ExecuteReader requires command to have transaction when connection assigned to command is in pending local trans

Example code

using (SchoolDataContext db = new SchoolDataContext())
{
    using(using var Transaction = db.Database.BeginTransaction())
    {
        SudentDtls SudentDtls = (from p in db.SudentDtls where p.SudentId == SudentId && p.StatusId == (int)EStatus.ActiveStatus select p).FirstOrDefault();
        SudentDtlsHistory SudentHistory = (from p in db.SudentDtlsHistory where p.SudentId == SudentId && p.StatusId == (int)EStatus.ActiveStatus select p).FirstOrDefault();
 
        SudentDtls = Automaper<SudentDtlsHistory, SudentDtls>(SudentHistory, SudentDtls);
        SudentDtls.ModifiedBy = UserId; 
        SudentDtls.ModifiedDate = DateTime.Now; 
        db.SaveChanges(); 

        MStudentData data = SqlQueryExtensions.SqlQuery<MStudentData>(db, "GetStudentData");
        if (data != null)
        {
                        
        }
        Transaction.Commit();
    }
}

SqlQueryExtensions: Class at SchoolFrameWork SqlQueryExtension method, asking for the current transaction but how to supply transaction to SqlQuery.

@viktorz You typically need to tell EF to use the transaction. For example:

dbContext.Database.UseTransaction(transaction);

See the Transactions documentation for more info.

However, I see you are also using an EF execution strategy. This complicates use of transactions. See Execution strategies and transactions for more info.
