I am trying to fix warning

> 
> Warning CS0436: The type 'Class1' in '...\SharedProject1\SharedProject1\Class1.cs' conflicts with the imported type 'Class1' in 'ClassLibrary1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Using the type defined in '...\SharedProject1\SharedProject1\Class1.cs'. WpfApplication1 ...\SharedProject1\WpfApplication1\MainWindow.xaml.cs

Repro:

* create solution with 3 projects:

**SharedProject1** (add new class to it)

```
namespace SharedProject1
{
    public class Class1() { }
}

```

**ClassLibrary1**

```
namespace ClassLibrary1
{
    public class Class1 { }
}

```

**WpfApplication1** (add this to `MainWindow` constructor)

```
public MainWindow()
{
    InitializeComponent();
    var a = new SharedProject1.Class1();
    var b = new ClassLibrary1.Class1();
}

```

* reference `SharedProject1` in both `ClassLibrary1` and `WpfApplication1`;
* build, you will get a warning.

Question: how to fix the warning?
