Only one of the four tables in the query I'm trying to build will be guaranteed to exist. Creating left joins in EF has always worked for me, but never with more than one join. This is the problem:... var details = (from planInfo in context.PlanInfo
join templateRec in context.ProductTemplates
Avoid using these kind of queries if there are no restrictions or requirements since they can be attacked using SQL injection....With Entity Framework and Linq, practically every phrase, including the one you just wrote, is possible....DbContext.Customer.Where(c => c.CustomerId = id).Distinct();

Is it possible to combine everything into a single call?...FirmFeatures are linked by a foreign key connection. FirmParameters from Nullable FirmId. FeatureI...

where c.ReviewId == review.ReviewId
