The extension doesn't work in VS2017 if some features aren't installed

The problem still happens with VS2017 15.9.9 :(

The fix seems to be straightforward - it is enough to catch System.Runtime.InteropServices.COMException in GetDTE() (in \VSFileNav\VSNav\Code\Gathering\EventManager.cs):

try
{
    this.webProjectEvents = dte.Events.GetObject("WebSiteItemsEvents") as ProjectItemsEvents;
}
catch (System.Runtime.InteropServices.COMException)
{
}

I tested it in my VS2017 without installed ASP.NET, and the custom-built addon works fine :)
Here is the binary with hotfix - VSNav-HotFix.vsix.zip
Just a reminder: the command is Edit.QuickFindFile with global shortcut Ctrl + Alt + F.

PS: Since this addon seems to be abandoned, it makes sense to switch to native navigation with Ctrl+, or Ctrl+Shift+T(see also https://stackoverflow.com/a/44164379/536172).

I've taken a look into the code and found the fragment in \VSFileNav\VSNav\Code\Gathering\EventManager.cs:

this.cSharpProjectEvents = dte.Events.GetObject("CSharpProjectItemsEvents") as ProjectItemsEvents;
this.vbProjectEvents = dte.Events.GetObject("VBProjectItemsEvents") as ProjectItemsEvents;
this.webProjectEvents = dte.Events.GetObject("WebSiteItemsEvents") as ProjectItemsEvents;

My Visual Studio Community 2017 (15.5.6) doesn't have the feature for Web-development installed (I've installed only limited set of features), so I guess the problem may be related to this...

I've accidentally ran into the missing feature error when trying to open some specific project:

Here is the full list of installed products:

It looks like a problem in VS, which fires a critical error when requested features isn't installed... but I could have overlooked something.

I installed the ASP.Net and Web Development Package and that fixed the problem for me.

Installing extra features is a good workaround. Though with a small free space (on some SSDs) it may present a challenge...
And I'd expect the issue to be fixed other way (installing unusable features of VS2017 seems to be an overkill).

Hello. I also experienced this issue. I have 110Gb ssd with a little space left, so, yep, it's challenging.
