Linq to Entity Join table with multiple OR conditions

I need to write a Linq-Entity state that can get the below SQL query

SELECT  RR.OrderId
FROM    dbo.TableOne RR
        JOIN dbo.TableTwo  M ON RR.OrderedProductId = M.ProductID OR RR.SoldProductId= M.ProductID
WHERE   RR.StatusID IN ( 1, 4, 5, 6, 7 )

I am stuck with the below syntax

 int[] statusIds = new int[] { 1, 4, 5, 6, 7 };
            using (Entities context = new Entities())
            {
                var query = (from RR in context.TableOne
                             join M in context.TableTwo on new { RR.OrderedProductId, RR.SoldProductId} equals new { M.ProductID }
                             where RR.CustomerID == CustomerID 
                             && statusIds.Any(x => x.Equals(RR.StatusID.Value))
                             select RR.OrderId).ToArray();
            }

this gives me below error

Error 50 The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'Join'.

How can I do a Multiple condition join for a table.


You don't have to use the join syntax. Adding the predicates in a where clause has the same effect and you can add more conditions:

var query = (from RR in context.TableOne
             from M in context.TableTwo 
             where RR.OrderedProductId == M.ProductID
                   || RR.SoldProductId == M.ProductID // Your join
             where RR.CustomerID == CustomerID 
                   && statusIds.Any(x => x.Equals(RR.StatusID.Value))
             select RR.OrderId).ToArray();

Change your query syntax from using join to using an additional from clause

  var query = (from RR in context.TableOne
               from M in context.TableTwo.Where(x => x.ProductID == RR.OrderedProductId || x.ProductID == RR.SoldProductId)
               where statusIds.Any(x => x.Equals(RR.StatusID.Value))
               select RR.OrderId).ToArray();

Multiple Joins :

var query = (from RR in context.TableOne
             join M in context.TableTwo on new { oId = RR.OrderedProductId,  sId = RR.SoldProductId} equals new { oId = M.ProductID, sId = M.ProductID }
             where RR.CustomerID == CustomerID 
             && statusIds.Any(x => x.Equals(RR.StatusID.Value))
             select RR.OrderId).ToArray();
