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 am having problem in running my ASP.Net MVC project which is an admin project. It connects with a sql server database to fetch record. When I try to build and run, I am welcomed with this error: "Unable to find requested .Net Framework Data Provider. It may not be installed".
Here is the link to this error.
I have tried many solutions available on stackoverflow but none of them worked for me that's why I am posting this question here again. I tried changing the Target Framework version in Properties of project to all the available versions but all in vain. Here is the screenshot of my Global.asax.cs file which is causing this exception.
Below is the connection string of my project:
<add name="AlkhaleejEntities" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=Alkhaleej;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient"/>
Connection string provided above indicates EF connection provider being used:
connectionString="metadata=res:///Models.Model1.csdl|res:///Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=Alkhaleej;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient"
Note that SimpleMembershipProvider can't use EF provider connection string (see this post) due to usage of SqlClient provider instead of EntityClient, hence it requires SQL Server connection string to interact with database.
Try open Server Explorer => Data Connections => right click your server connection, select Properties => add provided SQL Server connection string something like this one (leave EF connection string part as is, just add SqlClient provider connection string):
<add name="DefaultConnection" connectionString="Data Source=.;Initial Catalog=Alkhaleej;Integrated Security=True" providerName="System.Data.SqlClient" />
Then, change connectionStringName parameter on WebSecurity.InitializeDatabaseConnection method inside SimpleMembershipInitializer class to SQL Server connection string name as given below:
public class SimpleMembershipInitializer
{
public SimpleMembershipInitializer()
{
// other code part
if (!WebSecurity.Initialized)
{
WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "Email", autoCreateTables: true);
}
}
}
NB: The ideal setup for EF projects should include at least one SqlClient connection string and one EntityClient connection string, which may serve different providers with same target database.
Similar issues:
SimpleMembershipInitializer won't initialize
Unable to find the requested .Net Framework Data Provider. (SqlClient)
Can SimpleMembership and Entity Framework share a connection string?
I have a weird issue occuring when using table adaper connection strings in a .net 4.0 web application.
I'm using the same connection string name with different server/credentials for the test
and production environments. I comment out the connection string that I'm not using(see example
below) I'm having an issue with the table adapter not using the current connection string that is uncommented in the web config file. For example, I make any changes against the test database using the test connection string. However, when I uncomment the production connection string(and comment the test connection string) and deploy to the production server, the test connection is still being used. Some of the connections are not defined in the code behind - some are grids that are bound to objectdatasources. Can anyone offer any advice on to fix this problem?
<!-- Test Conn -->
<add name="Connection1" connectionString="Data Source=server1; Initial Catalog=database1; User ID=username1; Password=password1" providerName="System.Data.SqlClient"/>
<!-- Production
<add name="Connection1" connectionString="Data Source=server2; Initial Catalog=database1;User ID=username2; Password=password2" providerName="System.Data.SqlClient"/>
-->
Try restarting IIS after you deploy.
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 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!
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..
