How to get reference to 'Roslyn' Workspace

问题:

I have a VS Package project from which I need to access Roslyn or Microsoft.CodeAnalysis' Workspace OR Solution object from the loaded IVsSolution.

I need to know how I could achieve that ?

I found this stackoverflow discussion here which suggests to use PrimaryWorkspace static property of Workspace class which I can't find in Microsoft.CodeAnalysis.Workspace

EDIT: I found out that Microsoft.CodeAnalysis does not have this yet but I downloaded the older release of Roslyn from Nuget.org which has this. But now PrimaryWorkspace Property is giving me NULL :( I am using Isolated Shell.

回答1:

The VisualStudioWorkspace is exported through MEF. If you are already using MEF in you package, you can just [Import] it.

If not, you can QueryService() for the SComponentModel service and then get the VisualStudioWorkspace from that.

回答2:

Within the Initialize() function of your VSPackage, you can use the following:

var componentModel = (IComponentModel)Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(SComponentModel));
var workspace = componentModel.GetService<Microsoft.VisualStudio.LanguageServices.VisualStudioWorkspace>();

I believe you'll also need to add an additional reference to: Microsoft.VisualStudio.LanguageServices.dll

As noted by @Vizu, you can now add this via NuGet:

Install-Package Microsoft.VisualStudio.LanguageServices
