shown in the picture. even after restarting, i can compile without an error message, but this message appears in the log. can anyone help me? of course i used the search function, unfortunately without success ;-)

Hello sidlercom80,

Thank you for your post.

Where within the NinjaTrader folder have you placed the .DLL file? Is it in the bin > Custom folder? Custom DLL files should be placed in the Custom folder - if it is not currently there, please move it there and adjust your references in Visual Studio and NinjaTrader accordingly.

Within NinjaTrader, is there a reference to the DLL listed in the References window? Right click on the NinjaScript Editor and select References to check this.

Thanks in advance; I look forward to assisting you further.

Hi _Kate, I have made a picture with this information, see above ;-)

but here again with pleasure
folder: C:\Users\xxxxxxx\OneDrive\Dokumente\NinjaTrader 8\bin\Custom\packages\Dao.ConcurrentDictionaryLazy .1.2.0
reference to .dll: C:\Users\xxxxxxx\OneDrive\Dokumente\NinjaTrader 8\bin\Custom\packages\Dao.ConcurrentDictionaryLazy .1.2.0\lib\net45\Dao.ConcurrentDictionary.dll

Hello sidlercom80,

Thank you for your reply.

Generally the DLL would need to be in the Custom folder and not in a further subfolder. If you move the DLL itself out of the subfolders and into the Custom folder itself, and change your references to reference it in that location, do you see the same?

Thanks in advance; I look forward to assisting you further.

Hi _Kate, how stupid of me I was not aware that it should not be a subdirectory. everything seems to be working now, thank you very much for your help.
