HELP!!! Unable to load .dll

[songmaverick]

I would like to learn C# to code some function in order to simply the my drawing work..

My IDE : Visual Studio

AUTUCAD 2020

I use Class Library (.NET Framework) templates to create a project and build solution.

I add accoremgd,  acdbmgd,  acmgd in Reference.

I get the .dll from /bin/Debug/.dll and type 'netload' in CAD 2020 to load the .dll file.

But I get this result as follows

I repeat these on my colleague's CAD2020, it is OK..

Could anyone tell me what is wrong with my computer?

Thank!!!

Please Clarify.
Is the dll that doesn't load on your machine loading on your associated machine

or

are you rebuilding on your associates machine and loading it there ?

By any chance are you ignoring a Trusted Location warning ??

Thanks for your reply!!

I do not build the solution on my colleague's computer and I use the same .dll to netload in cad

I am sure no  Trusted  warning appears .

I type 'netload' and choose the .dll and it says unable to .....

there is a warning appearing in my colleagues' CAD .

My colleague's warning is below

I am confused that there is no warning in my CAD!!

Option -> System ->Security Options 

change the Security Level from High to Medium

[songmaverick]

Thanks for your reply , which reminds me of changing the Security Level
I could netload .dll

[kdub_nz]

I had a suspicion it was a 'trust' issue becaue I've seen the wording of the message when cancelling the load from the Security dialog.

Glad it's working.

Thank you very much

I set high security level before . So the warning would not come out .

Your reply reminds me of this .. 

Thank you again!!
