You might not always want to embed interop information. It might be that in your deployment scenario, you can always rely on the PIAs being present perhaps your application will only ever run on machines on which you have preinstalled the relevant components. In this case, installation of PIAs is a nonissue for your application, and the additional space required by embedding becomes pure overhead. So you can turn the feature off. Interop type embedding is controlled per-reference, and is on by default for a newly created reference. If you select an interop assembly in your project s References in the Solution Explorer, the Properties panel will offer an Embed Interop Types setting. Changing this to False reverts to the old behavior of relying on the PIA.

Interop with unmanaged code raises a challenge on 64-bit systems. Whether you re using COM components such as ActiveX controls, or plain old unmanaged DLLs, you need to be aware of whether the code you wish to use is 32-bit or 64-bit; you need to know its bitness, as it s sometimes called. If you ignore this issue, there s a risk that your code will not work on 64-bit versions of Windows. In general, it s not possible for a single piece of machine code to execute successfully in both 32-bit and 64-bit environments you need different binary code. The 64-bit Intel Itanium has a CPU architecture that is a radical departure from the x86 system used in 32-bit Windows the machine understands an entirely different set of instructions in 64-bit mode. The more popular x64 architecture you ll find in most 64-bit PCs has a lot more in common with its x86 predecessor, but even so, you need different binary in 32-bit and 64-bit modes. The only reason existing 32-bit applications can run at all on 64-bit versions of Windows is that 64-bit Windows can host 32-bit processes. (You can see which these are in the Windows Task Manager s Processes tab the 32bit processes all have *32 in the Image Name column. Obviously, you ll see this only if you re running 64-bit Windows, as the information would be redundant on a 32-bit system.) Windows puts the CPU into a different mode for these processes its 64-bit features are hidden, enabling legacy 32-bit code to run.

Despite this, .NET programs often don t need to care about bitness. C# compiles into a CPU-independent intermediate language which is compiled just in time (JIT) into executable code when the program runs. If you run your code on a 32-bit version of Windows (or in a 32-bit process on 64-bit Windows), the CLR will JIT-compile your program into 32-bit code. If you re running in a 64-bit process, it will JIT-compile into 64-bit code instead. This means you don t have to commit to a particular bitness when you write the code. Unmanaged code doesn t have this luxury, because the executable binary code gets created at compile time the developer has to tell the C++ compiler whether to produce 32-bit or 64-bit code. So if you re using an unmanaged DLL or a COM component, it will be capable of running in only one bitness. A process in Windows cannot contain a mixture of 32-bit and 64-bit code bitness is fixed per-process. If you attempt to load an unmanaged 32-bit component into a 64-bit process, Windows will refuse. If it s a COM component (e.g., an ActiveX control) you ll get a COMException, with this error text:

In some more sophisticated ACL schemes, another piece of information called a role is added, which enables a user or principal to access particular resources. Table 1-2 shows an example mapping of users to roles, and Table 1-3 shows a role-based ACL. In Table 1-2, Alice is both a programmer and an administrator, and Bob is both a programmer and a backup operator.3 Table 1-2. A User-Role Mapping

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

This can be perplexing if the component you require appears to be installed. But what s happened here is that .NET went looking for a 64-bit version of the component, and it didn t find one, so it complains that the COM class you were looking for does not seem to be installed.

Other blocks are specific to a particular service, like the MSN News Feeds block shown in Figure 7-2, which has the MSN RSS news feeds preconfigured, so you don t need to supply the URLs of each of feeds to the mashup creator.

It s possible to install both 32-bit and 64-bit versions of COM components, in which case you wouldn t get this error. However, that s relatively uncommon. Most ActiveX controls are 32-bit.
