Answer
CORS allows cross-domain API access.
Configured using AddCors + middleware.
Needed for browser-based clients.
Quick Answer
CORS (Cross-Origin Resource Sharing) restricts which origins can make requests to your API from browsers. Configure in Program.cs: builder.Services.AddCors() and app.UseCors(). Define policies: AllowAnyOrigin(), WithOrigins("https://yourapp.com"), AllowAnyMethod(), AllowAnyHeader(). Apply globally or per controller/action. Allow only specific trusted origins - avoid AllowAnyOrigin in production.
