Since moving to Umbraco 10 (and now 11), I often get this strange error when debugging locally. I've searched in the forum and it seems like no one has reported the exact same error message.
The solution is always a good old fashioned restart of my PC, then the error goes away.
But I would really like to know why this is occuring. Has anyone perhaps more info regarding this?

I have been getting the same error locally every now and then. The only solution (mind you, not a proper solution) has been to:
Clean&Rebuild (works 10% of the time)
Close and restart Visual Studio (works about 20% of the time)
or restart my computer (usually solves it)
But the problem still persists and comes back after maybe 1-2 days. If anybody else knows why this is happening, or how to prevent/solve it any help would be appreciated!
I've just run afoul of this error as well. I tried cleaning & rebuilding, restarting VS, and restarting my pc, but no luck. It seemingly came out of nowhere.
Bumping this post hoping someone has any insight on this.
I'm marking this as the solution since this always works for me.
Would however still be great if someone can explain this error more in depth. I always get it when making configuration changes in appsettings, changes in startup.cs or nuget updates.

I cleaned, but then deleted the bin and obj folders in my Umbraco project, and that seemed to do the trick.

Do you have your solution broken up into separate code and website projects? I did - had this and a different issue.
Seems to have gone away now I've just got a single project.
Yes, I have. Can't switch to single project though. We're a large organization with many dependencies.
Good point though!
is working on a reply...
