This particular error is actually informative, and even gives a URL for how to
fix it: http://go.microsoft.com/fwlink/?LinkId=155569. But I'll summarize:
You're running the script from a network share (looks like you're using
Parallels with shared Mac drives?). Also looks like you're running this code
from the Visual Studio repl? To get this to work you need to add the following
to the <runtime> section of c:\Program Files (x86)\Microsoft Visual Studio
10.0\Common7\IDE\devenv.exe.config:
<loadFromRemoteSources enabled="true"/>
Note: You'll have to add this to any .NET app that runs IronPython scripts from
E:\ which load assemblies (eg, ipy.exe, yourhost.exe ...). I currently have the
same setup with Paralles, and this is what I do. To avoid this, store all your
.NET stuff on an drive actually mounted in Windows.
Also, You didn't need to copy your assembly into IronPython's directory. Store
your assemblies in your own directory, add that directory to sys.path,
sys.path.append("C:\\path\\to\\assemblies"), and then
clr.AddReference("LumensWorks.Framework.IO") will load it. Also, loading the
assembly first and then adding it as a reference isn't necessary, just extra
typing your your part.
