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 my Startup.cs?

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

Can you provide a code example for the configuration?

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,
        ValidIssuer = "yourIssuer",
        ValidAudience = "yourAudience",
        IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("yourSecretKey"))
    };
});

What should I do if I encounter errors during implementation?

Check the error messages in your console, ensure your OAuth provider settings are correct, and verify your redirect URIs.
