Document configuration of triggers for SaveChanges

[ehsan12021]

Hi,
I installed EF core version Preview 7 when I insert new record to a table that has a trigger I,ve got below error:

EF core preview 7 - latest preview release.

Error message:

Could not save changes because the target table has database triggers. Please configure your entity type accordingly, see https://aka.ms/efcore-docs-sqlserver-save-changes-and-triggers for more information.

thank you.

@ehsan12021 This is expected behavior. Do you have some specific question about it?

Thank you for your response.
How can I prevent an error ??
Temporarily I had to go back to stable version.6.0.5

@roji Is this documented yet?

[roji]

@ajcvickers no, I'll definitely prioritize this given that people are starting to run into it.

In the meantime, to resolve this, inform EF Core that the table in question has a trigger by calling HasTrigger():

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Blog>()
        .ToTable(tb => tb.HasTrigger("TriggerName"));
}

(the actual name doesn't matter at this point, since EF doesn't actually try to create the trigger - but that may change in the future)
