# Test environment (full version information)
Visual Studio Enterprise 14.0.25425.01 Update 3
Xamarin.VisualStudio_18.104.22.1685.msi (beta channel and standalone)
I suspect this might be caused by one of the common issues Visual Studio can run into with updating extensions.
In particular, I suspect clearing the ComponentModelCache folder might help. See step 3 on the following guide:
And in case step 3 doesn't solve the issue, please try running through the other steps on that guide briefly too just to be thorough, and report back the results. Thanks in advance!
That solved the issue! Thanks. I also downloaded this extension, that was mentioned, to resolve it in the future: https://visualstudiogallery.msdn.microsoft.com/22b94661-70c7-4a93-9ca3-8b6dd45f47cd.
It was an error with the Visual Studio MEF cache getting corrupted after switching to the Beta channel. Clearing cache solved issue.
Excellent. Glad that worked, and thanks for the verification!
I've put together a build on top of current stable (22.214.171.1245) that should fix this issue: http://xvs.xamarin.com/patcheddrops/Xamarin.VisualStudio_126.96.36.1998.msi
It will also be included in all future releases.
Please do reopen if you see this happen again in the future.
Thanks for reporting the issue!
I installed the patch after I was getting this error and it did not stop it from happening. I deleted the component cache and then the solutions loads droids projects OK. Then I close and reopen VS and it won't load Android anymore with the same error as in the description in the ActivityLog
@John the convention is that this bug would only be reopened by the _original reporter_ at this stage in the bug history because Comment 3 verified that the proposed fix worked for the original reporter.
It sounds like you might instead be hitting the secondary piece of Bug 44300 which involves the Test Recorder preview features.
In fact, since the error message in Comment 0 matches Bug 44300, I'll also mark this as a duplicate of that bug for bookkeeping. Thanks!
*** This bug has been marked as a duplicate of bug 44300 ***
For the record, I still get this error all the time. I just constantly clear the component cache to fix it.
I pretty much use this extension a few times a week to get around this issue: https://visualstudiogallery.msdn.microsoft.com/22b94661-70c7-4a93-9ca3-8b6dd45f47cd.
Ah perfect. It sounds like it's definitely appropriate that this be marked as a duplicate of Bug 44300 then. That bug describes how the problem kept coming back for the users on that bug until they installed the new build from Comment 5 and uninstalled Test Recorder (if installed).
In any case, thanks for the additional verification on the duplication status!
