What will happen if the following code is compiled in .NET 4 or above (Assume required namespaces are included)?

public class var { }

public class main

{

    public static void main(string[] args)

    {

        var testVar = new var();

    }

}

This code will not compile, as var is a reserved keyword, so it can not be used as a class name.

This code will compile, as var is merely a contextual keyword and it is used to provide a specific meaning in the code, so it will cause no problems.

This code will not compile, as a new object cannot be created like var testVar = new var();

None of these.

Answer
