Remarks
This overload expects the requestUri to end with a ServiceOperation or ServiceAction that returns void.
Applies to
Execute<T>(DataServiceQueryContinuation<T>)
Sends a request to the data service to retrieve the next page of data in a paged query result.

- T
The type returned by the query.
Parameters
- continuation
- DataServiceQueryContinuation<T>

Returns
The response that contains the next page of data in the query result.
Applies to
Execute<TElement>(Uri)
Sends a request to the data service to execute a specific URI.
public virtual System.Collections.Generic.IEnumerable<TElement> Execute<TElement> (Uri requestUri);abstract member Execute : Uri -> seq<'Element>
override this.Execute : Uri -> seq<'Element>Public Overridable Function Execute(Of TElement) (requestUri As Uri) As IEnumerable(Of TElement)Type Parameters
- TElement
The type that the query returns.
Parameters
- requestUri

Returns
The results of the query operation.
Exceptions
When a response is not received from a request to the requestUri.
When requestUri is null.
When requestUri is not a valid URI for the data service.
When an error is raised either during execution of the request or when it converts the contents of the response message into objects.
When the data service returns an HTTP 404: Resource Not Found error.
