Question

I’ve just encountered a strange mistake in a Silverlight project I’m working on with Visual WebDeveloper Express. When I change the MainPage.xaml file the changes show up in the editor window and the project is compiled without problems. However during Debug Mode the website hasn’t changed.

My goal was to implement a very simple image viewer for my father: One big image with a small progressbar below. It should be possible to set up a few images that are shown one after another in the huge image control. This is what I did.

1. I added two rows to the standard
   grid
2. I added a progressbar to one of the rows
3. I added an image control to the other row

So far everything went fine. Debugging showed an empty website with a small bar at the bottom.

1. I imported a test image and modified
   the source attribute of my image
   control

After some struggles with Visual WebDeveloper the image was accepted and could be seen in the editor’s preview area.

1. I compiled the project and started debugging. There was no image on the website.

I don’t know what’s wrong with my project but the builds seem to have frozen. Just for fun I replaced the image with one giant button. Nothing happened. Compilation was performed without errors but on the website there was no button. After a few other simple tests I was sure: Changes don’t apply anymore.
This is the compiler output, sorry but it’s German :

========== Build: 1 erfolgreich oder aktuell, Fehler bei 0, 0 übersprungen

This is an English version of the last two lines

Build: 1 successful or up to date,
error at 0, 0 skipped

What shall I do ?

Edit:

I just made an interesting discovery:

1. I switched the build mode to release
   and recompiled everything. –No
   changes
2. I closed my browser.
3. I switched the build mode back to
   debug and recompiled everything.
4. When I started debugging Firefox 4
   Beta 7 opened instead of Firefox
   3.6.1. This is strange because 3.6.1 is my standard browser.
5. The changes were applied.
6. I started editing this post using
   Firefox 3.6.1
7. I started debugging again. The
   updated website was shown in FireFox 3.6.1
8. I changed something in MainPage.xaml
   and compiled. As Firefox 3.6.1 was
   still open the website was opened
   with it. The new changes were not
   applied

Obviously Firefox 3.6.1 prevents proper rebuilding. Why ? @ Robaticus maybe you’re right and Firefox does store the site in some kind of cache. However I’m not able to clear it : The button “delete chronic” is disabled because I’m always using private mode.

Edit 2:
Firefox 4 Beta 7 does the job. The changes are applied. Still I would like to know how to use Firefox 3.

Tagging on to ChrisF, you may also want to explicitly clear your chache on your browser. I’ve had that happen before, where the XAP file gets cached for some reason, and never appears to update.
