I know that it is possible to load xap modules dynamically using Prism or MEF framework. However, I\'d like not to use those frameworks; instead load my xap files manually.
this XAP Cache phenomena is often due to the visual studio embedded web server (ASP.NET Development Server).
Just stop the occurence of this server and the cache will be cleared.
Start again your project and the latest build of your xap is called.
