Assembly manifest mismatch package-install doesn't resolve

The manifest error is not resovled, i try my best (even link Roslyn source code to my project ). Below is the portion of code, which generate error. The project is WINFORM and in Element Host load the Roslyn Assembly.

Steps to Reproduce the error

1. remove all packages from the solution Get-Package | Uninstall-Package -RemoveDependencies -Force

2. set framework to 4.7.2 and Build Platform: x86

3. remove all System.* referencess
4. add references System, System.Drawing, System.Windows, System.Windows.Forms, System.Data
5. install package roslynPad.Editor ( latest: i.e. 1.0.4 ) 5.1. install package roslynPad.Windows ( latest: i.e. 2.4.0 ) 5.2. install package roslynPad.Roslyn ( latest: i.e. 2.4.0 )
6. reference PresentationCore, PresentationFramework, WindowsBase, WindowsFormsIntegration, UIAutomationProvider
7. Goto Reference Dlls select all ( in visual studio ), and make Copy Local = true.
8. ReBuild and found 23 ( conflicts between different versions ) warnings.
9. Check detail build log ( verbosity is set to detailed )

9** Stackoverflow suggested: recompile assemblies on some posts. remove all packages and add source of roslynPad.

10 do the following, add sources and reset dependencies

Set Refrence to above projects sources.

Resolved by changing the following in app.config

 <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />

whatever the bindingRedirect is on app.config, remove all. recompile and add the missing packages. tada the solution is working.
