Notes
- You can update or modify the SimpleClient to try the available eXtreme Scale client for .NET APIs. Locate the SimpleClient in the <installation_directory>\sample\SimpleClient in the installation directory, and load this file into Visual Studio to view the sample application that uses simple create, retrieve, update, and delete operations. Use the SimpleClient as a guide for accessing the data grid. You can modify this application or write new applications that use the eXtreme Scale for .NET client supported API set.
- .NET client security properties coexist with the other .NET client properties in a single client .properties file.
- The .NET client and REST clients do not expose any client-side plug-ins. Server-side plug-ins are supported when they don’t require any client-side plug-in counterparts. For example, an ObjectTransformer is required on both the server and client. When No is specified, the API does not support the plug-in on the server.
- Server-side plug-ins that are applicable to clients are instantiated by the client by default and must be added to the classpath. The REST Gateway does not currently allow an ObjectGrid client override XML file.
