Workspace Class

Definition

Namespace:

Microsoft.CodeAnalysis

Assembly:

Microsoft.CodeAnalysis.Workspaces.dll

Package:

Microsoft.CodeAnalysis.Workspaces.Common v4.9.2

Source:

Workspace.cs

A workspace provides access to a active set of source code projects and documents and their associated syntax trees, compilations and semantic models. A workspace has a current solution that is an immutable snapshot of the projects and documents. This property may change over time as the workspace is updated either from live interactions in the environment or via call to the workspace's TryApplyChanges(Solution) method.

Constructs a new workspace instance.

Properties

CanOpenDocuments	True if this workspace supports manually opening and closing documents.
CurrentSolution	The current solution. The solution is an immutable model of the current set of projects and source documents. It provides access to source text, syntax trees and semantics. This property may change as the workspace reacts to changes in the environment or after TryApplyChanges(Solution) is called.
Kind	The kind of the workspace. This is generally Host if originating from the host environment, but may be any other name used for a specific kind of workspace.
Options	Obsolete. Gets or sets the set of all global options and Options. Setter also force updates the CurrentSolution to have the updated Options.
PartialSemanticsEnabled	Override this property if the workspace supports partial semantics for documents.
Services	Services provider by the host for implementing workspace features.
