## Description

(I have not been able to reproduce this, so relying on customer reported info)

From reporting customer:

"I recently went through updating my Xamarin tools, both from doing updated within VS and by running the full downloaded Xamarin installer. Now when I start VS and then load a project, I get this popup [1]. Note that I wasn't loading a solution that contained Xamarin projects, I was loading another C# project. This also happens if I open a solution or project directly from Windows Explorer (which then launches VS to open that project).

If I look in the log references, I see this:"

## Notes

Since this seemed similar to error message received when the XamarinShellPackage can't be loaded, I had them try deleting the ComponentModelCache which was a workaround to resolve that issue (bug #40781) but that did not help. The reporting customer added the following findings:

"Clearing the component cache had no effect (the error still happens). However, I have noticed that it only happens when I try and load non-Xamarin projects now. And it only happens once per run of VS. So, if I start VS and open a Xamarin project then there is no error. If I then close that project and open a non-Xamarin project, then I get the error once. I can then flip between all types of projects without seeing that error again, until I start a new instance of VS.

I have not gone further and verified that all aspects of Xamarin projects still function though once this error happens as I am not clear on which Xamarin component is failing and what I would be looking for (i.e. what component may stop working after the error)."

Hi Jon, thanks for filing.

Can you find out what kind of project this was? I'll do some poking around to see if I can reproduce. I've never seen this with basic WPF or Console projects before.

Also, for future reference, the Inspector extension has its own log files. See https://developer.xamarin.com/guides/cross-platform/inspector/install/#Reporting_Bugs .

Comment 5 David Jade 2016-12-09 21:10:43 UTC
No, it is not a ASP.NET project. It is a solution that has a Windows Service, a WPF app, a bunch of shared libraries, a shared code project, and a Wix setup project.

I am seeing additional behavior today. VS is behaving that if I open another project first (even a non-Xamarin project), then close the solution and then opened the offending solution, the problem does not happen. In other words, opening another solution first somehow prevents the problem until the next time I restarted VS. However not all solutions that I open first prevent the issue, only some. It did not seem to matter if it contained Xamarin projects or not.

Now after opening and closing VS and several solutions, I think I may have uncovered another main contributing factor. The solution that triggers this issue has multiple debug start up targets set for the solution. If I change the setting to only have one start up target, then opening this solution does not seem to trigger to issue. if I change it back, restart VS, then open it again it will then trigger the issue.

As a test I created a new blank solution, add a few random console projects I had lying around, set this new solution to have multiple debug start up targets, saved it, closed VS, restart VS, and the loaded the solution. The issue appears 100% of the time for this new solution with multiple debug targets. If I change this new solution to have just one debug start up target the problem goes away.

It is still true however then first opening another solution will sometimes prevent the issue when opening these solutions that have multiple start up targets set for debugging.
Comment 6 Sandy Armstrong [MSFT] 2016-12-09 21:44:27 UTC
Thanks for digging in. Yes, the Inspector doesn't have very good support for multiple start-up projects (yet).

The error you're seeing happens when we examine (what we think is) the startup project to see if it's a valid inspection target. I'll make that safer so you don't run into any more errors.

We can look at providing better support for multiple start-up projects in the future.
Comment 7 Sandy Armstrong [MSFT] 2017-01-14 17:42:05 UTC
Error fixed in upcoming 1.1 release. You will no longer see the popup.

We are tracking proper multiple start-up project support separately.
