HTML, CSS, Java Script HTML – “hypertext markup language” standard format of writing a webpage. CSS – “cascading style sheet”. Describes the tags. It controls layout of multiple Web pages at once. Java Script – performs an event. Makes a page alive. Designing languages
PHP, ASP, ASP.NET PHP – “hypertext preprocessor”. ASP – “active server script” ASP.NET – built on CLR. Therefore supports.NET languages. Server languages
Silverlight and Flash In order to run an application made by these, you need a plug-in for the web browser Microsoft Silverlight – supports VB, C#. Adobe Flash – supports Action Script. Extensive languages
XAML XAML – “Extensible Application Markup Language”. It is extended XML developed by Microsoft. One usage is to write a layout for applications. XML – similar to html, but does not require specific tags; you define them. Application design
Windows Applications C/C++ Microsoft.NET Framework work – consist of CLR and a class library – Visual C# – Visual Basic – Visual F#
C/C++ Produces unmanaged code (native CPU code) C was develop 1979, and has been used since then.
Microsoft.NET Framework All languages that target CLR may use almost all features in.NET Class Library. A language that targets CLR may only use a subset of the features that are available in CLR. All applications are usually managed. They contain metadata, etc. When you run an application of that kind, the JIT compiler compiles the IL code.
CLR – common language runtime
