>From "cold start" of MonoDevelop (2.8.4.1) to failing to run the app once these are the errors in my Message log.

Also my breakpoints are throwing erros in MonoDevelop now (it doesn't crash).. to be clean I'll start a new thread for that issue.

(these two from running the app)

Hi again,

Do any errors show up in the Message Log (accessible via the View / Pads menu), something like "Exception while loading assemblies"?

Please Clean and rebuild your project first.

If you're using MonoDevelop, please try using the recently released MonoDevelop 2.8.4.1.

Thanks,
