No default service level objective found of edition "GeneralPurpose"

Hi all I got this issue while deploying my .net web application into Azure . In my application I was creating the Database by EnityFramework Code first approach . So after deploying the application to azure ,I changed the connection string . Then when I run my application , I see this error message "No default service level objective found of edition"GeneralPurpose".
 This was my connection string.

 
<connectionStrings>
        <add name="CodeFirstDataBase" connectionString="Data Source=tcp:mysite.database.windows.net,1437;Initial Catalog=SchoolCodeFirstDB; User ID=testn;Password=admin;Integrated Security=false;MultipleActiveResultSets=True;App=EntityFramework;" providerName="System.Data.EntityClient" />
 </connectionStrings>

 So I investigated a lot but could not get a exact solution for it . But this fix worked for me .

I just changed  the connection string provide name from providerName="System.Data.EntityClient" to  providerName="System.Data.SqlClient" and it worked fine for me .
So this would be the resulted connection string .
<connectionStrings>
        <add name="CodeFirstDataBase" connectionString="Data Source=tcp:mysite.database.windows.net,1437;Initial Catalog=SchoolCodeFirstDB; User ID=testn;Password=admin;Integrated Security=false;MultipleActiveResultSets=True;App=EntityFramework;" providerName="System.Data.SqlClient" />
 </connectionStrings>

 Please share your comments please .

This error is generally produced while you working on the  Linq query with Entity framework and there was some other system configurations like Visual studio 2015. Entity framework version 4. C# 4.5 But while I checked the Inner exception I got the following message  "There is already an open DataReader associated with this Command which must be closed first" So in my case there was some WCF services and from the WCF services I was extracting the data by Linq query .
