Unable to use VisualStudio.Extensibility from existing VSSDK extensions

Christopher Christou commented 2 months ago

I was following the documentation for Use VisualStudio.Extensibility from existing VSSDK extensions to access the new Extensibility model from an existing VS SDK based extension. When I try to get the VisualStudioExtensibility service (my sample code), I get an exception "The VisualStudioExtensibility service is unavailable."

I tried this using Visual Studio version 17.9.5, and with version 17.9.2092 of NuGet packages Microsoft.VisualStudio.Extensibility, Microsoft.VisualStudio.Extensibility.Sdk, and Microsoft.VisualStudio.Extensibility.Build

Hi @awschristou, would you be able to enable all exceptions in the debugger (disabling Just My Code) before that GetService line and see what inner exception is thrown?

Just as an FYI, using VisualStudioExtensibility in that way will provide very limited API support since it wouldn't be running in the context of an extension.

We recommend the earlier approach listed https://learn.microsoft.com/en-us/visualstudio/extensibility/visualstudio.extensibility/get-started/in-proc-extensions?view=vs-2022#requiresinprocesshosting-property starting with a class inheriting from Extension

Thanks

Hi @BertanAygun , here is the exception message:

Could not load file or assembly 'Microsoft.VisualStudio.Extensibility.EditorHostService, Version=17.9.145.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

In case it helps, here is some additional information from the Exception:

Just as an FYI, using VisualStudioExtensibility in that way will provide very limited API support since it wouldn't be running in the context of an extension.

Makes sense -- For additional context, I was exploring the use of the VisualStudioExtensibility from code based in VS SDK as a way to start porting portions of an existing extension codebase without performing larger refactors towards using the newer extensibility contribution points just yet.

That exception helps, thanks. Unfortunately, this is an issue we noticed recently as well and should be fixed in 17.11 Preview 1 when released.

Until then a possible workaround would be to deploy assembly in question with your extension.

You can get a copy of the assembly from, it is netstandard 2.0 so should be fine to load in devenv:

"\Common7\ServiceHub\Hosts\ServiceHub.Host.Extensibility.amd64\Microsoft.VisualStudio.Extensibility.EditorHostService.dll"
