String concatenation is expensive 15
Exceptions may go unhandled 18
Uninitialized event handlers aren t treated gracefully 25
Division operation isn t consistent between types 30
Typeless ArrayList isn t type-safe 34
Type GetType() may not locate all types 39
Public key reported by sn exe is inconsistent 44
2 Visual Studio and Compiler Gotchas 46
Compiler warnings may not be benign 46
Ordering of catch processing isn t consist across languages 54
Type GetType() might fail at run-time 58
rethrow isn t consistent 60
Default of Option Strict (off) isn t good 65
Versioning may lead to Serialization headaches 70
Creating Web apps can be painful 83
Naming XML documentation for IntelliSense support isn t intuitive 87
vii
3 Language and API Gotchas 89
Singleton isn t guaranteed process-wide 89
Default performance of
Data ReadXML is poor 93
enum lacks type-safety 97
Copy Constructor hampers exensibility 102
Clone() has limitations 110
Access to static/Shared members isn t enforced consistently 121
Details of exception may be hidden 124
Object initialization sequence isn t consistent 129

Unit testing private methods is tricky 138
4 Language Interoperability Gotchas 146
Common Language Specification Compliance isn t the default 146
Optional parameters break interoperability 148
Mixing case between class members breaks interoperability 151
Name collision with keywords breaks interoperability 153
Defining an array isn t consistent 156
5 Garbage Collection Gotchas 160
Writing FinalizeO is rarely a good idea 161
Releasing managed resources in FinalizeO can wreak havoc 164
Rules to invoke base Finalize() aren t consistent 171
Depending on FinalizeO can tie up critical resources 173
Using Finalize() on disposed objects is costly 177
Implementing IDisposable isn t enough 180
Using the Dispose Design Pattern doesn t guarantee cleanup 189
6 Inheritance and Polymorphism Gotchas 192
Runtime Type Identification can hurt extensibility 192
Using new/shadows causes hideous hiding 202
Compilers are lenient toward forgotten override/overrides 205
Compilers lean toward hiding virtual methods 209
Exception handling can break polymorphism 211
Signature mismatches can lead to method hiding 218
viii Table of Contents
7 Multithreading Gotchas 223
The Thread class supports some dangerous methods/properties 223

ThreadAbortException—a hot potato 232
Environment ExitQ brings down the CLR 235
ResetAbort() may lead to surprises 238
Abort() takes time to clean up 240
Calling Type GetType() may not return what you expect 243

Threads from the thread pool are scarce 256
Threads invoked using delegates behave like background threads 260
Passing parameters to threads is tricky 263
Exceptions thrown from threads in the pool are lost 274

Default apartment of main thread is inconsistent across languages 318
STAThread attribute may have no effect on your methods 321
Spattering access to COM components makes code hard to maintain 325
Auto-generating GUID for your classes leads to versioning woes 327
All but one of the Classlnterface options are ineffective 332
