Steps to implement SAML 2.0 using C# - c#-4.0

I am trying to implement SAML 2.0 in my project(c#). I researched and found the work flow. However I am a little confused with the steps from a coding perspective. Please help

SAML is not a simple protocol.
I suggest you use a SAML client side stack. There are some recommendations - refer SAML : SAML connectivity / toolkit.

Azure SAML Authentication in Flask Web App

I'm trying to configure a SAML Authentication with Azure in a Flask web service.
Is the first time I'm doing this and I'm bit lost.
I'm trying to use the 'SAML_METADA_URL' provided in AZURE but I don't know what to configure in python side.
In Azure seems to be all setup, the app was added, have the client ID and CLIENT SECRET, ETC.
Anyone knows a good and specific tutorial for this?
Thanks in advance
You can refer to the SAML-enabled Python application guide, which explains how to use PySAML2 to add Okta support (via SAML) to an application written in Python, And refer to the steps for implementing a SAML SP in Python/Flask.
In addition, OneLogin also provides a SAML Python toolkit, I believe it will also be helpful to you here.

Azure Bot framework V4- SSO implementation

Creating a Azure chatbot V4 framework. But not able to see any proper documentation on SSO implementation so far. Is it possible to have single sign on in version 4 or not? can somebody give pointers please?
Yes. It's absolutely possible to have SSO in v4 framework. In the documentation there is a part about implementing authentication here:
https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-authentication?view=azure-bot-service-4.0&tabs=aadv1%2Ccsharp%2Cbot-oauth
For webchat channel itself there is a fresh (released last month) sample of implementing SSO with Oauth here:

SAML 2.0 using ADAL4j

Am experimenting SAML 2.0 SSO from a java web application using Azure AD as IDP.
I modified the sample - https://github.com/Azure-Samples/active-directory-java-webapp-openidconnect
to generate a SAML request.
But am getting the below error -
AADSTS75005: The request is not a valid Saml2 protocol message
I tried using OpenSAML library to generate SAML Request.
I would like to know if ADAL4J supports SAML 2.0. If yes, can someone share a sample?
Thanks in advance.
ADAL is a wrapper around a protocol.
Currently, that protocol is OpenID Connect / OAuth.
You need a client side SAML stack.
A lot of Java applications use Spring security.
I think I faced the same or similar problem, and I've found that I am receiving response from custom identity provider in SAML1.1 standard, but ADAL4J recognizes it as SAML2.0 . What I had to do is use modified library, with changed implementation of method isTokenSaml2() in WSTrustResponse class (I've added a lot of additional logging in ADAL4J too). Token type extracted from response was other than expected - "urn:oasis:names:tc:SAML:1.0:assertion"

OAuth 2.0 Authentication and Authorization

I have a web service written in node.js and I have a server that is running MongoDB, my question is, how can I implement OAuth 2.0 when according to RFC 6749 in my case, the resource owner, the resource server and the authorization server are the same? i.e. I want to use OAuth to authenticate and authorize users that are in my own database and not from other resource owners(like facebook or twitter).
This is a pretty broad question -- implementing oauth is quite complex if you're looking to roll your own solution.
If I were you I'd look into using a library like Passport.js or Stormpath to help offload this stuff.
You can find detailed generic information about what developers have to do to implement OAuth 2.0 and OpenID Connect in Authlete Definitive Guide and Authlete Blog. Although the documents refer to a specific solution (Authlete), the contents will serve as a useful reference for developers who dare to implement their own OAuth 2.0/OpenID Connect servers.

OpenID Connect will eventually replace SAML as the dominant protocol for SSO?

I have seen in the some articles, It is said that OpenID Connect would replace SAML as the dominant protocol for SSO. I am not sure how openID connect would handle the session management capabilities with different service providers and how it could be used to implement single logout? Currently, Are there are IDM servers (open source or commercial) that supports OpenID connect as a SSO IDP (as replacement for SAML2 SSO IDP)?
PingFederate [disclaimer: as it says in my name, I work for PingIdentity] built OIDC into the product in April 2013 - version 7.0. Additionally, we've supported OpenID since December 2010 via an integration kit.
That said, "SLO" (Single Logout) under OIDC is a whole new ballgame. I'd suggest having a read through the Session Management portion of the OID Spec. The gist of it is that SLO is done completely different than the way most SAML systems implemented it, and it's very user-centric, rather than OP or RP specific.
One last thing... While it's possible that OIDC will replace SAML eventually, I'd just like to point out that we've finally got a serious snowball effect going with SAML. OIDC isn't yet final, and it's going to take time to migrate to. Will the focus shift? Quite possible. But it won't happen this year, or next, and most likely not for a couple more after that. If you're looking at products that are bleeding edge that support OIDC, fair enough... But if you're actually wanting to implement, the opportunities are few and far between. There just aren't a lot of RPs out there yet - primarily because the spec isn't "final".
I should also mention that some of our competitors, like Gluu, Okta, IBM, and Layer7 have shown support for OIDC (by competing in interop testing), but I can't speak to the extent of their support in current products.
OpenAM seems to support it from release 11. wikis.forgerock.org/confluence/display/openam/OpenAM+Roadmap
Yes, no question. No one wants to use a SOAP/XML standard from 2005 (pre-mobile) when they can use a JSON/REST API from 2014. See Gluu's protocol predictions: http://www.gluu.co/sso-protocol-predictions
If you doubt it, see Forrester's predictions...

Notice SAML on the "moderate success" curve, and OpenID Connect on the "significant success" curve.
The problem is that SAML vendors would not agree to breaking changes, and mobile/headless API's broke some of the assumptions made in the design of SAML.

I would expect that OIDC will replace SAML based authentication over time.
Apache Fediz (since version 1.3.0) provides support for
* SAML Web SSO
* WS-Federation
* OIDC
The great think about Fediz is, that is also supports a protocol bridge.
So you can login with an IDP using SAML Web SSO and finally login to an OIDC Web Portal.

However SLO is currently not supported for OIDC. But since it is an open source project it should be simple to add this, as contributions are always welcome.
