Visual Studio :: Missing ADO.NET Entity Data Model Template In MVC 2 Applications?
Jun 10, 2010I've been using VS2010 to look at the new ASP.NET and specifically MVC 2. I have gone through the 0.8 release of the MvcMusicStore sample on CodeProject (good job so far).
Now, I'm working on a project to explore MVC more deeply and after creating a table in a local SQL table, I went to create an ADO.NET entity data model to work with the table data. When I get to the list of templates, the total list of templates are:
SQL Server Database Text File XML File XML Schema That's everything (meaning when C# is selected at the top of the dialog's installed templates).
I've re-installed VS2010 (gone through the control panel and the maintenance option for VS2010). There's no Linq, Data Set, Database Unit Test, nothing....
It was there before, it's not now.
UPDATE : I did find this article: [URL] I did run devenv /installvstemplates. It ran without errors, however, the error still persists.
The article said if the "solution" was not a real solution, to re-install VS2010 (Really???). So I went to do so. The ADO.NET entity object framework is installed.
Why would VS2010 "forget" something so intrinsic?
ADO.NET :: Unable To Connect To DB2 Database From Visual Studio 2010 Express - Entity Data Model
Nov 16, 2010In Visual Web Developer-2010, I have been trying to connect to IBM DB2 Database after installing the DB2 9.7 client (both supports VS2010/.Net4) so that I can use "ADO.NET Entity Data Model", but while clicking "New Connection" I can only see the list of Data Sources and Data Provider only related to MS SQL server. This is totally blocking my work, I am not able to work further since I cannot even establish the connection to my db2 database using this new editor so that I can create the edmx files in the solution for non MSSQL databases. Kindly provide me the solution ASAP, since my further work is blocking due to this.

View 1 RepliesMVC :: Using Data From Multiple Entity Framework4 Model Entity Objects In MVC2 Controller?
Sep 29, 2010getting data from multiple Entities models into an MVC controller. Most of the examples I have seen for using EF in an MVC2 app only use a single entitiy.
I have just started using MVC2 in C# using the Entity Framework models (CIOps.model) created from an SQL database. I can create the controller and views using single tables of the model in MVC2, but I just cannot get my head around how to get data from multiple entity tables into the controller (similar to joins in T-SQL). I have included an example below of the controller code that works with a single entity table, tbl_tours (tbl_tour in DB).
Could someone please illustrate how this code would be changed to include additional columns from FK tables in addition to tbl_tours columns. E.g. the clients name from the tbl_clients, the coordinators name from the tbl_employees, and costs from tbl_costs entities? Is it possible to do this directly using the EF model entities/classes that are already created and not use LINQ, POCO, Repositories, etc.? The FK relationships are already in the EF models. I have included the whole controller code, but I just need a few examples of how to join the multiple entities, not rewrite every CRUD function function in the controller. I think this will get me over the hump in using EF in an MVC2 App. Also ignore the fact I am using the home controller, this will change in the application.

ADO.NET :: Entity Data Model - How To Use
Feb 16, 2011I program in ASP.NET for a while now. My applications uses always the DataSet. Some told me that Entity Data Model is the DataSet for LINQ. Now I want to try to working with it I have some questions but can't find the answers. I hope someone can. When I build an application I use the 3-tier structure. So Presentation-layer, Business-layer and the Data-layer. Normally I had some classes in the Data layer with specific methods to interact with the DataSet. When I read the table or something I create an object for the business layer.
With the Entity Data Model it seems a little bit confusing. If I read a table (for example Company) the edmx has created an class already. So is the edmx a replacement for the Data-layer and also for the Business layer? Is the edmx also a good use for multi-user application or is a connected application better?

Exporting Entity Framework 4 Data Model To Entity Framework 3.5?

Our project is the 1st to go to .Net 4.0 using Entity Framework and we (the team) were wondering if there was a way for the other projects that "might" need to access our data that are still using the .Net 3.5 framework.
Visual Studio :: Configure SQL Server In VS2010 / Creating Model Classes With Linq To SQL?
Mar 17, 2011I can't believe I'm having so much trouble finding this information. I'm endeavouring to learn about creating model classes with Linq to SQL. By default VS2010 wants to use SQL Express, but our organisation has several database servers for development so I'd rather use one of those. PLEASE can somebody tell me how I can configure VS2010 to do that, as all I get is 'A network-related or instance-specific error occurred while establishing a connection to SQL Server ... Verify that the instance name is correct'. Yeah, thanks Microsoft. Actually telling me how to verify the instance name would be a really good move here.
