Define .NET Framework?

Posted By :Narayanan     Posted Date :August 31, 2011    Points :40   Category :.NET Framework 
It is an environment for developing, building, deploying and executing Desktop Applications, Web Applications and Web Services.

Which assembly is used to define the MVC framework and Why ?

  
The MVC framework is defined through System.Web.Mvc assembly.
This is because this is the only assembly which contains classes and interfaces that support the ASP.NET Model View Controller (MVC) framework for creating Web applications.

What is .NET Framework?

  
The .NET Framework has two main components: the common language runtime and the .NET Framework class library.
You can think of the runtime as an agent that manages code at execution time, providing core services such as memory management, thread management, and remoting, while also enforcing strict type safety and other forms of code accuracy that ensure security and robustness.
The class library, is a comprehensive, object-oriented collection of reusable types that you can use to develop applications ranging from traditional command-line or graphical user interface (GUI) applications to applications based on the latest innovations provided by ASP.NET, such as Web Forms and XML Web services. (More...)

What is the .NET Framework?

  
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. (More...)

Does the .NET Framework only apply to people building Web sites?

  
The .NET Framework enables you to create great Web applications. However, it can also help you build the same applications you build today. If you write any Windows software (using ATL/COM, MFC, Microsoft® Visual Basic®, or even standard Microsoft® Win32®), .NET offers many advantages to the way you currently build applications. Of course, if you do develop Web sites, then the .NET Framework has a lot to interest you-starting with ASP.NET. (More...)

What programming languages will the .NET Framework support?

  
The .NET Framework is language neutral; virtually any language can target the .NET Framework. Currently, you can build .NET programs in a number of languages, including C++, Microsoft® Visual Basic.NET, _JScript®, and Microsoft's newest language-C#. A large number of third-party languages will also be available for building .NET Framework applications. These languages include COBOL, Eiffel, Perl, Python, Smalltalk, and others. (More...)

What is the relationship between the .NET Framework and COM+ Services?

  
The .NET Framework gives you full access to COM+ services, while also making it easier to build serviced components.
.NET Framework components can be added to a COM+ application. There they can take advantage of automatic component services such as transactions, object pooling, queued components, events, and so on. (More...)

What is the relationship between the .NET Framework and DCOM?

  
DCOM is the COM infrastructure for cross-process communication. The .NET Framework supports a number of pluggable channels and formatters for cross-process communication. When making transitions between managed and unmanaged code, the .NET Framework uses the COM infrastructure, specifically, DCOM. All scenarios using COM+ services use managed-to-unmanaged transitions, and thus use DCOM by default. The .NET Framework also supports SOAP, the Simple Object Access Protocol, for cross-process communication where interoperability is critical. (More...)

Is the .NET Framework just a new name for Windows DNA?

  
No. Windows DNA is architecture for building tightly-coupled, distributed Web applications. As the needs of distributed applications changed to require more loosely-coupled principles, Microsoft evolved the architecture to .NET. The .NET Framework is a part of the .NET architecture. (More...)

What programming languages will the .NET Framework support?

  
The .NET Framework is language neutral; virtually any language can target the .NET Framework.

A large number of third-party languages will also be available for building .NET Framework applications. These languages include COBOL, Eiffel, Perl, Python, Smalltalk, and others. (More...)

Define namespace in C++ ?

  
It is a feature in c++ to minimize name collisions in the global name space. This namespace keyword assigns a distinct name to a library that allows other libraries to use the same identifier names without creating any name collisions. Furthermore, the compiler uses the namespace signature for differentiating the definitions. (More...)

Define precondition and post-condition to a member function.

  
Precondition:
A precondition is a condition that must be true on entry to a member function. A class is used correctly if preconditions are never false. An operation is not responsible for doing anything sensible if its precondition fails to hold.
For example, the interface invariants of stack class say nothing about pushing yet another element on a stack that is already full. We say that isful() is a precondition of the push operation.


Post-condition:
A post-condition is a condition that must be true on exit from a member function if the precondition was valid on entry to that function. A class is implemented correctly if post-conditions are never false.
For example, after pushing an element on the stack, we know that isempty() must necessarily hold. This is a post-condition of the push operation. (More...)

Define the "integrity rules"

  
There are two Integrity rules.
1.Entity Integrity: States that "Primary key cannot have NULL value"

2.Referential Integrity: States that "Foreign Key can be either a NULL value or should be Primary Key value of other relation. (More...)

Can I use COM objects from a .NET Framework program?

  
Yes.

Any COM component you have deployed today can be used from managed code, and in common cases the adaptation is totally automatic.
Specifically, COM components are accessed from the .NET Framework by use of a runtime callable wrapper (RCW). This wrapper turns the COM interfaces exposed by the COM component into .NET Framework-compatible interfaces. For OLE automation interfaces, the RCW can be generated automatically from a type library. For non-OLE automation interfaces, a developer may write a custom RCW and manually map the types exposed by the COM interface to .NET Framework-compatible types.
