I wrote an article about LINQ to SAP at, a new LINQ provider I developed for the company Theobald Software GmbH in Stuttgart, Germany. This provider allows you to easily connect to SAP/R3 systems using the LINQ technology and a Visual Studio 2008 Designer. LINQ to SAP is part of the ERPConnect software suite that interconnects SAP/R3 systems with .NET. You can find more details here.

Querying and transferring data from SAP to .NET using the ERPConnect library

A fellow of mine wrote an interesting article about a very nice and useful library called ERPConnect from Theobald Software. It allows .NET developer to easily access SAP systems to query data, execute BAPIs and much more. Have a look!
