How do I pass an object to another program?

I am having trouble passing a serialized object from one program to another.

The two programs are compiled in the same solution and are running on the same computer. The object source is in a shared folder in the same solution.
Program A serializes the object and writes it to a named pipe.
Program B reads the serialized object from the named pipe and attempts to assign the de-serialized object to the same object type.

I receive the following error:

[A]FileFind.FileFind.Shared.cs.CMUtilitySchedule cannot be cast to [B]FileFind.FileFind.Shared.cs.CMUtilitySchedule.
Type A originates from 'FileFind, Version=5.0.0.6, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'I:\RogerFolders\Documents\Visual Studio 2013\Projects\Test\FileFind\FileFind6000\FileFind\FileFind\bin\Debug\FileFind.exe'.
Type B originates from 'FileFindCM, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' in the context 'Default' at location 'I:\RogerFolders\Documents\Visual Studio 2013\Projects\Test\FileFind\FileFind6000\FileFind\FileFind\bin\Debug\FileFindCM.exe'.

How can I pass objects to another running program via a pipe?

What I have tried:

I am thinking of creating a function in the object that will create a CVS or XML stream. I would then serialize the resulting stream and send it to the other program. However, that would be a non-intuitive maintenance nightmare.

Other suggestions would be welcome.

See this case:

C#

// project for A.exe
namspace A {
  public class FileFind {
    // ...
  }

  class A {
    public static void Main(string[] args) {
      // using FileFind...
    }
  }
}

// project for B.exe
namspace B {
  public class FileFind {
    // ...
  }

  class B {
    public static void Main(string[] args) {
      // using FileFind...
    }
  }
}

In this case there are two different types even FileFind has the exact same code in project A and B...
To resolve it you have to move FileFind to a third project and reference it both from A and B

C#

// project for F.dll
namspace F {
  public class FileFind {
    // ...
  }
}

// project for A.exe
using F;

namspace A {
  class A {
    public static void Main(string[] args) {
      // using F.FileFind...
    }
  }
}

// project for B.exe
using F;
namspace B {
  class B {
    public static void Main(string[] args) {
      // using F.FileFind...
    }
  }
}
