A complete C# sample app that connects to the ETrade API via Oauth
Uses: https://github.com/jejernig/DevDefined.OAuth---Etrade
This is a simple C# console app with the BaseOauthRepository class written by jejernig. I added a class that exposes a few of the Etrade rest calls to get you started. It was written in VS2010, .NET v4.0.
I know a lot of people have been looking for a simple example for this. jejernig helped me, so I hope this helps others.
The project is in ZIP format in the downloads area. (I'm still learning github)
