Called just before EF intends to call ExecuteNonQueryAsync().

Parameters

command
DbCommand

The command.

eventData
CommandEventData

Contextual information about the command and execution.

result
InterceptionResult<Int32>

Represents the current result if one exists. This value will have HasResult set to true if some previous interceptor suppressed execution by calling SuppressWithResult(TResult). This value is typically used as the return value for the implementation of this method.

cancellationToken
CancellationToken

A CancellationToken to observe while waiting for the task to complete.

Returns

Task<InterceptionResult<Int32>>
ValueTask<InterceptionResult<Int32>>

If HasResult is false, the EF will continue as normal. If HasResult is true, then EF will suppress the operation it was about to perform and use Result instead. An implementation of this method for any interceptor that is not attempting to change the result is to return the result value passed in, often using FromResult<TResult>(TResult)

Exceptions

OperationCanceledException

If the CancellationToken is canceled.
