I have a Windows service application made with VB.NET under Visual Studio 2013 and using NET Framework 4.5. I am using Nuget in this project.
Once I build the solution (it builds successfully) I get below warning messages in the results window:

I have been searching for information about this, and I have found some posts and blogs talking about that:

I have tried to clean up all the references in the VB.NET project that were not being used but above warning messages continue appearing.
Also I have gone into Manage NuGet Packages but I have not seen any duplicate packages in the list.
I don't see the duplicates anywhere (vbproj project file, app.config, etc.). Where can I find those duplicates? Where are the duplicates? How to search for the duplicates?
Finally, I know there is another way to resolve those conflicts (I have not tried yet) and it consists on adding binding redirects for all the assemblies that are conflicted in the app.config file. For example, in case of ClosedXML DLL:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="ClosedXML" publicKeyToken="fd1eb21b62ae805b" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-0.85.0.0" newVersion="0.85.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
Instead of adding manually confliting assemblies in the app.config file, I know it can be done automatically by Visual Studio by adding the property entry below in the vbproj project file:
<AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
as explained here.
Anyway, I would like to resolve those conflicts without binding redirects for all the conflicted assemblies in the app.config file. So Is that possible? If so, how?
Also I have some other questions in mind:
Binding redirects for conflicted assemblies in the app.config file
is a good practice?
Why those conflicts between assemblies happen? I do not understand it at all, so please could you explain me this?
What happens if I not resolve those conflicts and I ignore them (since solution is build successfully without errors)? Is it mandatory or highly recomended to resolve them for any kind of reason that I currently do not know?
I'm getting this error when I add EntityFramework to my project .

I am using EF6 but got this error Assembly 'TBLib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' which has a higher version than referenced assembly 'EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
You have to uninstall related packages and re-install them by using package manager console
I am adding MvcSiteMapProvider in my sample site using Package Manager console like
PM> Install-Package MvcSiteMapProvider.MVC4
but after installation completion facing below Error.
i.e.

Error is like below :

I have changed all references form config files, which are referencing to version 4.0.0.0 to 4.0.0.1, but even after that above error is coming. Please help me.
