Exception Details: System.InvalidOperationException: Search:AppKey cannot be empty. Make sure you set it in the configuration file.

and what difference between AppID and AppKey?

Do a search for AppKey in this tutorial - the code in this sample is throwing the exception because you haven't set it in the Web.config file. See <add key="Search:AppKey" value="[yourkeyvaluehere]" /> in the tutorial.

@raj2511984 - Thanks for the feedback and I'm glad you enjoyed it.

[FacebookAuthorize]

public ActionResult Create(FacebookContext context)

{

return View();

}

[HttpPost]

[FacebookAuthorize]

[ValidateAntiForgeryToken]

public ActionResult Create(FacebookContext context, Dummy dummyFromForm)

{

}

The first method is never called - I think it is because of the Auth-attribute.

Can you provide a solution/sample?

The first method is a HTTP GET, the 2nd a POST. Fiddler is your friend here.

Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

I believe I have followed all the instructions so far but sadly this just won't work :( The only thing I did differently was give it a different project name.

Thanks in advance.

I got the same error. What I did is put in a https url in the second canvas app textbox. it worked then but had an ssl error. So the question is now with the new change on facebook How do we develop and test locally??

The next step was to make sure the browser recognized my SSL certificate as valid and bada-boom bada-bim forget about it... it was all good once again!

Thanks for the feedback.

FB now requires you to use SSL. From the project properties, select True for SSL, then use the SSL URL. I've updated the tutorial and the changes should show up in a couple days.

I created a Facebook app using the template without making any changes. I then published it to Azure. Here is the URL: ipadtest.azurewebsites.net/

The application works fine if you go there with IE, Chrome, the Android FB app or Safari on an iOS device. But if you try to go there from the Facebook application on iOS you get the big broken thumb.

Any ideas?

TIA

I don't understand your answer. I want to show the form on GET, save values on POST. But when I use FacebookAuthorizeAttribute, every time a POST is executed (because of oauth redirection).

I hope you guys continue with these kind of tutorials.

I would like to suggest MVC tutorials with following subjects;

Google translator, Google Maps, Google Drive, Multilingual architecture design, Twitter, LinkedIn etc.
