Basics of .Net 


What is .NET?
.NET is a environment for software development. It is similar to other software development framework LIKE J2EE etc in that it provides a set of run time containers/capabilities, and a rich set of pre-built functionality in the form of class libraries and APIs.
The .NET Framework is used for building, deploying, and running Web Services and other applications.
The IDE provided by Microsoft is Visual Studio.
 It consists of three main parts: 
the Common Language Runtime, 
the Framework classes, and 
ASP.NET.

How is .NET able to support multiple languages? 
 In .NET, code is compiled to Microsoft Intermediate Language (MSIL). This is called as Managed Code. This Managed code is run in .NET environment. So after compilation to this IL the language is not a barrier. A code can call or use a function written in another language. 


What are the major components of .Net?
The major components of .Net framework are
  • CLR (Common language run-time), 
  • .Net Class library, Application domain,
  • CTS (Common Type System), 
  • .Net framework, Profiling, etc.
CLR provides building blocks for a wide variety of applications. The class library consists of a set of classes that are used to access the common functionality. The functionality can be shared among different applications.
For 

How many languages .NET is supporting now? 
When .NET was introduced it came with several languages. VB.NET, C#, COBOL and Perl, etc. The site DotNet Languages.Net says 44 languages are supported.

What is ADO .NET? 
ADO.NET is stateless mechanism. I can treat the ADO.Net as a separate in-memory database where in we can use relationships between the tables and select insert and updates to the database. We can update the actual database as a batch.

What is V C#.NET? 
Visual C# (pronounced C sharp) is designed to be a fast and easy way to create .NET applications, including Web services and ASP.NET Web applications. 
C# is a simple, elegant, type-safe, object-oriented language recently developed by Microsoft for building a wide range of applications.
Visual C# provides prototypes of some common project type which includes:

  • • Windows Application.
  • • Class Library.
  • • Windows Control Library.
  • • ASP.NET Web Application.
  • • ASP.NET Web Service.
  • • Web Control Library.
  • • Console Application.
  • • Windows Service.

Interaction with UI from windows service

I nteract ion with UI from windows service Introduction Windows service has no UI and it has never been easy to prompt users with some notifications from windows service. To interact with UI from windows service, we used to opt, allow service to interact with desktop and by launching another process from the windows service. But it is not expected to work with windows vista and upwards. So now the question is how to implement this in newer versions of windows i.e. windows 8, windows 10 etc. Here is the answer: Display a dialog box in the user's session using the  WTSSendMessage function. It can be used to display messages from windows service on all supported windows operating systems. WTSSendMessage Displays a message box on the client desktop of a specified Remote Desktop Services session. Syntax BOOL WTSSendMessageA(   IN HANDLE hServer,   IN DWORD   SessionId,   LPSTR      pTitle,   IN DWORD ...

.Net Basic terminology 1  What is the CLR? CLR: Common Language Run-time. The  Common Language Run-time ,  the virtual machine component of Microsoft's .NET framework, manages the execution of .NET programs. A process known as just-in-time compilation converts compiled code into machine instructions which the computer's CPU then executes.[1] The CLR provides additional services including  Object-oriented programming model (inheritance, polymorphism, exception handling, garbage collection) Security model Type system All .NET base classes Many .NET framework classes Development, debugging, and profiling tools Execution and code management IL-to-native translators and optimizers  All versions of the .NET framework include CLR. 2 What is the CTS? CTS: Common Type System.  This is the range of types that .NET run-time understands, and .NET applications can use. However not all .NET languages wil...
