Authentication with Azure Active Directory connected services missing in existing Asp.Net core application

Question

I have existing Asp.net core 2.0 application. I am trying to add Authentication with Azure Active Directory connected service to it. When I tried to right click on connected services and checked for Authentication with Azure Active Directory connected service, I did not find the option. I searched online and found that for existing asp.net core applications there is not connected service option. What will be the work around in this case? any hints?

You can try below steps :

Install the package : Microsoft.AspNetCore.Authentication.AzureAD.UI

Modify the Startup.cs to enable Azure AD Authentication:

services.Configure<CookiePolicyOptions>(options =>
{
    // This lambda determines whether user consent for non-essential cookies is needed for a given request.
    options.CheckConsentNeeded = context => true;
    options.MinimumSameSitePolicy = SameSiteMode.None;
});

services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
    .AddAzureAD(options => Configuration.Bind("AzureAd", options));

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

Add the authentication middleware to Configure :
```
app.UseAuthentication();
```

Modify the appsettings.json to add the Azure AD app settings

{
"AzureAd": {
    "Instance": "https://login.microsoftonline.com/",
    "Domain": "xxxxxxx.onmicrosoft.com",
    "TenantId": "xxxxxx-e83b-4099-93c2-8ae86358d05c",
    "ClientId": "xxxxxxxx-80c5-4bd4-ad6a-a967ea0066d6",
    "CallbackPath": "/signin-oidc"
},
"Logging": {
    "LogLevel": {
    "Default": "Warning"
    }
},
"AllowedHosts": "*"
}

Another way is to config the OpenId Connect Middlerware manually , you can refer to below article :
