ASP.NET Core is Microsoft's cross-platform web framework, tied for the largest professional-developer framework audience (2025 SO survey, 21.3%). Its Identity system defines a pluggable IEmailSender (and, since .NET 8, the generic IEmailSender<TUser>) specifically so account-confirmation and password-reset mail can be swapped in with one interface implementation.

Connect ASP.NET Core to MailKite

dotnet add package MailKite.AspNetCore, then AddMailKiteEmailSender() — every Identity confirmation/reset email routes through MailKite. See /docs/integrations/aspnet-core.
