After installing the RTM version of VS2012 last week and upgrading my project, I noticed that my web site was broken. The real culprit seemed to be that Microsoft changed how bundling works (the process of combining and minifying resources like js script and css files) between the RC version and the RTM version. For an excellent background on what this feature can do for you, see this tutorial
It turns out my real problem was with Kendo. They don't provide non-minified files in the trial version, so the new bundling mechanism wasn't including the minified assets, which meant the Kendo minified assets were getting stripped out when I was trying to run under debug. (Reference here
). I was able to use the work-around offered on this thread, and things started working again.
However, there are a few wrinkles when using the bundling code, so I thought I'd capture my experiences here. For example:
It seems that there is quite a bit of friction in the current version of the bundling framework. Fortunately, it resides in the Optimization assembly which can be upgraded independently of the entire MVC framework. I hope Microsoft releases an update very soon to overcome these obstacles. I have every reason to believe that they will since I'm seeing the author of this assembly
