Variables declared in partial class not visible to second partial class declaration?

So I have two different source files:

file1.cs:

namespace namespace1 {
    public partial class Class1 {
        public partial class NestedClass {

             public int myInt{ get; set; }

        }
    }    
}

file2.cs:

namespace namespace1.Class1 {
    public partial class NestedClass {

         void doSomething() {
             Console.WriteLine(this.myInt); // class does not contain definition for myInt
         }
    } 
}

The Problem:

I am trying to access a member variable declared in the first partial class in the second. No variables I declare can be viewed from the other file.

My Attempts at a Solution:

I found this post, but it did not seem to fix my issue. I declared several test variables in each of the partial class files and nothing was visible to the other file. I tried both public and private variables, with and without setters, since the problem in that situation involved a missing setter. I thought maybe my classes were named incorrectly, so I triple checked my namespaces as well as class names and that they were both declared partial. Finaly, I have tried restarting Visual Studio as well, to no avail.

Any help would be greatly appreciated!
