How can I implement OAuth in my ASP.NET application?

To implement OAuth in your ASP.NET application, you can use the Microsoft.AspNetCore.Authentication.OAuth package. First, install the package via NuGet.

What are the steps to configure OAuth in Startup.cs?

In Startup.cs, you need to add the OAuth authentication services in the ConfigureServices method and configure the middleware in the Configure method.

Can you provide an example of the configuration code?

Sure! Here's a basic example:

services.AddAuthentication(options => {
    options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
    options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
})
.AddJwtBearer(options => {
    options.TokenValidationParameters = new TokenValidationParameters {
        ValidateIssuer = true,
        ValidateAudience = true,
        ValidateLifetime = true,
        ValidateIssuerSigningKey = true,
        // Add your issuer and audience here
    };
});

What about handling tokens?

You can handle tokens by creating a controller that issues tokens upon successful authentication and validates them on subsequent requests.
