Every time I open solution in Visual Studio 2015 I get following message:
Here are last entries from ActivityLog.xml:
<entry>

I followed suggestions found in a similar question but with no success.
Unfortunately re-installing NuGet via Extensions and Updates doesn't solve the issue.

I had this error on .netcore 3.1 only:
The 'windows forms remote designer hosting package' package did not load correctly
Resolved with the help of all of the answers here.
Remove the entire contents of the directories:

Deleting this folder did the trick for me.

This one helps with VS 2017: https://developercommunity.visualstudio.com/content/problem/160124/failed-to-load-package-monoandroiddesignerpackage.html
1) Start VS
2) File->New->Project->Xamarin app (either iOS or Android)
3) Now click the Toolbox
4) Close VS

Run the following command prompt help me solve the problem on VS 2017 Community. I never tried on other VS version though. Let me know if it works in other version:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\devenv.exe" /resetskippkgs

What did the trick for me was removing "Microsoft .NET Core 1.0.1 VS 2015 Tooling Preview 2"

If @batressc solution doesn't work, you have to delete the .VS
folder in the solution folder also.
So:
C:\Users\<username>\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
[Solution Folder]\.vs
