.dll file cant load due to previous .NET

I have a .dll file compiled and written in VB express 2010 back in 2011 by my peer. Fast forward to 2015, Im trying to netload this .dll file with no success. is there anyway to migrate the codes and hopefully a tutorial for it.

Cheers

This is my error code.

Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly

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. See

Hi!

I just had this error myself and found a solution through Kean Walmsleys post:

Locate your acad.exe.config file, usually in C:\Program Files\Autodesk\AutoCAD 2015\acad.exe.config.

Add:

My file looks like this:

Hope this will help you!

Firstly, and to both of you, welcome to CADTutor.

Second, please be mindful to use [code ] Tags.

To the issue, not knowing what is provided in the made-for-2011 assembly you're attempting to load, if enabling LoadFromRemoteSources is unsuccessful, it will likely be due to the fact that the API has been broken since 2011. Put simply, the advent of Core Console (AcCoreMgd.dll) now requires code be recompiled for newer versions, first in 2013, and then again in 2015 following API changes.

If the latter is in fact the issue, then you're limited in what steps can be taken, without access to the source-code... Something which we can get into if needed, so long as the original author did not obfuscate the code at compile (unlikely for internal code, YMMV).

Cheers
