Alles läuft lokal.

Lösung gefunden :) 

Die Exception wird unabhängig davon geworfen, ob die Datei lokal liegt oder nicht. Entscheidend ist, dass es ein Netzwerkpfad ist.

App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <runtime>
    <loadFromRemoteSources enabled="true"/>
  </runtime>
</configuration>

So käme keine Exception. 

Getestet mit: 
var path = @"\\SERVERNAME\BuildResult\MasterBuild\ImportServerMasterBuild\ImportServerMasterBuild 6.0.0.81\Release\ImportServerTests.dll";
var loadFile = Assembly.LoadFile(path);
