' Container for any general design-time metadata to initialize.
' Designers look for a type in the design-time assembly that

' this class and access its AttributeTable property automatically.
Friend Class Metadata
Implements IProvideAttributeTable
' Accessed by the designer to register any design-time metadata.
Public ReadOnly Property AttributeTable() As AttributeTable _
Implements IProvideAttributeTable.AttributeTable
Get
Dim builder As New AttributeTableBuilder()
builder.AddCustomAttributes( _
GetType(ButtonWithDesignTime), _
New ToolboxBrowsableAttribute(True))
Return builder.CreateTable()
End Get
End Property
End Class
// Container for any general design-time metadata to initialize.
// Designers look for a type in the design-time assembly that
// implements IProvideAttributeTable. If found, designers instantiate

internal class Metadata : IProvideAttributeTable

public AttributeTable AttributeTable

{
AttributeTableBuilder builder = new AttributeTableBuilder();
