There are three types of generations in garbage collector. [B]Generation 0[/B] – This identifies a newly created object that has been never marked for collection. [B]Generation 1[/B] – This identifies an object which has been marked as collection but not removed. [B]Generation 2[/B] – This identifies an object that has survived more than one sweep of the Garbage collector.

INTERNAL keyword is one of the access specifier which will be visible in a given assembly i.e. in a DLL file. This forms a single binary component and it is visible throughout the assembly.

We have 3 types. [B]Pre-JIT[/B] – Compiles at the time of deployment of an application [B]Econo-JIT[/B] – Compiles called methods at runtime [B]Normal JIT[/B] – Compiles called methods at runtime and they get compiled first time when called

VB.NET is not Backward Compatible. VB was Backward Compatible but VB.NET was developed in such a way that it wont perform Backward Compatible.

The program is finding the elements within the given a range 2,10 exclusive which are 2,3,4,5,10. Then performing a summation on these numbers which is 24.

Two types of memories are there in .net stack memory and heap memory. [B]Stack Memory[/B] – Its a kind of Static Memory which set aside as scratch space for a thread of execution. Stack reserves in LIFO(Last In First Out) [B]Heap Memory[/B] – Its a kind of Dynamic memory and there’s no enforced pattern to the allocation and deallocation of blocks from the heap. To allocate memory on the heap, you must use malloc() or calloc()

Session will be created based on individual users. [B]Session Cookies[/B] are one which created at the time of User logged into our application. This Cookies contains all the details about the users and their activities in that particular session. The Session Cookies will get expired when the user Logoff. Each user will get Unique Session Cookies.

Below are the major build in objects in ASP.NET: [B] Application [/B] – It stores the information related to the entire application. So it is not specific to users. It was complete application oriented. [B]Request[/B] – It describes the methods, properties, and collections of the object that stores information related to the HTTP request [B]Response [/B] – Based on the Request the answer we got from the server is called response. [B]Server [/B] – Server is the Physical system, With these methods you can execute code, get error conditions, encode text strings, create objects for use by the Web page, and map physical paths. [B]Session [/B] – Session will store the user details and values and sent across with request and get response. [B]Context [/B] – Provides access to the entire current context (including the request object). [B]Trace [/B] – Provides a way to display both system and custom trace diagnostic messages in the HTTP page output

It caches the portion of the page generated by the request. For that, we can create user controls. For Example, Consider that you have web page which has many panels with details and Datagrid with details. But you want to take value from only one Panel and sent it across the server. In that scenario you can use Fragment Caching. How to use Fragment Caching Check below link of our site: [LINK]http://www.dotnetfunda.com/articles/show/1484/how-to-implement-fragment-caching-in-aspnet[/LINK]

[B]In-Process [/B] stores the session in memory on the web server. [B]Out-of-Process[/B] Session state management stores data in an external server. The external server may be either a SQL Server or a State Server. All objects stored in session are required to be serializable for Out-of-Process state management.

Delegates are reference types. Delegates are object oriented. Delegates are type-safe. Delegates provides wrappers for function pointers – .Net delegates are more than just type-safe function pointers. Unlike the function pointers. – A delegate is a type that safely encapsulates a method, similar to a function pointer in C and C++. Unlike C function pointers, delegates are object-oriented, type safe, and secure. The type of a delegate is defined by the name of the delegate.

Class Declaration in implementing delegates is important. Delegates types are declared with the delegate keyword. They can appear either on their own or nested within a class Example: [CODE]namespace DelegateTest { public delegate string FirstDelegateTest (int x); public class Sample { public delegate void SecondDelegateTest (char a, char b); } }[/CODE]

The Static function will be used to the keyword ref. A ref parameter is passed as a reference, not a value. This means you can assign the parameter in the called method and have it also be assigned at the calling site. So the Static function will take this reference value.
