Hi,

I have written a function in the <MyApplication>RepositoryBase class that takes List of entity (List<Product> NewProducts) as input parameter. And following is the code of the function. Essentially, I am trying to bulkinsert products in the database. But in the last line of the code (i.e. Context.BulkSaveChanges();), it throws the following error: Exception: KeyNotFoundException Message: The given key was not present in the dictionary.

            Context.ChangeTracker.AutoDetectChangesEnabled = false;
            Context.Set&lt;Product&gt;().AddRange(NewProducts);
            Context.ChangeTracker.DetectChanges();
            Context.BulkSaveChanges();

Any idea what could be the reason and how to resolve this?

Regards, Mahendra

    Thanks for letting us know!

    In case anyone has the same issue, upgrade Z.EntityFramework.Extensions.EFCore to v2.0.8. Resolved here: https://github.com/zzzprojects/EntityFramework-Extensions/issues/63

    Hi I would also like to implement Z.EntityFramework.Extensions.EFCore

    Can you explain how to use it. I have installed the nuget in the Application section

    How do I user it?

    I would like to update a bool to true on the following:

    var timesheets = _timesheetsDetailRepository.GetAll() .Where(e => e.TimesheetId == input.Id);

    var context = _timesheetsDetailRepository.GetDbContext();
context.BulkUpdate(timesheets);
