How to execute with a copied dll from another machine - c#

I am trying to provide a colleague with a dll that is from my build so she can execute with the changes i have made. Unfortunately she gets the following error

The system was unable to launch the requested screen. ---> Unable to display screen. ---> System.IO.FileLoadException: Could not load file or assembly 'file:///name.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) ---> 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

Now if she were trying to run it in visual studio i could set the loadFromRemoteSources switch - however this dll is replacing a dll in an install version on a vagrant box. How can i enable the dll to run in this scenario?

Thanks
