Sends ScalarExecuting(DbCommand, DbCommandInterceptionContext<Object>) and ScalarExecuted(DbCommand, DbCommandInterceptionContext<Object>) to any IDbCommandInterceptor registered on DbInterception before/after making a call to ExecuteScalarAsync(CancellationToken).

public virtual System.Threading.Tasks.Task<object> ScalarAsync (System.Data.Common.DbCommand command, System.Data.Entity.Infrastructure.Interception.DbCommandInterceptionContext interceptionContext, System.Threading.CancellationToken cancellationToken);

abstract member ScalarAsync : System.Data.Common.DbCommand * System.Data.Entity.Infrastructure.Interception.DbCommandInterceptionContext * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>
override this.ScalarAsync : System.Data.Common.DbCommand * System.Data.Entity.Infrastructure.Interception.DbCommandInterceptionContext * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>

Parameters

command: DbCommand

The command on which the operation will be executed.

interceptionContext: DbCommandInterceptionContext

Optional information about the context of the call being made.

cancellationToken: CancellationToken

The cancellation token for the asynchronous operation.

Returns

Task<Object>

The result of the operation, which may have been modified by interceptors.

Remarks

Note that the result of executing the command is returned by this method. The result is not available in the interception context passed into this method since the interception context is cloned before being passed to interceptors.
