EF6 throws error, invoking exe from different machine's shared folder

Developed an exe using .Net framework 4.0, EF 6.0. It works fine in machines where .Net framework 4.0, 4.5 full version installed.

But when I invoke the same exe from different machine's shared folder, it throws error. it is because of entityframework tag in the config.

Server Machine has shared folder with .Net 4.5 installed. SharedFolder contains the exe developed using .Net 4.0.

Error

'System.Data.Entity.Internal.AppConfig' Type initializer for threw an exception

one more solution,

after removing below tag, it worked. 

  <entityFramework>
    <!--<defaultConnectionFactory type="System.Data.Entity.CrossCutting.SqlConnectionFactory, EntityFramework"/>--> 

    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer"/>
    </providers>
  </entityFramework>

guys, is this tag mandatory???

From my machine (.Net 4.0 installed), if I execute exe from different machine's (.Net 4.5.1 installed) shared folder, it throws error when exe's config has above tag. works if I remove the above tag.

If we execute the same exe in local machine (.Net 4.0), it works with or without above tag.

It sounds like the Microsoft .NET Framework 4 Client Profile is installed on the problem system. Installing the full framework on the client PC should resolve the issue.

The Microsoft .NET Framework 4 (full) version can be found here:
