I'm a C# .NET Core developer. As mobile app development sells more, I hope to upgrade my career to a mobile app developer. I'm looking at Xamarin Forms or Java. What would you advise?

Thanks

I am using Sustainsys.Saml2 for Azure AD Saml authentication in .NET Core 3.1.i can able to authenticate, but after the login page is redirected to this address https://localhost:44378/Saml2/Acs.system automatically adding /Saml2/Acs.i could not find the correct tutorial for using this.

services.AddAuthentication(sharedOptions =>
            {
                sharedOptions.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                sharedOptions.DefaultSignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               sharedOptions.DefaultChallengeScheme = "Saml2";
            })
            .AddSaml2(options =>
            {
               options.SPOptions.EntityId = new EntityId("https://localhost:44378/Saml2");
                options.IdentityProviders.Add(
                new IdentityProvider(
                  new EntityId("https://sts.windows.net/9e5692e4-bd0a-414d-8b61-98f59dab156e/"), options.SPOptions)
                {
                    MetadataLocation = "https://login.microsoftonline.com/7e5692e4-bgf0a-4148-8b61-98f59dab156e/federationmetadata/2007-06/federationmetadata.xml?appid=1729db2f-0156-41cb-b4e3-d54bed555b85"
                });
            })
            .AddCookie();

            services.AddMvc(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));

Hi,

I am looking into solutions for reusable components for an existing #MVC project which is build on .NET Core. Currently some functionality is being reuses via JavaScript. I have React experience so I know I can create React components and then reference it on the MVC app. The only problem is I do not know the full extent of it as the current app uses a lot of 3rd party libraries, not sure how that will effect React components. I am currently looking into WebComponents which is also another way for creating reusable components and it is compatible with any JavaScript library based on what I have seen on the website. Also to take in consideration that it should cause a re-write of the system.

So my question is, to future-proof reusable components, which will be best React or Web Components? And which will be more reliable to use with 3rd party libraries?
