How is the using() pattern useful? What is IDisposable? How does it support deterministic finalization?
The using() pattern is useful because it ensures that Dispose() will always be called when a disposable object (defined as one that implements IDisposable, and thus... Read more »
What are PDBs? Where must they be located for debugging to work?

What is the use of Internal keyword?

Why only boxed types can be unboxed?

Why doesn’t the .NET runtime offer deterministic destruction?
Because of the garbage collection algorithm. The .NET garbage collector works by periodically running through a list of all the objects that are currently being... Read more »
Is the lack of deterministic destruction in .NET a problem?
It’s certainly an issue that affects component design. If you have objects that maintain expensive or scarce resources (e.g. database locks), you need to provide... Read more »
What is serialization?
Serialization is the process of converting an object into a stream of bytes. Deserialization is the opposite process of creating an object from a stream of bytes.... Read more »
Can I customise the serialization process?
Yes. XmlSerializer supports a range of attributes that can be used to configure serialization for a particular class. For example, a field or property can be marked... Read more »
Why is XmlSerializer so slow?
There is a once-per-process-per-type overhead with XmlSerializer. So the first time you serialize or deserialize an object of a given type in an application, there... Read more »
What are attributes?
There are at least two types of .NET attribute. The first type I will refer to as a metadata attribute - it allows some data to be attached to a class or method.... Read more »
How can I stop my code being reverse-engineered from IL?
There is currently no simple way to stop code being reverse-engineered from IL. In future it is likely that IL obfuscation tools will become available, either from... Read more »
Differnce between Managed code and unmanaged code ?

What is Reference type and value type ?
Reference Type: Reference types are allocated on the managed CLR heap, just like object types. A data type that is stored as a reference to the value’s location.... Read more »
What is difference between constants, readonly and, static ?
Constants: The value can’t be changed Read-only: The value will be initialized only once from the constructor of the class. Static: Value can be initialized once. Read more »
