SQLite Entity Framework without App.config

It is necessary to use the SQLite Entity Framework Database-first approach for the 3d-party application plugin. I searched all the Internet, including Add a DbProviderFactory without an App.Config, http://ift.tt/1X7l4SI and many other. I have tried to use them all in different ways and combinations, but nothing helps:

"An unhandled exception of type 'System.Data.Entity.Core.MetadataException' occurred in mscorlib.dll. Additional information: Schema specified is not valid. Errors: AutosuggestModel.ssdl (2,2): error 0152: No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SQLite.EF6'. Make sure the provider is registered in the 'entityFramework' section of the application config file."

There is a test console application in the solution. With this minimal App.config it works:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://ift.tt/1eigFsq -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <entityFramework>
    <providers>
      <provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
    </providers>
  </entityFramework>
  <system.data>
    <DbProviderFactories>
      <add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
    </DbProviderFactories>
  </system.data>
</configuration>

The connection string has already implemented in the code. Used packages are:

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="EntityFramework" version="6.1.3" targetFramework="net452" />
  <package id="System.Data.SQLite" version="1.0.98.1" targetFramework="net452" />
  <package id="System.Data.SQLite.Core" version="1.0.98.1" targetFramework="net452" />
  <package id="System.Data.SQLite.EF6" version="1.0.98.1" targetFramework="net452" />
  <package id="System.Data.SQLite.Linq" version="1.0.98.1" targetFramework="net452" />
</packages>

Please, give all the required code and specify where to insert it. Thanks in advance.
