Sachin Singh · Answer

under include you can't specify property name rather you will have to specify DbSet Name, instead of userName user TableName(DbSet Name) var PaidUser = _context.UserMaster .Include(u => u.UserChild).Where(x => x.UserId == x.UserId).ToList();

if you have navigation property in your table, include will work , otherwise you have no option other than join. var soDTO = from so in db.SalesOrderHeaders .Include(s => s.SalesOrderItems) select so; or var SDto=db.SalesOrderHeaders.include(x=>x.SalesOrderItems).ToList();

Hi Sourabh. There is a simple way to get data from two tables using .Include() var customer = context.Customers.Include(c => c.Invoices); I will join the tables with foraign key relation.

Here you are doing wrong by adding propery into Inculde. Your UserMaster object alredy have the UserName so no need to include. Include is just used to get the data from other table which are in foraign key relation. In short, what you expect the output from this statement?

//var PaidUser = _context.UserMaster // .Include(u => u.UserName).Where(x => x.UserId == x.UserId).ToList();
