You can also factor managed code out into a separate DLL so that your existing projects remain completely unmanaged. Figure 1-4 shows a simple example of such a scenario.

Figure 1-4. Separating managed code in DLLs In this simple scenario, TheApp.cpp shall represent your existing project. To extend it with managed features, a new DLL is created from the source file TheLib.cpp. Notice that TheLib.cpp is compiled with /clr. Therefore, the exported function f() is a managed function. When main calls the managed function f, the CLR is delay-loaded. Using mixed-code DLLs like TheLib.dll from the preceding sample, you can minimize the impact that managed execution has on your project. However, there are some pitfalls that you should know before you start writing mixed-code DLLs. 12 gives you all the necessary information to avoid these pitfalls.

So far, I have discussed the following two major features, sometimes summarized as C++/CLI interoperability: Existing C++ source code can be compiled to managed code (source code compatibility). Native code and managed code can be linked into a mixed-code assembly (object file compatibility). Compared to the interoperability features that other .NET languages provide, C++/CLI interoperability is much more powerful. It is a significant simplification for interoperating with native code, and it enables developers to save huge investments of existing C++ code. On the other hand, these powerful features have side effects. Often, these side effects can be ignored, but it is also possible that these side effects are incompatible with other constraints and requirements of a project. To handle situations that are incompatible with the side effects caused by C++/CLI interoperability, Visual C++ allows you to turn either the object file compatibility or both C++/CLI interoperability features off. This can be done by choosing different compilation models supported by Visual C++. If the command-line option /clr is not

used, the compiler chooses the native compilation model. To compile to managed code, the compiler argument /clr, or one of its alternatives /clr:pure or /clr:safe can be chosen. As shown in the preceding samples, the /clr compiler option enables you to use both interoperability features mentioned previously. The compiler option /clr:pure still allows you to compile existing C++ code to managed code (source code compatibility), but you cannot produce mixed-code assemblies, which would require object file compatibility. The linker does not allow you to link object files produced with /clr:pure with native object files. An assembly linked from object files compiled with /clr:pure will have only managed code; hence the name. Assemblies containing only managed code can be used to bypass two special restrictions of mixed-code assemblies. However, these restrictions apply only to very special scenarios, and understanding them requires knowledge of .NET features discussed later in this book. Therefore, I defer this discussion to 7. Another restriction that applies to mixed-code assemblies as well as to assemblies built with /clr:pure is much more relevant: neither kind of assembly contains verifiable code, which is a requirement for .NET s new security model, called Code Access Security (CAS). CAS can be used to execute assemblies with restricted abilities to use features of the runtime and base class libraries. For example, pluggable applications are often implemented so that plug-ins do not have any permission on the file system or the network. This is sometimes called sandboxed execution. Certain features of the runtime could be misused to easily bypass a sandbox of restricted permissions. As an example, all features that allow you to modify random virtual memory could be used to overwrite existing code with code that is outside of the runtime s control. To ensure that none of these dangerous features are used by a sandboxed assembly, its code is verified before it is actually executed. Only if code has passed the verification can it be executed in a sandbox. The powerful interoperability features that are supported with the compilation models /clr and /clr:pure use nonverifiable features intensively. To produce verifiable code, it is required to use the compilation model /clr:safe. Source code that is compiled with /clr:safe can only contain .NET constructs. This implies that native C++ types cannot be used.
