How To Specify Metadata Location In Connection String When Using An Edmx File
Jan 29, 2010
I have a web project with a data model defined in an edmx file. The connection string starts like this:
metadata=res://*/;
This has worked fine for a while. But somebody else working on the project created a dll that also uses the entity framework and added it to the bin folder. Now when I try to create my connection there is an error loading the metadata.
Aside from totally changing the way one or both of us is doing things, I wonder if the problem can be fixed if my connection string can be changed to only look for the metadata defined in my edmx file. The problem is, for the life of me I can't find the right syntax to do this. The metadata is embedded in the output assembly, so there are no physical metadata files to point to. How exactly should I specify the metadata location in the connection string?

I have a problem registering a stored procedure in the EDMX file in my web application. When I try to add the function, I have the message:
"No Database connection is defined for this model"
All the buttons are also disabled. If I click on the white spaces to get the properties of edmx file, the connection string is blank. I am not sure how this came about. Everything compiles and runs I can add tables and views but not Stored procedures. I created a test project from the scratch and added a new edmx file and I was able to add the stored procedure. i nthe new project the connection string is defined. Connection strings are defined in the web.cnofig. I suspect that somehow the edmx file or project got corrupted.

I've got 3 connection strings in my app:
<add name="DBConnectionString" connectionString=""/>
<add name="ADConnectionString" connectionString="" />
<add name="TestDBConnectionString" connectionString="" />
now in the code i do:
[code]...
I get: The ConnectionString property has not been initialized. What am I doing wrong? AFAIK this should get the value I want...
I don't want to do in connections section as I WANT TO BE SURE that I don't mess up the production server since I'm in the same network...

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:

My Question is can we extend one context to another in Entity Framework 4. Following is the problem background.
I am using EF4 for developing a Web-Application. My Web Application has 3 projects.
One project is for storing candidate CV information.
Another project is for storing customer information.
Final project is called CORE. this CORE contains a edmx file that should be extended by CV and CRM.
As an example email address table can be shared by both customer (CRM) and CV. To share one table with another, we should be able to extend one context (CV context) with other context (customer context). Could some one having experience using Entity Framework share your experience with me to find whether this is possible.
We have 3 edmx files in three class libraries:
Person class library(Core) with core.edmx-Basic details related to a person(name, email) CV Class library with CV.edmx wich have CV related data(Experiance,skills) Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project

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?

I recently started explore MVC and just tried some samples around, i.e. MvcMusicStore.
As the sample DB in MvcMusicStore is quite small, I am wondering how should I design the edmx/entity for a bigger database, let say for an enterprise application, which has more than 20 tables as in AdventureWorks?
Thus, the question is should I include all in one edmx/entity or I should include multiple edmx/entities when I designing the model?

I'm using Fluent NHibernate and need to get my Connection String from the connection.connection_string property on hibernate.cfg.xml file to create my Session Factory:
private static ISessionFactory SessionFactory {
get {
return = Fluently.Configure()
.Database(MySQLConfiguration.Standard.ConnectionString(c => c.FromConnectionStringWithKey("MyConnStr")))
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<FooMap>())
.ExposeConfiguration(c => c.Properties.Add("hbm2ddl.keywords", "none"))
.BuildSessionFactory();
}
}
I want to replace MyConnStr (that is in my web.config file) "c => c.FromConnectionStringWithKey("MyConnStr")" for the connection string from the hibernate.cfg.xml file.
I've tried use NHibernate.Cfg.Environment.ConnectionString, but it didn't work.

I am having trouble connecting to a ms sql database on the server. The hosting company said that the .sql file was imported successfully, but when I try to use the 'login' or 'create account' features im getting an error page saying:
Failed to generate a user instance of SQL Server due to failure in retrieving the user's local application data path. make sure the user has a local user profile on the computer. The connection will be closed.
I am sure all the connection info is correct so it is really frustrating trying to work the problem. I have listed the connection string in my web.config file to see if anyone can see anything wrong with it.

I'm using Visual Studio 2008 and SQL Server 2008 Developer to create a website.
I'm trying to test a connectino to a local database in my computer.
What I did is create a connection string in the webconfig file like this:
[Code]....
Then I want to call that connection string like this in the default.aspx.cs file I write the following code:
[Code]....
I'm not getting any error or warning in any of the code but when I run the page I throws me an error telling me:
The connectionstring property has not been initialized.
If I run with debug on it shows this:
[Code]....
Line 22 in red.
I don't know what I'm doing wrong since VIsual Studio does not tell me there is an error, it just seems like it cannot make the connection.

We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).
The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
Dim cd As New System.Data.OleDb.OleDbCommand("SELECT * FROM " & strCSVFilename, cn)
cn.Open()
da.SelectCommand = cd
da.Fill(dtData)
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string. What am I missing here?

I'm running into a really annoying problem with my Linq to SQL project. When I add everything in under the web project everything goes as expected and I can tell it to use my existing connection string stored in the web.config file and the Linq code pulls directly from the ConfigurationManager.
This all turns ugly once I move the code into its own project. I've created an app.config file, put the connection string in there as it was in the web.config but when I try to add another table in the IDE keeps forcing me to either hardcode the connection string or creates a Settings file and puts it in there, which then adds a new entry into the app.config file with a new name.
Is there a way keep my Linq code in its own project yet still refer back to my config file without the IDE continuously hardcoding the connection string or creating the Settings file? I'm converting part of my DAL over to use Linq to SQL so I'd like to use the existing connection string that our old code is using as well as keep the value in a common location, and one spot, instead of in a number of spots.
Manually changing the mode to WebSettings instead of AppSettings works untill I try to add a new table, then it goes back to hardcoding the value or recreating the Settings file. I also tried to switch the project type to be a web project and then rename my app.config to web.config and then everything works as I'd like it to. I'm just not sure if there are any downfalls to keeping this as a web project since it really isn't one. The project only contains the Linq to SQL code and an implementation of my repository classes.
My project layout looks like this
[code]....
Every time I try to make the default constructor look like the first way, it always auto changes back to the second way once I make a change to the file unless the DBML is inside of a web project.

I will explain the my current yet simple architecture of my application(s). At the moment I have my main web application as a separate project. I then reference the CoreBLLDAL (Business Logic and Data Access) Project so that several projects can have access to the BLL/DAL Project.
Within the CoreBLLDLL Project I use TableAdapters for my DAL.
I have just upgraded to VS2010 and I would like to make use of the Config Transforms, allowing me to have a separate web.config for test and production - however, TableAdapter get the connection string from the Settings.settings file.
How can I change the TableAdapters to get the connection string from the app/web.config file? I read that you can change this within the designer file for the TableAdapters by using ConfigurationManager, however, I tried this but I do not have access to the ConfigurationManager namespace. I presume this is because the project is a class library and not a web application - I am not too sure.
