I have spent several hours trying to search this on the web in addition to calling and emailing support at 1and1.com web hosting with no success.
I have ASP.NET pages which connect to MS SQL Server database using the entity framework. On my local machine, all works fine (naturally). However, when I modify the connection string in my web.config to point to my SQL Server database on 1and1.com, I get the following error:
"Unable to load the specified metadata resource."
Here's my current connection string (as defined in my web.config file):
<add name="TimeDataLicenseEntities"
providerName="System.Data.EntityClient"
connectionString="metadata=res://*/
Model1.csdl|res://*/
Model1.ssdl|res://*/
Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=dbXXXX.db.1and1.com,1433;
Integrated Security=false;
initial catalog=database_name;
user id=dboXXXX;
password=valid_password;multipleactiveresultsets=True"" />
(Please note that where there are 'XXXX' the values are different in the actual config file as well as for 'database_name' and 'valid_password')
I'm using the Entity Framework in the code so I'd prefer solutions that correct the content of my web.config file.
Here is what ended up working for me:
<add name="TimeDataLicenseEntities"
providerName="System.Data.EntityClient"
connectionString="metadata=
res://<assemblyname>/Model1.csdl|
res://<assemblyname>/Model1.ssdl|
res://<assemblyname/Model1.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=dbXXXX.db.1and1.com,1433;
Integrated Security=false;
initial catalog=database_name;
user id=dboXXXX;
password=valid_password;
multipleactiveresultsets=True"" />
By including the assemblyname for my code in the sections above (the brackets ('<' and '>') should not be included), I was able to finally get it to work.
Thanks all for your assistance.
Here is what actually works on 1and1 server from ASP.NET Code first design. So, simply replace your serverName, DatabaseName, UserID, and Password.
<add name="DefaultConnection"
connectionString="Data Source=dbXXX.db.1and1.com,1433;Initial Catalog=dbYYYYY;Integrated Security=False;user id=dboZZZZZ;password=YOURDBPASSWORD;MultipleActiveResultSets=True;Application Name=EntityFramework"
providerName="System.Data.SqlClient" />
Hope this can help anyone looking to use 1and1 asp.net server since their customer service is pretty useless.

I just create a new ASP MVC sample. The code was generate with scaffolding. Then I run the application and it runs smooth. But when I click "Register" link in top nav bar and tries to register it does not work.
My Connection String:
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-ProductExample-20151218101004.mdf;Initial Catalog=aspnet-ProductExample-20151218101004;Integrated Security=True" providerName="System.Data.SqlClient" />
It is saying that your connection with sql server is not established.
Please check your connection string.
Here i am showing mine. Please check it once. It may help you.
<connectionStrings>
<add name="DemoEntities" connectionString="metadata=res://*/Models.Report.DemoEntities.csdl|res://*/Models.Report.DemoEntities.ssdl|res://*/Models.Report.DemoEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=192.168.1.2\SQLEXPRESS;initial catalog=DEMODB;user id=abc;password=abc;multipleactiveresultsets=True;application name=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
Check all following parameters are correct or not.
data source=192.168.1.2\SQLEXPRESS;
initial catalog=DEMODB;
user id=abc;
password=abc;
According to your sql server configuration you need to correct your connection string.
I needed to write IP\InstaceName may be in your you only need to write IP or only instace name. Please check it once.
check sql server express is install or not on your machine if not then use local sql server that is install on your machine and change connection string
data source=.;
initial catalog=DEMODB;
user id=abc;
password=123;
I have an azure website and database. I'm running an ASP.NET MVC 4 / EF 5 app localy and trying to put some data to the azure database before to deploy the app. But I have a TargetInvocationException : {"The ASP.NET Simple Membership database could not be initialized. For more information, please see http://go.microsoft.com/fwlink/?LinkId=256588"}
Keyword not supported : server
This is the connection string that I get from my azure dashboard :
<add name="myconstring" connectionString=Server=tcp:myserver.database.windows.net,1433;Database=mydatabase;User ID=cdptest#myserver;Password=******;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" providerName="System.Data.EntityClient" />
I tried this I got "Keyword not supported : data source"
<add name="myconstring" connectionString="Data Source=myserver.database.windows.net;Initilal Catalog=mydatabase;User ID=cdptest#myserver;Password=*****;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" providerName="System.Data.EntityClient"/>
The following works for me:
<add name="coupdpoAPEkowswAEntities" connectionString="Server=tcp:myserver.database.windows.net,1433;Database=mydatabase;User ID=cdptest#myserver;Password=*****;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;" providerName="System.Data.EntityClient"/>
Use Server instead of Data Source, and specify the protocol and the port, and use Database instead of Initial Catalog
OK the providername was wrong. System.Data.SqlClient was excepted as this is a code first app model.
I probably got System.Data.EntityClient from another app with Model First or Database First...
How can I use an .mdf file (called SQL Server Database in VS2012) for Entity Framework?
I get this error message:
Invalid value for key 'attachdbfilename'.
This is my connectionstring:
<add name="DbContainer" connectionString="metadata=res://*/Database.Db.csdl|res://*/Database.Db.ssdl|res://*/Database.Db.msl;provider=System.Data.SqlClient;provider connection string="data source=(LocalDb)\v11.0;initial catalog=DataContext;Integrated Security=True;AttachDBFilename=|DataDirectory|\DataContext.mdf;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />.
