Hi Mina, No, the app = builder.Build() statement in ASP.NET Core does not create an .exe file for the web application. Explanation of app = builder.Build() Setup Pipeline: It takes the setup/configurations you've added through the builder (e.g., services, routing, middleware, etc.) and creates a fully functional web application. WebApplication Instance: The builder.Build() method generates an instance of the WebApplication class, which is the main entry point for the web app to start listening for requests. No .exe Generation: This process does not create an actual .exe file on disk. Instead, it prepares the runtime environment for your application to be executed when run through the .NET Core runtime. The hosting environment handles the execution of your web app.

No, calling WebApplication app = builder.Build() does not create an executable (exe) file. The actual executable file (.exe) for your web application would have already been created when you compiled the project (typically in the bin folder). The Build() method simply finalizes the application's configuration so that it's ready to be run, but it doesn't generate an .exe file on its own.
