Copy.com can recover files, not from the web, but from the Windows and Mac UI (via Can I recover deleted files? : Copy)

Posted by jpluimers on 2014/01/09

Didn’t know this was possible in copy.com. In DropBox this is a breeze in the Web interface (full history of all files is accessible) but I always try to be better safe than sorry:

The Windows and Mac OS X user interfaces of the Copy.com tool can undelete files though: Can I recover deleted files? : Copy.

Good to know, as eventually I’m probably going to need this.

When two types are not the same: Assembly Load Contexts Subtleties (via: All Your Base Are Belong To Us)

Posted by jpluimers on 2014/01/09

Reading c# – Type.IsSubclassOf does not behave as expected – Stack Overflow, I found this very interesting link via Assembly Load Contexts Subtleties at Sasha Goldshtein’s blog (I love the name of the blog: All Your Base Are Belong To Us).

He explains the reasons for the error message

System.InvalidCastException: Unable to cast object of type ‘Plugin.MyPlugin’ to type ‘Plugin.MyPlugin’.

Actually his blog entry is an abstract of a 200+ page thesis on  that is also recommended reading: Flexible Dynamic Linkin for .NET (by Anders Aaltonen, Alex Buckley and Susan Eisenbach).
