Choosing Between Windows Forms and Web Forms

Programming model

Windows Forms is based on a client-side, Win32 message-pump mode, where instances of components are created, used, and discarded by the developer.

Web Forms relies on a largely asynchronous, disconnected model, where components are loosely coupled to the application front end. Typically, application components are invoked through HTTP. This model may not be suitable for applications requiring extreme throughput from the user end or for those with high-volume transactions. Similarly, Web Forms applications may not be suitable for database applications that require high levels of concurrency control (for example, pessimistic locking).

Security

Windows Forms uses permissions in its implementation of code access security to protect computer resources and sensitive information. This allows careful exposure of functionality, while retaining security. For instance, the Printing Permission, which at one level would allow printing to the default printer only, at another level would allow printing to any printer. Using ClickOnce, developers can easily configure which permissions their applications should and should not demand from the client. For more information, see ClickOnce Deployment and Security.

Authorization to gain access to the resources of a Web application is typically controlled on a per-URL basis by authenticating the credentials (for example, a name/password pair) of the requestor. Web Forms allows the developer to control the identity under which server application code is executed. Applications can execute code with the identity of the requesting entity, which is known as impersonation. Applications can also dynamically tailor content based on the requestor's identity or role. For example, a manager could receive access to a site, or a higher level of content than someone with lower permissions.

Every request to any ASPX page will create a separate instance of the page class, generally all in the same AppDomain.

There is no concept of a "user", although you can create one using cookies or session state.
