It should be noted, though, that most untrusted code is not actually intended to be malicious; it is just written in such a way so as to be taking too long by the host s standards . Usually, catch and finally blocks contain very little code, and this code usually executes quickly without any infinite loops or long-running tasks . And so it is very unlikely that the escalation policy will have to go into effect for the host to regain control of its thread . By the way, the Thread class actually offers two Abort methods: One takes no parameters, and the other takes an Object parameter allowing you to pass anything . When code catches the ThreadAbortException, it can query its read-only ExceptionState property . This property returns the object that was passed to Abort . This allows the thread calling Abort to specify some additional information that can be examined by code catching the ThreadAbortException . The host can use this to let its own handling code know why it is aborting threads .

This chapter is all about discovering information about types, creating instances of them, and accessing their members when you didn t know anything about them at compile time . The information in this chapter is typically used to create a dynamically extensible application . This is the kind of application for which one company builds a host application and other companies create add-ins to extend the host application . The host can t be built or tested against the add-ins because the add-ins are created by different companies and are likely to be created after the host application has already shipped . This is why the host needs to discover the add-ins at runtime . A dynamically extensible application could take advantage of common language runtime (CLR) hosting and AppDomains as discussed in 22, CLR Hosting and AppDomains . The host could run the add-in code in an AppDomain with its own security and configuration settings . The host could also unload the add-in code by unloading the AppDomain . At the end of this chapter, I ll talk a little about how to put all of this stuff together CLR hosting, AppDomains, assembly loading, type discovery, type instance construction, and reflection in order to build a robust, secure, dynamically extensible application .

As you know, when the just-in-time (JIT) compiler compiles the Intermediate Language (IL) for a method, it sees what types are referenced in the IL code . Then at runtime, the JIT compiler uses the assembly s TypeRef and AssemblyRef metadata tables to determine what assembly defines the type being referenced . The AssemblyRef metadata table entry contains all of the parts that make up the strong name of the assembly . The JIT compiler grabs all of these parts name (without extension or path), version, culture, and public key token concatenates them into a string, and then attempts to load an assembly matching this identity into the AppDomain (assuming that it s not already loaded) . If the assembly being loaded is
