Can DotNetOpenAuth be used within a Silverlight application - silverlight

I have used DotNetOpenAuth previously in an ASP.net website and it works fine. But now I wanted to create a Silverlight app. Unfortunately I can't reference DotNetOpenAuth.dll, since this is not compiled against the Silverlight CLR. Is there a solution to use open authentication from Silverlight?

DotNetOpenAuth currently has this as an open issue for the group. Here's the link for the post and here is the link for the tracked item. There is this control a third party created, however it appears to me like it is not very secure so use it at your own risk. I only mention it because it could be a potential band-aid depending on the needs of your project.

Browser automation in .Net

Can I automate actions like filling and submitting a form, clicking links et.c. in a real browser (i.e. IE11 or Firefox) using only a Silverlight or an XBAP application?
I would be grateful if you could let me know any other solution (other than the two above) that can do the automations without the need to manually install third party software (like Selenium or Telerik Testing Framework).
No one answered, so I'll tell you what worked and what not.
Silverlight solutions didn't work due to the Same-origin browser policy.
The XBAP solution actually worked. I created a new XBAP application and loaded it in my other application inside an iframe.
The user must accept the pop-up and the XBAP application opens a new WebBrowser control doing its stuff.
The whole thing only supports IE.

What if we don't host our silverlight Application when we first Create it?

As we all know very well..
whenever we create application inside silverlight it is asking us for hosting it
by dialogue box at given below.
My question is what if i unchecked the check box[Host the silverlight application in a new web site].
Means what kind of problem we have to face later if I don't host our Silverlight Application in any of the option given by dialogue box.
Basically it is not a problem at all. You can add a website at any time later.
In the project settings of a website there is a Silverlight tab. Under that you will find the option to add Silverlight projects to the website. This will setup the links to generate the XAP in ClientBin as well as giving you the option to create test pages for each Silverlight app added. The test pages will give you the sample JS you need to host your Xap later.
You will have to eventually host your application somewhere otherwise it will stay on your local harddrive and hardly reach any clients. So if you have an existing web site you could simply copy-paste the necessary javascript to this site later in order to embed your Silverlight application. In this case you can uncheck this checkbox.

How to access web application class into silverlight application

I am beginner in silverlight..I have created a silverlight project. When a new silverlight project is created it is automatically creating a silverlight application and one web application. I have added a class in both applications. Now I want to access a method of web application class into silverlight application class. Is it possible? I have tried to add web application reference to silverlight but VS is not allowing. Is there any another way to do??
What you need is called WCF. A really simple tutorial that should get you going is found here: How to call WCF methods from Silverlight controls
Fundementally WCF allows the silverlight client to make method calls on a class instance hosted on the web site.
Yes it is possible, but not in the normal way. A Silverlight assembly can only reference another Silverlight assembly (this is a limitation of VS2008, i don't know if it has been changed in VS2010).
What you need to do is add an existing file to your Silverlight project, when the file browse dialog opens you navigate to the class file you want to reuse, but instead of just clicking the Add button, click on the little down arrow on the button and choose Add as link - now the file will "exist" in both projects and can be used in both.
If you are going to do this repeatedly though, you will want to move those shared class files out into a separate assembly, do a project reference from your web app, and have the equivalent Silverlight class library mirroring it (sharing the files as links), and then project reference that Silverlight class library from your Silverlight app.

Facebook Connect in Silverlight

Is there a good way to get Facebook Connect onto a Silverlight page? All I really need is simple authorization/registration. I've looked into the facebook developer toolkit, but the documentation is more or less non-existent for Silverlight, and I didn't really get anywhere with it.
Is there a good tutorial or a working library for adding Facebook Connect into a Silverlight app? Or is the best way to run Silverlight in Windowwless mode with HTML overlayed on top?
Are you looking for something like that? http://apps.facebook.com/chatmotion/
Before developing this small test app i took a look at these samples: http://facebooktoolkit.codeplex.com/releases/view/39727
Make sure to download the newest source code of the Facebook Development Kit for .NET and build it yourself since the release version(January) didn't work for me correctly.
Let me know if you have any problems.
I've decided to use the WebBrowser control that was added in Silverlight 4 to accomplish this.

TestPage.aspx in silverlight

I am a beginner in silverlight. I want to know what is TestPage.aspx and TestPage.html in silverlight. Actually i have google it but din't get enough information. Can any one give me answer??
TestPage.aspx and TestPage.html are the pages which will host your Silverlight content. As you might know, Silverlight is just a project (not a web application) and needs a page that can host it.
These pages are created by default and help you to test your XAML content during your development, which you can later remove from your project.
TestPage.html is dynamically generated by the Silverlight application as part of the Debug process. If you take a look at the Debug tab for the application properties you will see an option to Dynamically generate a test page. If this is selected then you TestPage.html is created in the /Bin/Debug folder of your Silverlight application.
A better solution is to create a web application in the same solution as your Silverlight application then in the properties for the web application go to the Silverlight Applications tab and add your existing Silverlight app to the web project. Also make sure that the Silverlight checkbox is ticked in the Debuggers section of the Web tab of your web application.
