[System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Design", "CA1031:DoNotCatchGeneralExceptionTypes", Justification="Exception provided in the returned task.")]
public virtual System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeography> GetGeographyAsync (int ordinal, System.Threading.CancellationToken cancellationToken);

abstract member GetGeographyAsync : int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeography>
override this.GetGeographyAsync : int * System.Threading.CancellationToken -> System.Threading.Tasks.Task<System.Data.Entity.Spatial.DbGeography>

Parameters

ordinal: Int32

The ordinal of the column that contains the geography value.

cancellationToken: CancellationToken

Remarks

Providers should override with an appropriate implementation. The default implementation invokes the synchronous GetGeography(Int32) method and returns a completed task, blocking the calling thread.
