23. Requirement of Application or OS services which is required to your application framework (CLR) provide to your application. CLR is live or run time environment when you run your application, CLR communicate with your OS..NET Framework Introduction Prepared By : Syed Noman Ali

24. Strong Reason For Developing.NET, Application which is created in C++,Vb6 programmer can’t use application of C++. If an Application is Written in C++ in VB you have to write this application again. Because Tool Change, Language Change, Input Change, Output change..NET Framework Introduction Prepared By : Syed Noman Ali

25. C++ Developer Says he/she create strong application he/she use pointers etc. VB6 programmer says he/she creates application rapidly. Now like a wheel we create and application in C++ and we can use in VB6 etc..NET Framework Introduction Prepared By : Syed Noman Ali

26. Now you have visual studio single integrated development environment, one tool in which you can create application in C++ as Well a VB6 etc. But Before.NET tool change language change, input change, output change, Compiler different..NET Framework Introduction Prepared By : Syed Noman Ali

27. First your learn Tool then language syntax etc. Now Tool same, IDE same, Input (Libraries ) same, out put same. 30 + languages run on single IDE.NET Framework Introduction Prepared By : Syed Noman Ali

28. A tool which facilitate all developers. C# developer using these tool as well as VB, C++ etc. In a single tool VB6 application is compiling, C# sharp compiling, C++ compiling, not possible to think, but Microsoft does..NET Framework Introduction Prepared By : Syed Noman Ali

29. VB.Net compiler is vbc, C# compiler is csc. All language running on a single platform. Behind the scene when you compile your application of VB vbc compiler use, C# application csc compiler use on a single IDE..NET Framework Introduction Prepared By : Syed Noman Ali

30. How its possible application written in C++ or VB can use in C#. When you compile your application of C#, C# compiler csc produce output in MSIL which is another low level language. Also when you compile your VB application, vb compiler vsc compiler produce out in MSIL..NET Framework Introduction Prepared By : Syed Noman Ali

31. C# application out is in MSIL and VB application out also in MSIL. Out which is produce by vsc VB.NET in the form of MSIL, VB.NET compiler can consume this out put. You can write library, now you can use this library through add reference on 1000 places now your compiler is also producer as well as consumer..NET Framework Introduction Prepared By : Syed Noman Ali

32. Suppose you write a function after compile make it DLL, now you can use any where. VB.NET compiler is producing and consuming MSIL, C# compiler consuming and producing MSIL, SO now C# compiler can understand output produced by VB.NET..NET Framework Introduction Prepared By : Syed Noman Ali

33. Because when both C# and VB.NET understands MSIL so they can communicate..NET Framework Introduction Prepared By : Syed Noman Ali

34. You compile your application MSIL or exe produce. When your double click or run your application CLR again Compile your application using JIT and produce native according to your OS. IF Your Os is windows 7 then it will generate native code according to windows7..NET Framework Introduction Prepared By : Syed Noman Ali

35. Before framework when you compile your code on 32 bit system, so 32 can use your code only. But Now your application can run after 10 years because of forward compatibility. Except one platform 16bit. Now Your application will be platform independent but for Windows..NET Framework Introduction Prepared By : Syed Noman Ali

36. When JIT compile MSIL this is double compilation. When you compile one language and in the result another language produce is cross compilation. Double compilation.NET framework does and Cross compilation you have to do..NET Framework Introduction Prepared By : Syed Noman Ali
