Turn off EF change tracking for any instance of the context [duplicate]

问题

This question already has answers here:

Global setting for AsNoTracking()? (5 answers)

Closed 6 years ago.

I have a context to a read-only database for reporting and I am writing lots of code, like this:

using (var context = new ReportingContext())
{
    var reportXQuery = context.ReportX.AsNoTracking();

    // Do stuff here with query...
}

Is there a way to set the AsNoTracking bit so that just newing up the ReportingContext above would automatically use AsNoTracking instead of needing to remember to explicitly call it every query?

回答1:

Try changing your context constructor to this:

public ReportingContext()
{
this.Configuration.AutoDetectChangesEnabled = false;
}

EDIT:

This will after all not help you, as stated on Arthur's blog, it is usable only in particular scenarios:
