Unable to change the assembly name

Hello all, I've been trying to change the assembly name and namespace for our project. For some reason I can't do that, because I keep getting the "Could not load file or assembly 'OldAssemblyName' or one of its dependencies. The system cannot find the file specified." Stack Trace:

Why is this? I've looked through the web.config and everywhere in the solution for the old assembly name, but I'm pretty sure I've managed to replace all of them. When I change back to the old name, everything works again. Any suggestions?

Hi, you have one or more custom property types in your old assembly, that have self registered, and used by one or more page types. Go to Admin mode, select the Page Type tab, click Edit Custom Property Types. If you're using 4.61, the headers in that table is messed up, but the Class name column is the assembly name, and look for lines with your old one. Click the ones that point to the old assembly, and change the assembly name to the new one. If you have moved things around, you might have to change the namespace name too. There is a chance that you have duplicates in the list. Try to identify these before you start renaming things, and delete the ones that point to the new assembly. When you compiled your project with a new assembly name, it auto registered these property types during startup - hence the duplicates. The new ones are not in use yet - so you can simply delete them, and rename the ones that point to the old assembly. That should fix it. /Steve