In Global.asax.cs, Application_Start I set the correct path for |DataDirectory| like this:
string newPath = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "App_Data");
AppDomain.CurrentDomain.SetData("DataDirectory", newPath);
Do any of you know to make this work?
Btw. it works when running my web application locally (i.e. debug), and does not work when publishing to my online domain.
If it works locally but not online, the problem is from data source part of your connection string. And if you want to attach your db at runtime, not by management studio, remove the initial catalig part. So change it to something like the following:
<add name="DbContainer"
connectionString="metadata=res://*/Database.Db.csdl|res://*/Database.Db.ssdl
|res://*/Database.Db.msl;provider=System.Data.SqlClient;
provider connection string="data source=RemoteServerInstance;
Integrated Security=True;AttachDBFilename=|DataDirectory|\DataContext.mdf;
MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
After spending 6 hours today to get a connection with my SQL Server 2012 database from Visual Studios 2012, I give up.
Setup:
Database: App_Data/GameDB.mdf
DB Location: C:\Users\USERNAME\Documents\Visual Studio 2012\Projects\ProjectRawWar\ProjectRawWar\App_Data\GameDB.mdf
Connection string:
<add name="LocalSqlServer"
connectionString="Data Source=(LocalDB)\v11.0;Initial Catalog=GameDB;Integrated Security=False;"/>
I first tried a SQL Server Compact database, didn't work.
I tried many other connection strings from connectionstrings.com, didn't work.
I tried to put the full path of the database in the connection string, didn't work.
Can someone please help me out of my misery?
Update:
I just followed http://msdn.microsoft.com/en-us/library/aa983322.aspx.
The database is there. I copied the connection string from the wizard right into my webconfig connectionstring, still doesnt work. Why? Where is the logic?
Reading your question I am getting the feeling that you are trying to connect to a database file. While you can do that with Access "Databases" it is not possible with SQL Server databases. The file needs to be mounted or attached to SQL Server first.
Check out this MSDN article for details: http://msdn.microsoft.com/en-us/library/ms190209.aspx#SSMSProcedure
If you're going to disable integrated security, then you need to provide a username and password.
IE:
Server=127.0.0.1;User ID=useridhere;Password=passwordhere;database=dbnamehere
Be sure to make sure the userid and password you specify has access to the database you need. For testing, you can use the 'sa' account, but that's a poor long-term solution for major security reasons.
Ok I fixed it myself.
How I did it:
Delete every .sdf and .mdf file.
Just made following connection strings:
`<add name="DataContext"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\GameDB1.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />
<add name="LocalSqlServer"
connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\GameDB1.mdf;Integrated Security=True"
providerName="System.Data.SqlClient" />`
Visual Studio created my database using my DBContext.
Thanks all for the information.
I am trying to publish a website using ASP.NET MVC3 EF and CODEFIRST with a SQL Server 2008 backend. On my local machine I was using a sql express db for development, but now that I am pushing live, I want to use my hosted production database. The problem is that when I try to run the application, it is still using my local db connection string. I have completely removed the old connection string from my web.config file and am using the <clear /> tag before creating the new connection string. I have also cleaned the solution and rebuilt, but somehow it is still connecting to the old db. What am I missing?
This is the new connection string:
<connectionStrings>
<clear />
<add name="CellularAutomataDBContext"
connectionString=" Server=XXX;
Database=CellularAutomata; User ID=XXX; Password=XXX; Trusted_Connection=False"
providerName="System.Data.SqlClient" />
</connectionStrings>
UPDATE
When I debug and look at the DBCONTEXT object, this is what is showing up for its connection:
Data Source=.\\SQLEXPRESS;Initial Catalog=CellularAutomata.Models.D1K2N3CARuleDBContext;Integrated Security=True;MultipleActiveResultSets=True"
I am unsure why this is happening because I cannot find it being set to this anywhere. Also, under configuration it says LazyLoadingEnabled = true, I assume this may be part of the problem, maybe it is not loading the new connection string. Where do I change these parameters?
UPDATE 2
EFCodeFirst is using a default connection string, I can't figure out how to get it to accept the connection string that I specify in the web.config file.
So, When using EF CodeFirst, there is a default connection string that it uses. If you want to be able to use a custom connection string, there are a few parameters guidelines that you must follow.
name ="this must match the name of your database context class"
connectionString="Server=yourserverurl; Database=yourdatabasename; User ID=youruserid;
Password=yourpassword; Initial Catalog=the name of the database to use;
Trusted_Connection=False"
providerName="System.Data.SqlClient"
So far this is working for me.
The connectionString you show is not an EF connection string. The EF won't use it. So you're changing the wrong thing.
An EF connectionString will include providerName="System.Data.EntityClient"
It will look for the same name as your context and depending on what else you
are using other names as well. I usually use the following for controlling
specific features with either the same or specific connection strings
(I keep app services in a different db for example so EFCF can drop tables as needed):
<connectionStrings>
<add name="MyAppContext" .../>
<add name="ApplicationServices" .../>
<add name="DefaultConnection" .../>
</connectionStrings>
