C # /. NET Project - Am I setting things right?

Question

The 1st solution is located : \ Common \ Controls \ Controls.sln
  and its project : \ Common \ Controls \ Common.Controls \ Common.Controls.csproj
  Description: This is the library that contains this class:

public abstract class OurUserControl : UserControl
{
    // Variables and other getters/setters common to our UserControls
}

The 2nd solution is located : \ AControl \ AControl.sln
  and its project : \ AControl \ AControl \ AControl.csproj
  Description: from many forms / classes it will contain this class:

using Common.Controls;

namespace AControl
{
    public partial class AControl : OurUserControl
    {
        // The implementation
    }
}
