SharePoint Short #9
When using SharePoint Designer, especially in a development environment where content and assemblies can frequently change, SPD can start to behave erratically, sometimes loading content that has been removed from the web site, or using an older version of an assembly. This is due to how SPD caches content, which thankfully, is easy enough to clear.
First, close SPD and then remove all files from the following folder:
%APPDATA%\Microsoft\Web Server Extensions\Cache
This contains things like page caches.
Then, do the same for this folder:
This contains cached items such as assemblies used and lots of other xml configuration files.
Restart SPD and all should be good in the world 🙂
