i am developing a notification service in c# for our web site. its windows service no ui (asp.net / winform). This service will run on certain time and post something on users wall. i use social plug-in in our web site where user can grant required permission. Based on this i have few question
1) is there any c# library or sdk available for Facebook.
2) what information i have to store in order to access facebook offline.
i hope my question is clear. thanks for any help.
Update 1: i really need help on this. thanks once again.
There is a facebook API that can be used, http://developers.facebook.com/
You can't access facebook offline? I mean, if you wanted to save current information while online and then re-access the old information while offline that is possible just by saving the webpages, but you cannot access any new information. so your not really accessing facebook..
You'll need the user to log in, and there's a permission you can request that makes the session you get permanent. You'll have to have some kind of installer or something that will have the user log in, grant that permission, and then you'll save that access token. UI-wise, look at digsby, and notice how they make you log in to facebook the first time you link your facebook account.

I have a web app (rest API) on azure, and I have a B2C setup that is securing it, requiring you to be signed in to access the API. This is good, as i wanted the API to be restricted to members. Basically, the entire web app requires authentication, and will prompt you for a sign in.
Heres the problem - my app has users (who have accounts) and clients (who do not have accounts). These clients might receive an email about a new appointment being set up with one of the users - this email should have one or more links/buttons (ie, a button to Confirm appointment, one to Decline, and one to request a reschdeule) and upon clicking this link I would like to update a field in my database via the rest api, so the USER knows the CLIENT's response. The trouble is, since the client wont have an account, I have no idea how I can give them a link they would be allowed to go to, and have the update happen.
I have tried to do a bunch of research - ive looked into AD external identities with a one time passcode - but i cant seem to find any info on how i would actually get this to work for my purposes.
Does anyone know how I might implement this in azure? Is there a way to call to azure form c# to generate a one time authentication that i can encode into a URL or something?
Any thoughts would be greatly appreciated.
Thanks!
You could do an anonymous authentication by using a magic link. The users account won’t even need to live in the directory. The link can be short lived, and potentially one time use. We call it id_token_hint or a magic link.

Hi everyone I have a problem I wanna create app for generate account google drive with api google drive and I don't know how can I login with account from application not navigator C# windows form.
enter image description here
and how can i edit this credential with exist user
Try following these steps:
https://learn.microsoft.com/en-us/aspnet/core/security/authentication/social/google-logins?view=aspnetcore-3.1
I have used those steps and worked perfectly for me. You don't have a choice than to be redirected to the Google authentication page.
After entering your Google credentials, you are redirected back to the your site.
My understanding is that you are trying to use Google Drive API from a console application. Or for that matter a fully desktop application.
Take one thing in consideration, if you don't use Service account you must let the user authenticate to google and allow your application to work in his/her behalf. There is no way around this.
What you can do is after the user has already signed in, is to save the tokens and refresh them whenever necessary.
Of course OAuth may be complicated, but you use the .NET library everything will be managed for you. And you can look at a real example in the .NET Drive Quickstart
My company has an internal application where I need to pull/display pictures of all the employees from office 365 with out user intervention.
From what I read online I think I need to call Microsoft graph getphoto API in daemon application to achieve this as per this link (https://developer.microsoft.com/en-us/graph/docs/authorization/app_only).
Will this be a right approach? If yes please point me to any C# sample codes related to this.
Appreciate your responses.
Yes, this is exactly the type of application you will want to build. App-only (machine-to-machine) authentication should be used anytime you don't need a user present to execute functionality.
You can take a look at the ASP.NET Core App Only sample to get a sense of how to register and set up your app to use app-only authentication. The sample goes on to use this access token to set up webhooks, but you can replace this logic with your custom code. You will want to select the scope User.ReadBasic.All to have access to users' profile photos.
I have been tasked with creating a console app in asp.net (c#) to query a Sharepoint online list. I can connect to SharePoint using SharepointOnlineCredentials but the user is asked for credentials every time the app is run. Ideally we would like the app to ask the user for the details the first time it runs, save the information and only ask again when or if the users password expires.
I have very little experience with credential and authentication and I do not know the best way to proceed. Would I need to create an encrypted file or could I store a token? Or is there another means of achieving the objective?
Any advise and/or code examples would be appreciated.
Here you can use the Credential Locker
You can download the examples in the page.
Also you will use the PasswordVault class, you can find more information about PasswordVault
The best is to use the Windows API directly in this case. Somethign you will do if you fallow the documentation in the links.
I hope this help you, maybe you will have to do some research and check if there are any issues with asp.net since i did implemented once with a local C# Console app.
Good luck mate.
I'm just about to start a new ASP.NET project using MVC3, and since some of the requirements are about facebook integration, I need your advice on the following issues:
1- Is it achievable to connect my Membership users to thier Facebook accounts so whenever a user share/add/comment on an event on my website, I can automatically share these actions using his/her Facebook account?
2- also the ability to create Facebook events when the user create one on my site, and if he/she updates the event information, I may update them on Facebook too.
3- Can this be achieved using Facebook Connect, or this is only to authenticate users using their Facebook accounts?
4- How about using Graph API from my MVC solution, I know that there is a Facebook C# SDK on Codeplex http://facebooksdk.codeplex.com, but will it satisfy my mentioned needs or not.
Thanks in advance.
I've done something similar recently. Based on my experience:
Yes, you can connect your membership with a Facebook account, however it does not guarantee your user activity will be pushed to Facebook. (users have to log in with Facebook authentication)
Same as above. This blog post does a good job of describing it: http://amirrajan.net/Blog/asp-mvc-and-facebook-single-sign-on
No, facebook connect only takes care of authentication. For more information, check: http://thinkdiff.net/facebook/graph-api-javascript-base-facebook-connect-tutorial/
I have not tried the Facebook SDK you mentioned. However, I believe facebook Graph API already does a good job for you to and will fulfil your requirement
