Public Property Flags As AssemblyNameFlags

Property Value

AssemblyNameFlags

A value that represents the attributes of the assembly.

Examples

The following example emits a dynamic assembly and saves it to the current directory. When the assembly is created, the Flags property is used to specify that the assembly has a public key.
