System.TypeInitializationException thrown

I am making an application in ASP.NET MVC 5 C #. I am getting an exception while trying to access the connection string element from the web.config file.

An exception of type "System.TypeInitializationException" occurred in WebPortalClient.dll but was not handled in user code

Web.Config:

<?xml version="1.0" encoding="utf-8"?>

The solution I found about this:

This exception means that the following line doesn't work (check the fitting line in the code):

public static string ConString = 
    ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;


Make sure there is no exception here!

Whenever a TypeInitializationException is thrown, check all the initialization logic of the type you are accessing the first time in the statement in which the exception is thrown.

If it doesn't work you can use this post
