A Literal Web Server control doesn't have any VISUAL appearance on a Web Form but is used to insert literal text into a Web Form. This control makes it POSSIBLE to ADD HTML code directly in the code designer WINDOW without switching to design view and clicking the HTML button to edit the HTML.

WINDOWS services are LONG running executable applications that typically do not possess any user interface, are controlled by the Service Control Manager (SCM) and can even be configured to start automatically after the SYSTEM boots. They typically EXECUTE in their own windows sessions. They can execute even if the user has not logged in to the system. They can even be started, paused, re-started manually. These applications are somewhat similar to the daemon PROCESSES of UNIX in the sense that they remain dormant most of the time and execute in the background as and when needed.

DUE to IntelliSense of Visual Studio.

If the select clause was in the first of LINQ, then the IDE cannot populate the properties INSIDE the object.

Eg:from F in db.Forum where f.Id > 0 select f.Name;

If the select was in FRONT - the "select f." could not populate any autocomplete properties or methods.

USE .Net Reflection. Using reflection we can invoke PRIVATE methods too.

Example:

Car car = new Car();
Type type = car.GetType();
MethodInfo methodInfo = type.GetMethod("ShiftGearUp", BindingFlags.NonPublic | BindingFlags.Instance);
methodInfo.Invoke(car, NULL);

 Pre: CREATE a class Car with private method "ShiftGearUp"

var gets processed in the compile time itself and shows any ERROR during compile time itself.

dynamic gets processed in the runtime only and in case of errors it is hidden until runtime.

dynamic was introduced as part of the DLR (Dynamic Language Runtime)in .Net.

Example:
dynamic d = new MYCLASS();
d.InexistingMethod();

Eventhough the method "InexistingMethod" is not there - it will GET compiled and thrown exception in runtime.

Use Strategy Pattern.
Explanation: Each GUN having different performance and GRAPHICS.
So this can be accomodated in the algorithm.

Code verification ensure that proper code EXECUTION and TYPE safety while the code RUNS. It does not allow to perform illegal operation such as INVALID MEMORY location.

Strong name helps GAC(GLOBAL ASSEMBLY cache) to differentiate between two versions.It is only needed when we deploy the assembly with GAC. It USES public KEY cryptocrophy to ENSURE that no one spoof it.

During development process we have to SIGN STRONG name with our application. But it is not GOOD practice in the SECURITY point of view. For that, we can sign it LATER. It is called delay signing.

JIT stands for Just-in-time compiler.It is a part of the runtime EXECUTION ENVIRONMENT. It compiles the INTERMEDIATE language and execute them. There are three types of JIT. They are,
1. Pre-JIT : compiles complete source code into native code in a single compilation cycle. This is done by at the time of deployment of the APPLICATION.
2. Econo-JIT : compiles only those methods that they are called at runtime. However, These compiled methods are removed when they are not REQUIRED.
3. Normal-JIT : compiles only those methods that they are called at runtime. These methods are compiled the first time they are called and then they are stored in cache. When the same methods are called again, the compiled code from cache is used for execution.

DCOM is a distributed extension of COM. It DIFFERS from COM in that it allows for creating objects distributed across a network, a PROTOCOL for INVOKING that object's methods, and secure to the object. DCOM provides a WRAPPER around COM, hence it is a backward compatible extension.

Multi-threading FORMS SUBSET of multi-tasking instead of having to switch between programs this feature switches between different parts of the same PROGRAM. For example, we can write in WORD and at the same TIME word is doing a spell check in background.

The Windows operating system does not provide support for running a CLR application. That support is provided by a CLR host. A CLR host is an application that is responsible for loading the CLR into a process, CREATING application domains within the process, and executing user code within the application domains. Examples of hosts that ship with the .NET Framework include:

ASP.NET. An ISAPI filter that ships with ASP.NET loads the CLR and does the initialization necessary to HANDLE WEB requests.

Internet Explorer. A MIME filter hooks into Internet Explorer versions 5.01 and HIGHER to execute managed controls referenced from HTML pages.

Shell Executables. When a managed application is LAUNCHED from a shell, a small piece of unmanaged code loads the CLR and transitions control of the application to the CLR.
