'No Entity Framework provider found' for EF 6 and SQLite 1.0.96.0

Question

I realize there are already several similar questions on this topic, but many of them are from older version of SQLite which did not fully support EF 6 as far as I am aware.

Answer 1

I solved same error with just add a single line in App.config

<provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6"/>

PS: Add provider to <configuration> > <entityFramework> > <providers>

Answer 2

I finally got it too work

I'm using : EF 6.1.3 http://www.microsoft.com/en-us/download/details.aspx?id=40762 and System.Data.SQLite 1.0.96.0 sqlite-netFx451-setup-bundle-x86-2013-1.0.96.0.exe

I followed the description written in: Database first create entity framework 6.1.1 model using system.data.sqlite 1.0.93 (in this description a nuget package of entity framwork is installed -i did it too)

For the app.config file i used these fixes: https://stackoverflow.com/a/24324212/885349 (written by tomexou)

Finally SQLite Connector wasn't shown in the ADO.Net Entity Data Model Mapper

The missing link was the \bin folder. I had to set the "Copy Local" = true setting for following dlls:

• SQLite.Designer
• System.Data.SQLite
• System.Data.SQLite.EF6
• System.Data.SQLite.Linq

Only for completeness - added through Nuget and also in \bin folder

• EntityFramework
• EntityFramework.SqlServer

And the SQLite Connection was shown...

Answer 3

After searching for a week i believe this problem is a feature in development by the sqlite team.

More information can be found here SQLite connection not appearing in Entity Data Model Wizard

edit: Maybe looking into some different providers might seem worthwhile. Although i have not tested this myself, http://www.devart.com/dotconnect/ offers some promising alternatives and states EF compatibility.

Answer 4

public class EFConfiguration : DbConfiguration
{
    public EFConfiguration()
    {
        SetDefaultConnectionFactory(new LocalDbConnectionFactory("v.11"));

        //HACK
        var EF6ProviderServicesType = typeof(System.Data.SQLite.EF6.SQLiteProviderFactory).Assembly.DefinedTypes.First(x => x.Name == "SQLiteProviderServices");
        var EF6ProviderServices = (DbProviderServices)Activator.CreateInstance(EF6ProviderServicesType);
        SetProviderServices("System.Data.SQLite.EF6", EF6ProviderServices);
        SetProviderServices("System.Data.SqlClient", System.Data.Entity.SqlServer.SqlProviderServices.Instance);
        SetProviderFactory("System.Data.SQLite.EF6", System.Data.SQLite.EF6.SQLiteProviderFactory.Instance);
        SetProviderFactory("System.Data.SQLite", System.Data.SQLite.SQLiteFactory.Instance);
    }
}

Answer 5

Try these tweaks:

<providers>
  ...
  <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6"/>
</providers>

<system.data>
    <DbProviderFactories>
        <remove invariant="System.Data.SQLite.EF6" />
        <add name="SQLite Data Provider" invariant="System.Data.SQLite" description="Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
    </DbProviderFactories>
</system.data>

Answer 6

Here is a working app.config

<?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" />
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
  </startup>

  <entityFramework>
    <providers>
      <provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6"/>
    </providers>
  </entityFramework>

  <connectionStrings>
    <!-- use AppDomain.SetData to set the DataDirectory -->
    <add name="MapDbConnectionStr" connectionString="Data Source=|DataDirectory|MapDb.sqlite" providerName="System.Data.SQLite" />
  </connectionStrings>

  <system.data>
    <DbProviderFactories>
      <remove invariant="System.Data.SQLite.EF6" />
      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description="Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
    </DbProviderFactories>
  </system.data>



</configuration>
