Silverlight project does not update when Ran

Question

I am currently developing VS2010 RC and Silverlight 4 and have run into a small problem. My project, when I ran, showed the version that I built about 4 hours ago. (I built a project using a business template). The project itself will not be updated, which means all forms and controls.

I have done the following:

• Rebooted the computer.
• Reboot Visual Studio
• The deleted xap file in the ClientBin folder on the web page
• Client Generated_Code Folder Removed
• Remote xap file from Client side Debug folder
• I opened the Configuration Manager solution and made sure that both my web projects and client projects were checked.
• Every combination of various projects and solutions has been rebuilt, built and cleaned.
• Deleted and re-added project in MTT.Web properties

Is there a known bug or something else that I can try?

Answer 1

A few things you can try:

1) Clear your cached / temporary internet files in your browser.

2) Make each XAP URL unique to prevent client side caching. One method using the Page class in ASP.NET:

<param name="source" value="<%=ResolveClientUrl("~/ClientBin/YourApp.xap?x=" + (new Random()).Next(1000000)) %>" />

3) Do you use a proxy server? Is there proxy caching? The above method should prevent proxy caching.
