Deletes a part with a given URI from the package.
Assembly: WindowsBase (in WindowsBase.dll)
partUri must be a relative URI that consists of an absolute path which starts with a forward slash ("/") character. The absolute path is relative to the package root and is formed according to the RFC 3986 Uniform Resource Identifier (URI) Generic Syntax specification. "/page1.xaml" and "/images/picture4.jpg" are examples of valid part URIs.
No exception is raised if a part with the specified partUri is not in the package. (You can use the PartExists method to determine whether a part with a specified partUri is in the package.)

internally calls the derived class's DeletePartCore method to actually delete the part based on the physical format implemented in the derived class.
