Providers should implement this method to provide a non-default implementation for Overload overloads. The default implementation invokes the synchronous System.Data.Common.DbCommand.ExecuteReader method and returns a completed task, blocking the calling thread. The default implementation will return a cancelled task if passed an already cancelled cancellation token. Exceptions thrown by ExecuteReader will be communicated via the returned Task Exception property. This method accepts a cancellation token that can be used to request the operation to be cancelled early. Implementations may ignore this request.Providers should implement this method to provide a non-default implementation for System.Data.Common.DbCommand.ExecuteReader overloads.The default implementation invokes the synchronous System.Data.Common.DbCommand.ExecuteReader method and returns a completed task, blocking the calling thread.
