.NET (Core and Framework)

1. Why are we not allowed to provide parameterless constructors
   for value types? (I find it a large limitation, since I sometimes
   need defaults/initialization other than the process provides)/li>
   
2. Why is the ValueType derived from Object?
3. Since the derivation of ValueType from Object, makes it a class why boxing?
4. Why is "ValueTypeArray" not provided instead of just Array for everything?
5. Why is there no common base ValueType for numerics/numbers?

public class TestClass
{
    private ValueType m_valueMax;

 public TestClass(ValueType value)
 {
        m_valueMax = value;
 }

    public ValueType Value 
    {
        get
        {
            return m_valueMax;
        }
    }
}

public class TestClass
{
    private object m_valueMax;

 public TestClass(object value)
 {
        m_valueMax = value;
 }

    public object Value 
    {
        get
        {
            return m_valueMax;
        }
    }
}

if (value == null)
    throw new ArgumentNullException("value");
