Grasshopper Runtime question: *.config locations

Hi,

I am trying to use an external SDK (from Amazon Web Services) in my plugin. This assembly requires authentication through a App.config file that must be present in the application that is currently executing. This all works fine for console applications or Unit-testing as long as the App.config file is present, in the respective executing application or assembly.

However in grasshopper I am having some trouble to pin-point where exactly I should store my config file locally so that it is picked up by rhino/ grasshopper/ my plugin.

To clarify the AWS support shows in some examples how to test the presence of the config file using the:

NameValueCollection appConfig = ConfigurationManager.AppSettings;

By checking the keys/ values of the returned collection you can check if the credentials are set. I call this same method in Grasshopper and it returns nothing. When calling a method from the Amazon SDK I get the following:

1. Solution exception:Could not load file or assembly 'AWSSDK, Version=2.0.8.0, Culture=neutral, PublicKeyToken=9f476d3089b52be3' or one of its dependencies. The system cannot find the file specified.

I think file that cannot be found is my config file. However where should I put it? Using some reflection I have found:

• BaseDirectory: C:\Program Files\Rhinoceros 5.0 (64-bit)\System\
• ExecutingAssembly: C:/Program Files/Common Files/McNeel/Rhinoceros/5.0/Plug-ins/Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)/0.9.70.0/Grasshopper.dll

Can someone explain me how I should interpret the default runtime configuration of Grasshopper? Should I store my config in the Rhino system directory or in the grasshopper directory? (neither worked for me) 

What about my own .gha plugin?

Thanks,

Dion
