New Code Editor and MEF

New Code Editor and MEF

Visual Studio (VS) 2010 introduces a new Editor composed of extensible objects using the Microsoft Extensibility Framework (MEF). It is built on WPF to provide a 1st-class graphics engine with APIs written & designed for the latest version of .NET. This time around we are documenting APIs as part of our development process to improve documentation and help. We are also focused on delivering improved data structures and algorithms. Immutable Text Snapshots allow access to stable version of text buffer from any thread.

The new editor represents one of the first Visual Studio components to move to a managed code, MEF architecture. Other components moving to this architecture in VS2010 include the Visual Studio Languages, Web Tools, the Debugger, the new C++ project system, DSL Tools, and SharePoint Designer. Each of these components are using or offering MEF extension points. The editor represents Visual Studio’s largest investment in a MEF architecture. These moves to managed code and MEF will be followed by others as much of Visual Studio moves to this new architectural foundation in following versions.

Shims will provide 80+ percent compatibility to minimize the work for partners migrating code to the new editor. However where possible partners should update their code to use the new managed editor interfaces for the VS2010 editor. This will result in better performance and simpler code that is easier to understand and maintain. It will also migrate to the follow-on version of Visual Studio with less problems because we will be deprecating the shims in the next version after VS2010.

Partners should also consider using MEF for their own extensibility requirements in their own .NET based applications, that is, other applications have nothing to do with Visual Studio.

Can I use typedefs in C#?

Can I use typedefs in C#?

 

C# doesn't have typedef but It does have it in the form of using. But this is limited in terms of usage and functionality

 

Ex.

 

using EmpList = System.Collections.Generic.List<MyNameSpace.Employee>;

using NUMBER = System.Int32;

 namespace MyNameSpace

{

    public class Employee

    {

    }

     public class Class1

    {

        public Class1()

        {

            EmpList empList = new EmpList();

            NUMBER num = 8;

        }

    }
}

What standard types does C# use?


C# supports a very similar range of basic types to C++, including int, long, float, double, char, string, arrays, structs and classes. However, don’t assume too much. The names may be familiar, but many of the details are different. For example, a long is 64 bits in C#, whereas in C++ the size of a long depends on the platform (typically 32 bits on a 32-bit platform, 64 bits on a 64-bit platform). Also classes and structs are almost the same in C++ - this is not true for C#. Finally, chars and strings in .NET are 16-bit (Unicode/UTF-16), not 8-bit like C++.

Are C# references the same as C++ references?

There is one significant difference between C++ and C# references, C# references can be null. Therefore, a C# reference may not point to a valid object. A C# reference is a bit like a C++ pointer in this regard.

Does C# replace C++?

Does C# replace C++?

C# never replaces C++
C# is not understood by the machine (C# is compiled by .NET CLR and translated into Executable code by the machine).
C++ has the advantages of being fast and small in memory in Games Development.
Cross platform and speed restraints(Linux and MAC)

What are the fundamental differences between value types and reference types?

Value Types

The value of value types are stored on the managed stack, and can be used directly. This means that the value is stored, and not a reference to the value. This also means that each value type has its own copy of the data. Reference Types on the other hand has a reference to the data, and several variables can reference the same data.

Reference Types

In contrast to value types, the value of a reference types is allocated on the heap. Another name for a reference type, that you might be more familiar with, is an object. Reference types stores the reference to the data, unlike value types, that stores the value

How do I develop C# apps?

C# is Object-Oriented and Component oriented programming language, it is developed by Microsoft.

We can develop C# application using the Visual Studio 2003 or latter version.

We can download latest Visual studio version as a free at following location.

Microsoft provides the .NET SDK also it is complete free.

What is C#?

Have you heard of C# (pronounced See-Sharp)? It would not be unusual if you didn't know a lot about the language. Released to the public in June 2000, C# has not been around for very long.

C# is a new language created by Microsoft and submitted to the ECMA for standardization. This new language was created by a team of people at Microsoft led by Anders Hejlsberg . Interestingly, Hejlsberg is a Microsoft Distinguished Engineer who has created other products and languages, including Borland Turbo C++ and Borland Delphi. With C#, they focused on taking what was right about existing languages and adding improvements to make something better.

C# is a powerful and flexible programming language. Like all programming languages, it can be used to create a variety of applications. Your potential with C# is limited only by your imagination. The language does not place constraints on what you can do. C# has already been used for projects as diverse as dynamic Web sites, development tools, and even compilers.

C# was created as an object-oriented programming (OOP) language. Other programming languages include object-oriented features, but very few are fully object-oriented. In my book you can learn how C# compares to some of these other programming languages. My book also covers what it means to use an object-oriented language as well as the details of doing object-oriented programming with C#.

DOT NET FAQ's

What is a CLR?

 

Full form of CLR is Common Language Runtime and it forms the heart of the .NET framework.
All Languages have runtime and its the responsibility of the runtime to take care of the code
execution of the program. For example VC++ has MSCRT40.DLL,VB6 has MSVBVM60.DLL,
Java has Java Virtual Machine etc. Similarly .NET has CLR. Following are the responsibilities of
CLR

 

√ Garbage Collection :- CLR automatically manages memory thus eliminating
memory leaks. When objects are not referred GC automatically releases those
memories thus providing efficient memory management.

 

√ Code Access Security :- CAS grants rights to program depending on the security
configuration of the machine. Example the program has rights to edit or create
a new file but the security configuration of machine does not allow the program
to delete a file. CAS will take care that the code runs under the environment of
machines security configuration.

 

√ Code Verification :- This ensures proper code execution and type safety while
the code runs. It prevents the source code to perform illegal operation such as
accessing invalid memory locations etc.

 

√ IL( Intermediate language )-to-native translators and optimizer's :- CLR uses
JIT and compiles the IL code to machine code and then executes. CLR also
determines depending on platform what is optimized way of running the IL
code.

 

.NET FAQ's

What is a IL? Twist :- What is MSIL or CIL , What is JIT?

 

(IL)Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate Language). All .NET source code is compiled to IL. This IL is then converted to machine code at the point where the software is installed, or at run-time by a Just-In- Time (JIT) compiler.
