Entity Framework - Unable to load the specified metadata resource

Question

I realise that this has been asked a number of times but I just can\'t seem to get the bottom of my issue. I\'m getting the following error stack:

Answer 1

I hit this issue and it has bit me many, many, many times and I always forget how I fix it.

All I had to do is set the default.aspx as the start page.

Obviously this won't help everyone but in my case I have gone down the road of checking my config, connection string...

Hope this help someone, or at least the next time I google it I will find my fix. :)
