TagPrefixAttribute Class
Defines the tag prefix used in a Web page to identify custom controls. This class cannot be inherited.
Assembly: System.Web (in System.Web.dll)
The TagPrefixAttribute class defines an assembly-level attribute needed to specify tag prefix aliases for custom controls. This attribute is used by tools such as Microsoft Visual Studio to automatically generate a Register directive in the ASP.NET page where the custom controls are used.
This directive registers the tag prefix with a namespace. Moreover, it specifies the assembly where the custom control code implementation resides. With this directive in place, you can use custom controls in a Web page declaratively.
