问题 there is a odata webservice, i can get metadata from http://service-uri.com/$metadata which contains definition of all its model object, is there any tools that i can use, to convert that metadata xml to data contract class in C#? 回答1: The WCF Data Services Client library can generate C# classes for you from the $metadata endpoint.

问题 I have a bigger SAPUI5 application with multiple pages. If user navigates through all these pages, they will reside in memory of course. Now I have the problem that some of these pages have a complex context with several bindings to an ODataModel. That leads to the problem that a .refresh() call on the underlying ODataModel take some time. Because: all known bindings will be reloaded (also from pages not currently shown) Now I am searching for a better solution to refresh the ODataModel. The
