SAP provides a number of back-end connectivity solutions that enable .NET developers to access SAP back-end systems and services. For more information, check out the following sections:
SAP ES Explorer for .NET
SAP Enterprise Services Explorer tool for Microsoft .NET (SAP ES Explorer for .NET) is an add-in for Microsoft Visual Studio 2005 and 2008 that helps to leverage SAP SOA by enabling .NET developers to discover SAP enterprise services and consume them in their applications, as well as publish their own custom services in the SAP Services Registry. It is a design-time tool that succeeds the SAP connector for Microsoft .NET (NCo) as the connectivity tool between SAP back-end systems and the Microsoft. NET platform.
Susanne Rothaug announces the availability of the tool in her blog The SAP Enterprise Services Explorer for Microsoft .NET: New interoperability offering for the Services Registry.
Anne Tarnoruder provides an overview of the tool's features and capabilities in her article Introducing SAP Enterprise Services Explorer for Microsoft .NET.
Download and install.

The documentation of ES Explorer is automatically available in the Microsoft Visual Studio local help after installation. You can optionally download and locally install the standalone HTML version.
Provides detailed instructions for installing and configuring ES Explorer for .NET.
SAP Connector for .NET
The SAP connector for Microsoft .NET is an add-in for Microsoft Visual Studio 2003 that enables design-time and runtime connectivity between the Microsoft .NET platform and SAP back-end systems based on SAP Remote Function Calls (RFC)
SAP .NET Connector 2.0 (Link to the Service Market Place, registration is required)
Learn a workaround that enables easy design-time connectivity to SAP back-end systems in Visual Studio 2005 by creating the connector proxies in Visual Studio 2003 and porting them to Visual Studio 2005.
Learn how to build .NET clients for SAP applications using web services and various security options.
To demonstrate interoperability features of SAP Enterprise SOA in its integration with Microsoft Office tools, Anne Tarnoruder of SAP NetWeaver Product Management, and Dudu Benabou of Microsoft Consulting Services introduce a sample InfoPath 2007 form template that consumes SAP enterprise services to retrieve information from back-end systems. For better understanding of each implementation step in the article, you can download and examine the accompanying code.
Another excellent walkthrough from Boris Mueller shows the process of consuming enterprise services using Microsoft .NET 3.0 and Visual Studio 2005. From finding enterprise services on the ES Workplace (SDN login required) to the source code generated by a Visual Studio 2005 project, this thorough guide shows just how flexible enterprise services can be.
