Autocad Library does not work with Autocad 2019

When trying netload on the dll I get the following error:

Cannot load assembly.
Error details: System.IO.FileLoadException: Could not load file or assembly 'MomenTumV2CadLayouting.dll' or one of its dependencies.
Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'MomenTumV2CadLayouting.dll' ---> System.NotSupportedException: 
An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework.
This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous.
If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch.

Looking it up, apparently downloading files from the internet - i.e. the dll - makes them blocked in Windows 10 and Autocad 2019 blocks execution. You should add a step to the tutorial that tells people to open the properties on the file and unblock.
