Migrating to .NET 2.0

As we are now in the process of migrating from Microsoft's  .NET 1.1 to  .NET 2.0, we are providing two versions of the eBay SDK for .NET - the Beta Version, where the complete code source, all samples, and utilities have been re-built using Microsoft's Visual Studio 2005 and .NET 2.0, and the Maintenance Version, for users who need to continue using Microsoft's Visual Studio 2003 and .NET 1.1. Our next full release, scheduled for next Fall, will only contain the .NET 2.0 version.
