ADO.NET :: VS 2010 - No Entity Framework Or LINQ Support For SQL Server 2000 SQLOLEDB Connection?
Sep 1, 2010
I'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?

I have just installed VS2010, and imported a copy of project that uses SQL server 2000 as the database
the project actually runs ok: BUT when I try to use the IDE designer tools to modify a SqlDataSource, or add another SqlDataSource, I get a message" this version is not supported. You must have Microsoft SQL server 2005 or later."
If I build the SqlDataSource manually, it works OK???
So, anyone have a idea why the IDE designers don't support SQL server 2000, since extended support for that version is still active?

I have a db connection string 'ApplicationServices' defined in the connectionString section of web.config and 3 Entity Framework connection strings which have the provider connection string attribute with the same connection string as the one in 'ApplicationServices'. Is there a way to reference connectionString in 'ApplicationServices' for the provider connection string attribute of the EF connection string in the web.config, rather than providing the connection string all over again?

Im 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?

How can I retrieve the Entity Framework 4 connection string from a custom config file, not web.config?
Edit: Is it reasonable to delete the default constructor generated code and recreate it in a partial class to use the pulled in connection string?
I would really like to avoid changing all references to the EF context with an overloaded method including the connection string.
@BrokenGlass: This is what we ended up with:

Is it possible to choose a specific database that will be used with the entity framework? At this time, I use the connection string in the Web.Config as database authentication.
I have twelve databases, each of them has the same structure and the same stored procedure.
There is one database for each client. When a client wants to login into the system, he needs to choose his database name from a listbox.
I would like to create a dynamic connection string which will include the database name chosen by the client.

I'm working on an application that is connected to the online MSSQL database and everything is working fine.The model I'm using is entity model.The problem is that I have to change the connection string from the online database to the local one,but I don't know how.Creating new model isn't an option.I tried changing the connection string in web.config,but errors are the only thing I get.
This is what I have in web.config:
<connectionStrings>
<add name="PravosudnaAkademijaEntities" connectionString="metadata=res://*
PrakModel.csdl|res://*/PrakModel.ssdl|res://*/PrakModel.msl;provider=System.Data.SqlClient;provider connection string='Data Source=HRVOJE-PC;Initial Catalog=pak_baza;Integrated Security=True" providerName="System.Data.EntityClient" />

I'm using Entity Framework 4 for a simple app and would like to bake my connection credentials into the following connection string:
<connectionStrings>
<add name="MyEntities"
connectionString="metadata=res://*/MyDataModel.csdl|res://*/MyDataModel.ssdl|res://*/MyDataModel.msl;provider=System.Data.SqlClient;provider connection string="Data Source=localhostDEV;Initial Catalog=MyDB;UserId=myUser;Password=jack&jill;MultipleActiveResultSets=True""
providerName="System.Data.EntityClient" />
</connectionStrings>
However, the password (which I cannot change) contains an ampersand. ASP.NET throws:
Configuration Error: An error occurred while parsing EntityName. Line XX, position YYY.
If I replace the ampersand in the password with &, I get a SqlException: Login failed for user 'myUser'. Usually this trick works, but I'm guessing that something is failing because this is technically a connection string inside a connection string.
What should I do here? Most of my classes include code like:
using (var context = new MyEntities()) {
// do work
}
Update: It turns out that the credentials I am using are a domain account, so what I really need is Integrated Security=True in the connection string rather than a password.
Encoding the ampersand as indicated in the accepted answer should work fine, though I haven't tested it.

i 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.

On my underlying DB I have 3 tables. 1 of those tables comprises of just the primary keys of the other 2 tables. When I built the Model, it recognised this and so didn't actually generate an entity for this table, but instead made a many to many relationship between the other 2 tables.Now when I save changes against the context. (new records) under the hood the table with just primary keys are not populated. How do I get this table populated?

I 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?
[Code]....
The purpose is to use Join method of ObjectQuery with syntax as in Where method :[URL]
