The Exchange Web Services (EWS) autogenerated proxy object models that are created by .NET Framework proxy generators are deemphasized and we do not recommend that you use them for new .NET Framework client development. We recommend that you use the EWS Managed API to develop clients that target the .NET Framework. We recommend that you use the EWS Java API to develop clients that target the Java platform. For more information about the EWS Managed API, see Explore the EWS Managed API.
