Just like the Java SDK, eBay offers a kit for the .NET community codebase project. The documentation of the kit contains .Net release notes, installation requirements, guides, libraries, and references. Every 2 weeks developers will see enhancements in API releases in the trading API release notes section. eBay provides additional support through forums for complimentary accounts and live help for paid accounts.
