New dll in Dyalog APL

Is it possible to use a new dll in Dyalog APL? I can use the existing dll's just by setting ⎕USING, but this does not work if I download a new dll. Simply copying the dll in the directory and calling ⎕USING←'new_dll,new_dll.dll gives me the error:

Assembly load failed:
Could not load file or assembly 'C:\Program Files\Dyalog\Dyalog APL-64 19.0 Unicode\new_dll.dll' or one of its dependencies. The system cannot find the file specified.
Could not load file or assembly 'file:///C:\Windows\Microsoft.NET\Framework64\v4.0.30319\new_dll.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

So I guess I must be missing some step. Has anyone done it?

More precisely, I want to use EPPLUS and IronXL in Dyalog APL.

I will use as an example the NuPkg Newtonsoft.Json as it is available under the MIT License.

  1. I downloaded the package from nuget.org/packages/Newtonsoft.Json

  2. Important step: In Windows Explorer, I right clicked on the .nupkg file and chose Properties. I ticked the Unblock button.

  3. I used an unzip program to extract all the files inside the .nupkg package file.

  4. In Dyalog, I verify that I can do some very basic operations with the Newtonsoft.Json namespace:

      ⎕using←'Newtonsoft.Json,D:\cust\tp5dec24\lib\net45\newtonsoft.json.dll'
      JsonConvert
(Newtonsoft.Json.JsonConvert)
      JsonConvert.DefaultSettings
[Null]
      serializer←⎕NEW JsonSerializer
      serializer
Newtonsoft.Json.JsonSerializer
