Silverlight Project Not Updating When Ran

Question

I'm currently developing with VS2010 RC and Silverlight 4 and ran into small problem. My project when ran, would show a version I had built about 4 hours ago. (I built the project using the Business Template) The project itself will not update, meaning all the forms, and controls.

I did the following:

• Restarted my computer
• Restarted Visual Studio
• Deleted the xap file in the ClientBin folder on the web side
• Deleted the Generated_Code folder on the client side
• Deleted the xap file from the Debug folder on the client side
• Opened the Solution's Configuration Manager and ensuring both my web and client projects are checked.
• Rebuilt, built, and cleaned every combination of the different projects and solution
• Deleted and re-added the project in the MTT.Web properties

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

Answer 1

A few of things you might try:

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

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

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

3) Are you using a proxy server? Is there caching on the proxy server? The above method should prevent proxy server caching.
