-When you have finished using an application domain, unload it using the <xref:System.AppDomain.Unload%2A?displayProperty=nameWithType> method. The **Unload** method gracefully shuts down the specified application domain. During the unloading process, no new threads can access the application domain, and all application domain-specific data structures are freed.
+When you have finished using an application domain, unload it using the <xref:System.AppDomain.Unload%2A?displayProperty=nameWithType> method. The **Unload** method gracefully shuts down the specified application domain. During the unloading process, no new threads can access the application domain, and all application domain–specific data structures are freed.
 
  Assemblies loaded into the application domain are removed and are no longer available. If an assembly in the application domain is domain-neutral, data for the assembly remains in memory until the entire process is shut down. There is no mechanism to unload a domain-neutral assembly other than shutting down the entire process. There are situations where the request to unload an application domain does not work and results in a <xref:System.CannotUnloadAppDomainException>.
