View 4 RepliesADO.NET :: LINQ To SQL Vs Entity Framework
Aug 5, 2010Im working on a greenfield project and have to make a decision on the technology we'll use for the data access layer. Ive used LINQ to SQL for a few years and am happy and comfortable with this, but now with entity framework available this is another method to consider. Are there any pitfalls using entity framework as opposed to LINQ to SQL ? Ive read that there are performance issues with entity framework, is this true? Id really like to get an overall feel for using one method over the other, anyone have any thoughts/comments/recomendations?

May 17, 2010i have 2 table missions and missiondays with a relationship 1..n
I want select all missions that has all missiondays with an attribute called "visible" = true
I've tried with:
db.TDP_Missioni.Include("TDP_MissioniDestinazioni").where(p => p.TDP_MissioniDestinazioni.visible == true)
But there is an error. Indeed from p.TDP_MissioniDestinazioni i don't see the table's attributes. I think it's because the relationship is 1..n.

ADO.NET :: Entity Framework - How To Join Tables Without LINQ And With Only String
Sep 30, 2010I have a question about Entity Framework. answer if you know answer on this. I have such query :
[Code]....
Particularly I want to join few tables in one query, but I can NOT use LINQ and can NOT use ObjectQuery with objects mapped to DB fields inside my query. Because each entity creates dynamically. So this is what i
can NOT use : [URL]
The question is can I use something like this instead of using objects?

The purpose is to use Join method of ObjectQuery with syntax as in Where method :[URL]
DataSource Controls :: L LINQ TO SQL Be No Longer Supported In .NET Framework ?
May 8, 2010ASP.NET 4.0 comes up with a bulk of noticable improvements , including freshment of LINQ to Entities model. Other than this , I still remember another .net built-in ORM framework "LinqToSQL" which provides a lighter and more direct way to interact with SQL-server based db system. However, it seems no term concerns "Linq to sql" in .net 4.0 pulication announcement. So I think it might be deprecated in the furture due to .Net team's plan. I wonder if .NET team decide to just choose entity framework to fully serve as the .NET official ORM implement and no longer develop 'LinqToSQL' . Is LinqToSQL really an attemptive speck and not worth holding in the furture?

ADO.NET :: VS 2010 - No Entity Framework Or LINQ Support For SQL Server 2000 SQLOLEDB Connection?
Sep 1, 2010I'm working with Visual Studio 2010 and for Data Connections am connecting to a SQL Server 2000 production database. When I try to drag a table to a .dbml file, the Object Relational Designer says, "The selected object(s) use an unsupported data provider." If I try to create an .edmx file via Generate from database, then the alert is, "This server version is not supported. You must have Microsoft SQL Server 2005 or later."
So VS 2010 has no support for the Data Entity Framework or LINQ when connecting to a SQL Server 2000 database? If that is the case, what is the best data access strategy for this scenario?
ADO.NET :: LINQ Entity Framework Query - Construct "nested" Query?
Jan 22, 2011I have a web app for our golf club. When I compute handicap index for each golfer, I have to select the most recent scores and then a subset of those scores depending on how many rounds of golf the golfer has played. All the scores are entered into a single SQL Express table called "Rounds". Verbally, this is what I'm trying to do:
1) select the twenty most recent golf scores (sort on date descending, "take(20)") [if less than 20 records, then select all available];
2) for this set of records, select the 10 lowest scores (or smaller number if golfer has less than 20 rounds);
3) compute the average round differential for the subset of records, etc. to calculate handicap index (this step is working ok...)
My current VB code has this LINQ query (which is flawed -- it selects the lowest handicap differential scores of ALL records for the filtered user):
[Code]....
How do I modify this query to accomplish items 1) & 2) above? It seems this should be simple, but my experience with queries is still limited.

How do I get the two websites to run together in the same website using different versions of the .NET Framework?
