Quick Interview Answer

ASP.NET Core commonly distinguishes Development, Staging, and Production environments, although custom names are possible. Environment-specific behavior can control diagnostics, middleware, configuration, and development tooling.

Detailed Explanation

ASP.NET Core commonly distinguishes Development, Staging, and Production environments, although custom names are possible. Environment-specific behavior can control diagnostics, middleware, configuration, and development tooling.

Production behavior should not expose developer exception details merely because a configuration mistake leaves a diagnostic feature enabled.

Code Example

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
