• When you create workflows for SharePoint lists or libraries by using Workflow Designer, SharePoint Designer makes Web service calls to SharePoint to determine the latest versions of the important SharePoint files. SharePoint Designer then stores a cached copy of these files locally on the computer where it's installed. This location, called the ProxyAssemblyCache, is stored on the SharePoint Designer machine at C:\Documents and Settings\<username>\Application Data\Microsoft\SharePoint Designer\ProxyAssemblyCache. While this is a temporary cache, SharePoint Designer always looks for files inside this folder when creating workflows. If for some reason (such as a version upgrade or solution deployment) the server version of the files changes, SharePoint Designer might not be aware of it and would still use the cached version, which might cause errors and problems in SharePoint Designer while creating workflows. To ensure that SharePoint Designer requests the latest version of files, you can delete the contents of the ProxyAssemblyCache ...
