LINQ JOIN with WHERE condition - asp.net-mvc

Question

I have a problem with the creation of LINQ query with lambda expression. I need join two tables and make some conditions. I have two tables MSR and BOMDetail.
MSR had theese columns -> MSRID, PN, Buyer,Plant EditDate.
BomDetail had theese columns -> BOMID, PN, AltQty, Plant, EditDate.
And i need to write this query into LINQ.
SELECT MSR.PN, Buyer, MSR.EditDate, MSR.Plant FROM MSR
JOIN BomDetail bd ON MSR.PN = bd.PN AND MSR.Plant = bd.Plant
WHERE LEN(ISNULL(bd.AltQty,''))>0
I need to make 2 conditions PN must equals between tables and Plant's too.
I have for result ViewModel in asp.net MVC.
public class MSRViewModel
{
public string PN { get; set; }
public string Buyer { get; set; }
public string Plant { get; set; }
public DateTime EditDate { get; set; }
}
And here is my sample, it works fine, but i don't know where i must write the second condition for bd.Plant = MSR.Plant.
var data = DbContext.BomDetails.Where(x => !string.IsNullOrEmpty(x.AltQty))
.Join(DbContext.MSRs
, bd => bd.PN,
msr => msr.PN,
(bd, msr) => new MSRViewModel
{
PN = msr.PN,
Buyer = msr.Buyer,
Plant = msr.Plant,
EditDate = msr.EditDate
}).ToList().AsEnumerable();
Thanks.

You can do this as follows:
var data = DbContext.BomDetails.Where(x => !string.IsNullOrEmpty(x.AltQty))
.Join(DbContext.MSRs
, bd => new { bd.PN, bd.Plant },
msr => new { msr.PN, msr.Plant },
(bd, msr) => new MSRViewModel
{
PN = msr.PN,
Buyer = msr.Buyer,
Plant = msr.Plant,
EditDate = msr.EditDate
}).ToList().AsEnumerable();
