Remarks

Workspace services which implement IDisposable are considered ownable, in which case the owner is responsible for disposing of owned instances when they are no longer in use. When IWorkspaceService or IWorkspaceServiceFactory instances are provided directly to the HostWorkspaceServices, the owner of the instances is the type or container (e.g. a MEF export provider) which created the instances. For the specific case of ownable workspace services created by a factory (i.e. instances returned by CreateService(HostWorkspaceServices)), the Workspace is considered the owner of the resulting instance and is expected to be disposed during the call to Dispose().

Summary of lifetime rules

IWorkspaceService instance constructed externally (e.g. MEF): Owned by the external source, and will not be automatically disposed when Workspace is disposed.
IWorkspaceServiceFactory instance constructed externally (e.g. MEF): Owned by the external source, and will not be automatically disposed when Workspace is disposed.
IWorkspaceService instance constructed by IWorkspaceServiceFactory within the context of HostWorkspaceServices: Owned by Workspace, and will be automatically disposed when Workspace is disposed.

Constructors

HostWorkspaceServices()

Properties

HostServices	The host services this workspace services originated from.
PersistentStorage	Obsolete. Obsolete. Roslyn no longer supports a mechanism to perform arbitrary persistence of data. If such functionality is needed, consumers are responsible for providing it themselves with whatever semantics are needed.
SupportedLanguages	A list of language names for supported language services.
TemporaryStorage	Obsolete. Obsolete. Roslyn no longer supports a mechanism to store arbitrary data in-memory. If such functionality is needed, consumers are responsible for providing it themselves with whatever semantics are needed.
Workspace	The workspace corresponding to this workspace services instantiation

Methods

Dispose()
FindLanguageServices<TLanguageService>(HostWorkspaceServices+MetadataFilter)	Finds all language services of the corresponding type across all supported languages that match the filter criteria.
GetLanguageServices(String)	Gets the HostLanguageServices for the language name.
GetRequiredService<TWorkspaceService>()	Gets a workspace specific service provided by the host identified by the service type. If the host does not provide the service, this method throws InvalidOperationException.
GetService<TWorkspaceService>()	Gets a workspace specific service provided by the host identified by the service type. If the host does not provide the service, this method returns null.
IsSupported(String)	Returns true if the language is supported.
