.NET CLR Common Features  Verifiable type safe execution  No uninitialized variables, unsafe casts, bad array indexing, bad pointer math  Garbage Collection  No ref-counting, no leaks  JIT compilation  Error handling with exceptions  Common type system  Call, inherit, and source-level debug across different languages

Compact CLR Differences  COM Interop  Good support for calling native DLLs  Support for calling a COM object through DLL wrappers  No support for writing a COM / ActiveX object  No Install-time JIT (nGen) / No Reflection Emit  No Remoting / Client web services is fully supported  No Generic Serialization  Datasets can be serialized to XML  Subsets of other areas of functionality

Developing Games for Smart Device App using.NET CF

.NET Framework CLR Size  Framework size (RAM or ROM)  ~1.5 MB  Running RAM needs  1 MB+ (depends on app)  Typical application sizes  KB  Apps often smaller due to use of platform features in the framework

.NET Compact Framework - Features  Base Classes  Data/XML  XML Web Service Client  Threading  Native Code Interop  Globalization  Windows Forms Support
