I downloaded the zip file and extracted into a folder on my c drive. The folder I chose was OpenNETCF.
I then open Visual Studio 2005
I choose File | Open | Project or Solution
I select the folder OpenNETCF and choose the file OpenNETCF.NET.FTP
I then get an error message that says that the program location is not trusted. I click OK (which is saying to it ignore)
It then comes up with an error "Error retrieving information from user datastore. Platform not found"
Hope this is enough detail - I am sure that I am doing something incorrect..
