EnvDTE.ActiveDocument in VSIX Project

James Bendler 1

I'm writing a VSIX project in Visual Studio 2022 Preview.

If I try to execute this code, it fails with
System.MissingMethodException: 'Method not found: 'EnvDTE.Document EnvDTE._DTE.get_ActiveDocument()'.'

Code:

ThreadHelper.ThrowIfNotOnUIThread();
DTE dte = (DTE)MyPackage.GetGlobalService(typeof(DTE));
string name = dte.ActiveDocument.Name;

Remove all references to envdte and shell interop.

Open NuGet and add the following packages: Microsoft.VisualStudio.SDK and Microsoft.VSSDK.BuildTools

Double click source.extension.vsixmanifest inside your VSIX project, select Metadata tab

Once there increase the version number of your extension

Build the project

Find yourapp.vsix inside bin folder and install it

Troubleshooting when uninstalling:
If you remove your VSIX using Extensions menu in VS, you'll need to close VS in order to let uninstall to happen.
Sometimes it doesn't uninstall completely, so make sure to open the log after the uninstall procedure ends.
In the log, get the path where the extension was installed. Open it in the file explorer and remove the folder entirely. Now the uninstall is complete and you can install new version of the extension.
