I want to use SimpleMembership in an MVC 3 website, but I'm getting the following error:
System.ArgumentException was unhandled by user code. Unable to find the requested .Net Framework Data Provider. It may not be installed.
I'm using a SQL Server database, through Entity Framework. Here is my connection string:
<add name="Database1Entities" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\Database1.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
I already use EF in other parts of the application, so this connection string is correct and I have connection to the database. Can you please help?
I had the exact same problem. The work around I found was to take out that "metadata=..." part of the connection string and put in just the connection string information. My look similar to this:
<add name="Membership" connectionString="Data Source=serverName;Database=databaseName;User ID=userId;Password=aPassword;Trusted_Connection=False;Encrypt=True;" providerName="System.Data.SqlClient" />
Hope that helps!

I am using Entity Framework v6.4.4 database first in an ASP.NET Framework v4.6.2 application. This is my connection string entry in web.config:
<add name="MyApplicationEntities" connectionString="metadata=res://*/Models.MyApplication.csdl|res://*/Models.MyApplication.ssdl|res://*/Models.MyApplication.msl;provider=System.Data.SqlClient;provider connection string="data source=*****;MultiSubnetFailover=True;initial catalog=****;persist security info=True;ApplicationIntent=READONLY;user id=****;password=****;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
If ApplicationIntent=READONLY is in the connection string then I get an exception when I try to access the database:
The underlying provider failed on Open --> The wait operation timed out.
otherwise everything is fine.
I have seen this answer - https://stackoverflow.com/a/21241299/1471850 - but this doesn't help. Does anyone know what the issue might be?
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...
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.
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" />
Im trying to user ASP.NET MVC3 with Entity Framework and ASP.NET Membership for authentication. I've set up an existing database as my application services database for membership.
When i create the entity data model through the wizard it adds the following connection string to my web.config.
<add name="DBEntities" connectionString="metadata=res://*/Models.DB.csdl|res://*/Models.DB.ssdl|res://*/Models.DB.msl;provider=System.Data.SqlClient;provider connection string="Data Source=PM\SQLEXPRESS;Initial Catalog=DB;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
I'm a noob so i don't really understand why but i tried using the same connection string for my membership provider and failed (probably because of this: providerName="System.Data.EntityClient" ?).
So i added a separate connection string to the same database and used it for the membership provider.
<add name="ApplicationServices" connectionString="Data Source=PM\SQLEXPRESS;Initial Catalog=DB;Integrated Security=True" providerName="System.Data.SqlClient"/>
It works fine when i use ASP.NET configuration to add user and etc. But when i run the application and try to do something like validating a user i get an error;
A transport-level error has occurred when receiving results from the server. (provider: Shared Memory Provider, error: 0 - The handle is invalid.)
I made a guess this has something to do with my connection strings. I'm hoping some of you experts can help. Cheers.
Have you tried restarting the server : A transport-level error has occurred when receiving results from the server ?
Not a solution or an answer, just a pointer to a similar issue..
