"Unable to start debugging" (Silverlight Trial VS2013)

Hi Nathaniel,

Thanks for evaluating our controls.  I'm sorry you are having problems.  From what you show in the screenshot, it appears that it's something that is wrong with your Silverlight SDK in general and nothing specifically related to our products.

I did some searching on the web and found these posts, which seem like they might be similar to your scenario.  Can you try out some of the steps they mention there as answers and see if it helps?  Please let us know.

TL;DR Solved - Mostly a VS issue.

Thanks for your quick reply, your links were informative.  However after following them I failed to see any improvement.

So what I did next was to try build a normal Silverlight application, and I got the same error.  However, this time in the 'debug' section it let me pick my browser.  Unsurprisingly it was defaulting to my parallels 'shared' browser (basically a virtualisation tool that lets me open browser window from my windows vm in my mac host).  I selected one of my VM's browsers and it worked perfectly.

So I go back to your application and I have no option to select a browser :(

Solution?

Create a html file, click 'Browse With' delete the 'shared' browser and select IE.  

Great now it no longer complains, and launches fine.  However immediately there is an error, something about a corrupt manifest?  

Solution, ensure the start-up object is set in project settings.

*Phew*

I'm glad you got it working.  Normally you just install and can instantly compile/run without any changes.  I guess the configuration your system has makes things a bit more complex.
