Server-side web hosting is an increasingly important way of deploying applications. We discuss how to develop these applications in 14, and in this section we briefly discuss techniques to deploy ASP.NET web server applications. Here are your typical choices for deploying these applications: Copying your source files to the web server using FTP, XCOPY, or any other similar file transfer tool or protocol. Alternatively, you can use the Website/Copy Web Site option in Visual Studio. Compiling your web application into a set of DLLs and deploying them using Build/Publish Web Site in Visual Studio. Here you have the option of including source code in the deployment. Creating an installer that deploys your web application into the IIS installed on the target computer. The first option requires you to be able to log on to the web server and place files either via FTP or as a web administrator. Probably the most versatile tool for manual copying of your website is the Copy Web Site dialog box in Visual Studio, which enables you to easily copy or synchronize files between your local copy and the remote web server. For the remote website, you can choose a directory on your local file system, a web folder under your local IIS, an FTP site and directory within, or a remote website configured with the FrontPage Server Extensions. One problem with manual copying is that each updated page has to be compiled on the server as it is first requested. To remedy this problem, you can precompile your site using the second option. In the Publish Web Site dialog box you can control how your site is precompiled and where it is deployed. The target location can be of any type discussed previously for establishing a connection for manual copy. For the third option, to create an installer for your web application, Visual Studio provides the Web Setup Project type under Other Project Types/Setup and Deployment in the New Project dialog box. This project type is a customized form of the setup project.

Another option you have besides the web setup project is to install the Web Deployment Project Visual Studio add-in. This add-in adds a new menu item, Build/Add Web Deployment Project, in Visual Studio that you can use to add a deployment project to your web application solution. In the Options dialog box of your deployment project, you can customize the compilation, output, signing, and deployment aspects of your web setup.

Summary

In this chapter, you learned about a number of issues related to encapsulating, organizing, and packaging code, from the raw language devices used for accessibility and encapsulation within code to building assemblies and the related topics of packaging applications, building DLLs, and including data resources as part of your libraries and applications. Finally, we gave some tips on how build installers and deploy web applications. In the next chapter, we ll look at some of the foundational techniques you will need to master as you progress with learning to program in F#.

# is a powerful language with relatively simple constructs. Learning the constructs of the language is easy, but learning how to use the constructs well takes a little more time. In this chapter, we present some of the common F# coding techniques you will need as you work across multiple programming domains. These techniques are either applications of the constructs we ve encountered so far or relate to the foundational libraries that ship with F# and .NET.

In 5 you saw a number of predefined generic operations, including generic comparison, equality, and hashing, accessed via functions such as those shown here: val val val val val val val val val compare : 'a -> 'a -> int (=) : 'a -> 'a -> bool (<) : 'a -> 'a -> bool (<=) : 'a -> 'a -> bool (>) : 'a -> 'a -> bool (>=) : 'a -> 'a -> bool min : 'a -> 'a -> 'a max : 'a -> 'a -> 'a hash : 'a -> int

In this section, we cover how to customize the behavior of these functions for new type definitions. It s important to note that generic comparison is not implemented using reflection; instead, code is autogenerated for each record and discriminated union type definition. This code implements comparison efficiently and often uses fast path comparison techniques. For example, the generated code will use primitive IL/native instructions for integer comparisons. This means in practice generic comparison is fast when used with appropriately sized keys. You can modify the default implementation of generic comparison for new type definitions by implementing the interface System.IComparable and overriding the method Equals from the .NET type System.Object. Listing 8-1 shows an example, taken from the F# library implementation of the Microsoft.FSharp.Math.BigInt type, which is implemented in terms of
