各种各样的 Host Buider

If you're building for the web or writing a distributed application, you might need to use a different host builder. Consider the following list of additional host builders:

• DistributedApplicationBuilder: A builder for creating distributed apps. For more information, see .NET Aspire.
• WebApplicationBuilder: A builder for web applications and services. For more information, see ASP.NET Core.
• WebHostBuilder: A builder for IWebHost. For more information, see ASP.NET Core web host.
