I found myself in the same position. The solution I found appears to be the nuclear option to globally enable the option. This solution was found on SO here: https://stackoverflow.com/a/
Reposting it, as seen on SO.
Adding the loadFromRemoteSources switch to machine.config solved the problem.
MSDN
The
loadFromRemoteSourceselement specifies whether assemblies from remote sources should be granted full trust.
Example
<configuration>
<runtime>
<loadFromRemoteSources enabled="true"/>
</runtime>
</configuration>
You can find machine.config here:
32-bit
%windir%\Microsoft.NET\Framework\[version]\config\machine.config
64-bit
%windir%\Microsoft.NET\Framework64\[version]\config\machine.config
