<p><em>Inconsistent accesibility: property type 'WindowsFormApplication1.ContactFiles.Contact' is less accessible than property 'WindowsFormApplication1.ContactForm.ContactData'</em></p>

<pre><code>public ContactFiles.Contact ContactData
    {
        get
        {
            return m_contact;
        }
        set
        {
            if (value != null)
                m_contact = value;
        }
    }
</code></pre>
