I have two entities, each with separate edmx files since they came from various databases. However, there is an implied connection between them....Foo...
s, for instance....What is the quickest and least resource-intensive approach to do this join using EntityFramework?...Thanks.
I've seen several articles on using a database in a WPF.Net 4 application. I believe the primary two technologies are:...SQL with Linq (L2S)...Enterprise Framework (EF)...I sometimes see mention of the Linq to Entities (L2E) technology, but I can never figure out what makes L2E different from EF....So, my question is: Are there any differences betw...
I have studied every topic on how to use the Entity Framework with Linq to Entities (.NET 3.5) to create the LEFT OUTER JOIN equivalent, but I haven't been able to find a solution to the following issue....Considering the two tables shown below as objects:... public class Foo

I'm attempting to convert a multi table join to utilize the Entity Framework since I'm new to it. The first SQL had a similar appearance....JOIN tab_NewsCommunities S1 ON S1.News_ID = tab_News.NewsID
inner join tab_communities com on S1.Community_ID = com.Community_ID and com.RecordStatus_ID = 2
JOIN tab_Communities c ON S1.Community_ID = c.Communi...
Can somebody assist me in resolving my problem? I'm use the code below:...public IEnumerable<InvoiceHeader> Getdata(Expression<Func<InvoiceHeader, bool>> predicate)

Please view the picture....In order to merge 5 distinct tables on 1 to 3 different columns, I'm attempting to build a LINQ query. I just duplicate the join portions from the examples for the first two tables for tables three through five....UPDATE: How do I make the LINQ query below work?... var match = (from t1 in context.cKNA1
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
It says that only parameterless constructors and initializers are supported in LINQ to Entities when I attempt to combine two tables and build a tuples list....var list = (
from a in db.CategoryRatings
join c in db.OverallPerformanceByCategories
on a.CategoryRatingId equals c.CategoryRatingId
where c.ReviewId == review.ReviewId
