WCF Data Service Client Utility (DataSvcUtil.exe)

DataSvcUtil.exe is a command-line tool provided by WCF Data Services that consumes an Open Data Protocol (OData) feed and generates the client data service classes that are needed to access a data service from a .NET Framework client application. This utility can generate data classes by using the following metadata sources:

For more information, see How to: Manually Generate Client Data Service Classes (WCF Data Services).

The DataSvcUtil.exe tool is installed in the .NET Framework directory. In many cases, this is located in C:\Windows\Microsoft.NET\Framework\v4.0,. For 64-bit systems, this is located in C:\Windows\Microsoft.NET\Framework64\v4.0. You can also access the DataSvcUtil.exe tool from the Visual Studio command prompt (Click Start, point to All Programs, point to Microsoft Visual Studio 2010, point to Visual Studio Tools, and then click Visual Studio 2010 Command Prompt).
