DapperPlusContext options.Log does not work without .Entity().

[VictorioBerra]

Description

This does not work:

var context = new DapperPlusContext(connection);
context.UseBulkOptions(options => options.Log = s => Console.WriteLine("Bulk progress..."));

It only works if used like this:

context
	.Entity<Invoice>()
	.UseBulkOptions(options => options.Log = s => Console.WriteLine("Bulk progress...")) // This works!
	.Identity(x => x.InvoiceID, true);

Hello @VictorioBerra ,

This one is really not obvious,

The UseBulkOptions work like a deferred method such as .Where in LINQ. It will only apply to bulk operations that will follow it and not to any bulk operations that will be executed in the context.

For example, here is a working example:

context.UseBulkOptions(options => options.Log = s => Console.WriteLine("Bulk progress...")).BulkInsert(invoices);

We did it this way as a different bulk operation could require different bulk options.

Let me know if that explains correctly the cause and solution of this issue.

Best Regards,

Jon

@JonathanMagnan One last question on this, does other methods follow that same logic?

IE .Identity and .Key and .MapValue works work like a deferred method such as .Where, or is this only for .UseBulkOptions?

Hello @VictorioBerra ,

Only UseBulkOptions

Other methods used for mappings such as Identity and Key already set the configuration. So you can either chain or not as you wish.
