Answers8). what are the consideration in deciding to use .NET Remoting or ASP.NET Web Services?
- hr@percosoft.com February 10, 2022 in India
Remoting is a more efficient communication exchange when you can control both ends of the application involved in the communication process. Web Services provide an open-protocol-based exchange of information. Web Services are best when you need to communicate with an external organization or another (non-.NET) technology.| Report Duplicate | Flag | PURGE

Answers7). what is "Common Language Runtime" (CLR)?
- hr@percosoft.com February 10, 2022 in India
CLR is .NET equivalent of Java Virtual Machine (JVM). It is the runtime that converts a MSIL code into the host machine language code, which is then executed appropriately. The CLR is the execution engine for .NET Framework applications. It provides a number of services, including:
- Code management (loading and execution).
- Application memory isolation.
- Verification of type safety.
- Conversion of IL to native code.
- Access to metadata (enhanced type information).
- Managing memory for managed objects.
- Enforcement of code access security.
- Exception handling, including cross-language exceptions.
- Inter operation between managed code, COM objects, and per-existing DLL's (unmanaged code and data)
- Automation of object layout.
- Support for developer services (profiling, debugging, and so on).| Report Duplicate | Flag | PURGE

Answers5). what is "Common Type System" (CTS)?
- hr@percosoft.com February 10, 2022 in India
CTS define all of the basic types that can be used in the .NET Framework and the operations performed on those type. All this time we have been talking about language interoperability, and .NET Class Framework. None of this is possible without all the language sharing the same data types. What this means is that an int should mean the same in VB, VC++, C# and all other .NET compliant languages. This is achieved through introduction of Common Type System (CTS).| Report Duplicate | Flag | PURGE

Answers4). what is the difference between "using System. Data;" and directly adding the reference from "Add References Dialog Box"?
- hr@percosoft.com February 10, 2022 in India
When u compiles a program using command line, u add the references using /r switch. When you compile a program using Visual Studio, it adds those references to our assembly, which are added using "Add Reference" dialog box. While "using" statement facilitates us to use classes without using their fully qualified names.
For example: if u have added a reference to "System.Data.SqlClient" using "Add Reference" dialog box then u can use SqlConnection class like this:
System.Data.SqlClient.SqlConnection
But if u add a "using System.Data.SqlClient" statement at the start of our code then u can directly use SqlConnection class. On the other hand if u add a reference using "using System.Data.SqlClient" statement, but don't add it using "Add Reference" dialog box, Visual Studio will give error message while we compile the program.| Report Duplicate | Flag | PURGE

Answers2). what is inheritance hierarchy?
- hr@percosoft.com February 10, 2022 in India
The class which derives functionality from a base class is called a derived class. A derived class can also act as a base class for another class. Thus it is possible to create a tree-like structure that illustrates the relationship between all related classes. This structure is known as the inheritance hierarchy.| Report Duplicate | Flag | PURGE

Answers1). what is .NET?
- hr@percosoft.com February 10, 2022 in India
.NET is essentially a framework for software development. It is similar in nature to any other software development framework (J2EE etc) in that it provides a set of runtime containers/capabilities, and a rich set of pre-built functionality in the form of class libraries and APIs
The .NET Framework is an environment for building, deploying, and running Web Services and other applications. It consists of three main parts: the Common Language Runtime, the Framework classes, and ASP.NET.| Report Duplicate | Flag | PURGE
