I'm working in a desktop application with SQLite as its database.
i'm working with EF6 -no Entity F Core- in Visual Studio CE.
This is my app.config from my console application
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>

And when I'm trying to test this code:

</DbProviderFactories>
</system.data>
</configuration>
But when I build the project this meesage appears:
The Entity Framework provider type 'System.Data.SQLite' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SQLite' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.
¿How to fix it?
Thanks for any support

There is no web.config file under /Portals/_default/2sxc
Platform and 2sxc version:
DNN Evoq Content 08.04.02 (5) (both local and Azure based installation exhibit same errors)
2sxc 8.5.4
So, I have created a console application, added the entity framework nuget package, created a dbcontext and enabled migrations for my project.
However, I don't see the database anywhere. The database exists since I can query it when I run the application but since I haven't entered a connection string I don't see it anywhere in my SQL Management Studio.
My question is, where do Visual Studio "hide" this database?
Btw, I'm using EF6 Code First.
EDIT: Here is my app.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
Add this to constructor of the context to see the default connection string used.
public class MyContext : DbContext
{
public MyContext()
{
Console.WriteLine(this.Database.Connection.ConnectionString);
}
}
Usually it creates the database in v11.0 or mssqllocaldb(in you app.config it is mssqllocaldb) instance of sqllocaldb.
The database file can be located at Users folder(Windows 8.1):
C:\Users\{UserName}\ApplicationName.ContextName.mdf
I generated a script for my aspnet Database, now when I try to use the database it gives an error
The 'System.Web.Security.SqlMembershipProvider' requires a
database schema compatible with schema version '1'. However,
the current database schema is not compatible with this version. You
may need to either install a compatible schema with aspnet_regsql.exe
(available in the framework installation directory), or upgrade the
provider to a newer version.
What options do I really have to solve this problem?
Do I need to run aspnet_regsql.exe or is there a way to get around this error besides having to go with this option as the error suggests?
My web.config file looks like this:

I would use the aspnet_regsql.exe to create a new/blank database.
Then you could use this:
http://granadacoder.wordpress.com/2007/11/29/membershipprovider-helper-to-transfer-data/
It will "create tsql code" so you can move all your data into your blank database.
I had similar error, 'simple' solutions like closing the project and re-opening, rebuilding, resolves the error. that's if you're sure you did everything correctly
I am creating a WPF application, having classical architecture: UI layer, business logic layer and infrastructure layer. I decided to split configuration in two files: app.config file, containing common app configuration, and dll.config, containing connection string to use in DbContext for domain model storage. The second .config file should be sticked to business logic DLL, while first file sticked to corresponding UI executable (there will be one more UI with it's own configuration).
app.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<enterpriseLibrary.ConfigurationSource selectedSource="Winter DAL Configuration">
<sources>
<add name="Winter DAL Configuration" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
filePath="dll.config" />
</sources>
</enterpriseLibrary.ConfigurationSource>
</configuration>
dll.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<dataConfiguration defaultDatabase="WinterContext" />
<connectionStrings>
<add name="WinterContext" connectionString="Data Source=Winter.sdf"
providerName="System.Data.SqlServerCe.4.0" />
</connectionStrings>
</configuration>
Now, when I'm starting the app, DbContext throws an exception saying it cannot find connection string with specified name. If I move connection string from dll.config to app.config - all working fine.
Maybe I must explicitly load configuration somehow? Or?.. What do I do wrong?
Thx in advance!
Based on the config files supplied, Entity Framework went looking in app.config of root in start project and didnt find the EF content. Especially the Connection string.
When you first used UF it would have created such entries, perhaps in the model project.
IM using EF5.0 so careful with cut and paste on Entity Section .
<configuration>
<configSections>

<add name="CONTEXT_NAME_HERE"
providerName="System.Data.SqlClient"
connectionString="Data Source=YOURDB_SERVER;Initial Catalog=YOUR_DBNAME;Integrated Security=True;MultipleActiveResultSets=True;App=EntityFramework" />
</connectionStrings>
</configuration>
I hope I understood your question, you want to structure your app.configs as a hierarchy, which is valid, in web applications that is very common, the easiest way to let .net help you with the merging is specifiying the regions of app.config in all those configurations that need to be bounded, and in the inner configurations you can override the values until you have the last one, for example:
ROOT APPCONFIG
<configuration>
<commonCollection>
<add key="first" value="1" />
<add key="second" value="2" />
<add key="third" value="3" />
</commonCollection>
</configuration>
INNER APPCONFIG
<configuration>
<commonCollection>
<remove key="first" />
<add key="first" value="10" />
</commonCollection>
</configuration>
Results:
ROOT APPCONFIG
first : 1
second: 2
third: 3
INNER APPCONFIG
first: 10
second: 2
third: 3
EDIT
for your EF context, to set the connection string in the constructor :
public MyContextDB() :base("name=DefaultConnection")
{
//other initializers
}
hope it helps,
This is a WPF app which references an Entity Framework class library. In the App.config of the class library project I have this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
</entityFramework>
</configuration>
All very standard. What I want to do is to add a connection string which will enable me to connect to remote server via a URL to the database. Is this going to be possible?
I've tried something like this:
<connectionStrings>
<add name="LanguageEntities" connectionString="metadata=res://*/LanguageModel.csdl|res://*/LanguageModel.ssdl|res://*/LanguageModel.msl;provider=System.Data.SqlClient;provider connection string="data source=http://www.myweb.net:667;User ID=Remote;Password=cleverstring;initial catalog=LanguageModel.LanguageEntities;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
But my app seems to default to the local connection without giving me an error message.
Any suggestions gratefully received.
Many thanks!
