Figure 9-4. Native classes compiled to managed code can be used by native clients. IL metadata is not aware of C++ classes. Therefore, the C++/CLI compiler generates two global functions with the mangled names SampleClass.F1 and SampleClass.F2 for the two member functions of SampleClass. Since F1 and F2 are non-static member functions of SampleClass, they have a hidden this pointer argument of type SampleClass * const. To define this argument of both methods, the C++/CLI compiler generates a managed proxy type, as described in 8: .class private sequential ansi sealed beforefieldinit SampleClass extends [mscorlib]System.ValueType { .pack 0 .size 1 // [NativeCppClassAttribute] .custom instance void [mscorlib]System.Runtime.CompilerServices.NativeCppClassAttribute::.ctor() = ( 01 00 00 00 ) // other attributes elided for clarity here } In the sample application, both member functions are called from native code. Therefore, the compiler emits .vtentry and .vtfixup metadata for SampleClass.F1 and SampleClass.F2: .method assembly static void modopt(System.Runtime.CompilerServices.CallConvThiscall) SampleClass.F1(valuetype SampleClass*

In this chapter, I ve focused on the theory behind distributed systems specifically, those based on mobile objects. The key to success in designing a distributed system is to keep clear the distinction between a logical architecture and a physical architecture. Logical architectures exist to define the separation between the different types of code in an application. The goal of a good logical architecture is to make code more maintainable, understandable, and reusable. A logical architecture must also define enough layers to enable any physical architectures that may be required. Physical architectures define the machines on which the application will run. An application with several logical layers can still run on a single machine. You also might configure that same logical architecture to run on various client and server machines. The goal of a good physical architecture is to achieve the best trade-off between performance, scalability, security, and fault tolerance within your specific environment. The trade-offs in a physical architecture for a smart client application are very different from those for a web application. A Windows application will typically trade performance against scalability, and a web application will typically trade performance against security. In this book, I ll be using a 5-layer logical architecture consisting of the Interface, Interface Control, Business, Data Access, and Data Storage and Management layers. Later in the book, I ll show you how to use this architecture to create Windows, web, and service-oriented applications, each with a different physical architecture. The next chapter will start the process of designing the framework that will make this possible.

n 1, I discussed some general concepts about physical and logical n-tier architecture, including a 5-layer model for describing systems logically. In this chapter, I take that 5-layer logical model and expand it into a framework design. Specifically, this chapter will map the logical layers against the technologies illustrated in Figure 2-1.

modopt([mscorlib]System.Runtime.CompilerServices.IsConst) modopt([mscorlib]System.Runtime.CompilerServices.IsConst) A_0) cil managed { .vtentry 1 : 1 // ... managed code of SampleClass::F1 elided for clarity } .method assembly static void modopt(System.Runtime.CompilerServices.CallConvStdcall) SampleClass.F2(valuetype SampleClass* modopt([mscorlib]System.Runtime.CompilerServices.IsConst) modopt([mscorlib]System.Runtime.CompilerServices.IsConst) A_0) cil managed { .vtentry 2 : 1 // ... managed code of SampleClass::F2 elided for clarity } As with global functions, the compiler generates an interoperability vtable containing an address to the unmanaged-to-managed thunk. When the assembly is loaded, the CLR generates the thunk and stores its address in the interoperability vtable. The native caller can then use the interoperability vtable to invoke the thunk that calls the member functions. It you switch the compilation models of the source files in the preceding sample, native member functions are called by a managed client. Consequently, the following P/Invoke metadata will be generated in this case: .method public static pinvokeimpl() void modopt([mscorlib]System.Runtime.CompilerServices.CallConvThiscall) SampleClass.F1(valuetype SampleClass* modopt([mscorlib]System.Runtime.CompilerServices.IsConst) modopt([mscorlib]System.Runtime.CompilerServices.IsConst) A_0) native unmanaged preservesig { .custom instance void System.Security.SuppressUnmanagedCodeSecurityAttribute::.ctor() = ( 01 00 00 00 ) // Managed TargetRVA = 0x00001000 }

Functions pointers can also be used to cross interoperability boundaries in both directions. Figure 9-5 shows a simple application with a managed entry point main that calls a native function fTarget via a function pointer.
