How to solve C# - SQlite provider problem

I have tried all the solutions but I get this error;
System.NotSupportedException: 'Unable to determine the provider name for provider factory of type 'System.Data.SQLite.SQLiteFactory'. Make sure that the ADO.NET provider is installed or registered in the application config.'
I have installed all packages and dll's.picture of references
and my App.config;
<configuration>
<configSections>
<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.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
<provider invariantName="System.Data.SQLite.EF6" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
<provider invariantName="System.Data.SQLite" type="System.Data.SQLite.EF6.SQLiteProviderServices, System.Data.SQLite.EF6" />
</providers>
</entityFramework>
<system.data>
<DbProviderFactories>
<remove invariant="System.Data.SQLite" />
<add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
<remove invariant="System.Data.SQLite.EF6" />
<add name="SQLite Data Provider (Entity Framework 6)" invariant="System.Data.SQLite.EF6" description=".NET Framework Data Provider for SQLite (Entity Framework 6)" type="System.Data.SQLite.EF6.SQLiteProviderFactory, System.Data.SQLite.EF6" />
</DbProviderFactories>
</system.data>
<connectionStrings><add name="mainEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SQLite.EF6;provider connection string="data source=C:\Users\MONS\Desktop\XmltoCsvBeta\XmltoCsvBeta\bin\Debug\Data\DB.db"" providerName="System.Data.EntityClient" /></connectionStrings></configuration> ```

In case the error pops up at runtime why making selections it may mean that System.Data.SQLite.Linq package is missing in project's references. System.Data.SQLite includes support for LINQ so it is enough to install this one (instead of just System.Data.SQLite.Core).
This helped in my case at least.

Unable to determine the provider name for provider factory of type “System.Data.Sqlite.SqliteFactory”

Unexpected exception occurred when generating the model. See output window for more details. Exception message: 'NotSupportedException: Unable to determine the provider name for provider factory of type 'System.Data.SQLite.SQLiteFactory'. Make sure that the ADO.NET provider is installed or registered in the application config.'.
The above error occurs when I try and simply refresh my model (in the designer for my edmx file). I have a DB that I created, but I was trying to add a table when I first got this exception. Now, simply refreshing the model causes the exception. To the best of my knowledge, I haven't modified anything else.
I've googled the hell out of this, but I'm at my wits end.
I'm using VS2017, EF6 and SQLite (v3 I think).
Here is my App.config:

There is an issue with EF 6.2 which came along with the Visual Studio 2017 15.7 update that prevents the EDMX being generated with SQLite.
The work around is to add the following to machine.config in the system.data -> DbProviderFactories section.
<add name="SQLite Data Provider" invariant="System.Data.SQLite" description=".NET Framework Data Provider for SQLite" type="System.Data.SQLite.SQLiteFactory, System.Data.SQLite" />
My full section now looks like this
<system.data>
<DbProviderFactories>

I was facing the same issue with visual studio 2017 version 15.7.5 .I did every thing but nothing worked . I think this issue remains till version 15.8.0 is released . Once I updated the the visual studio 2017 version to 15.9.12 (current version) , This is resolved now .
Please find the yellow notification flag on the top of your visual studio , click there and update your visual studio version .

EntityFramework 6 with Sqlite - design time error

I want to use EF6 with Sqlite. I follow up the instruction I found here: http://erikej.blogspot.de/2014/11/using-sqlite-with-entity-framework-6.html
If I now add a new entity model I get some strange error and I found nothing on the Internet to resolve it. :(
Translated it means some think like:
"The SelectCommand-Property has not been init befor the call of: 'Fill'."
I checked all references and all NuGet packages are up to date.

Somebody knows more about it? Please help.

System.data.Sqlite with EF6

I'm working on a project that involves connecting SQLite with EF 6 in a database-first approach. I've installed System.Data.SQLite (and ensured that their DLLs were in the GAC), and added the dependencies to my project using NuGet. However, when I attempt to create a schema (via the Entity Data Model Wizard) for an already-existing database, I get the error
Your project references the latest version of Entity Framework; however, an Entity Framework database provider compatible with this version could not be found for your data connection. Exit this wizard, install a compatible provide, and rebuild your project before performing this action.
I've tried the answers in this thread, but the fixes that did not involve creating the DAO classes by hand do not seem to help. Since the database that I'm connecting to is quite large (schema-wise), recreating the schema in code is not reasonable for me.
My App.config follows.
<?xml version="1.0" encoding="utf-8"?>
<configuration>

I don't entirely understand what VS is complaining about, as it appears that System.Data.SQLite has properly bound itself into VS, and that the config file contains the requisite information to allow VS to find it to access the DB. However, I missed something, and I can't figure out what.

This is my application configuration that was successful for me.

THIS project also references an identical configuration to my own.

SQLite 1.0.91.3 and EntityFramework 6.0.2 in VisualStudio 2013 project register sqlite

I create project with entityframework 5 and SQLite 1.0.91.3 and create entity data model. But after update entity to entityframework 6.0.2 I have error:
Error 175: The ADO.NET provider with invariant name 'System.Data.SQLite' is either not registered in the machine or application config file, or could not be loaded. See the inner exception for details.
