2 Maual Microsoft.NET 2.0 Applicatio Developmet (70-536) Overview of ew features, ehacemets, ad capabilities of the.net Framework Microsoft.NET Framework 2.0 Certificatio Path This Maual will help prepare you for the certificatio exam for : TS: Microsoft.NET Framework 2.0 Applicatio Developmet Foudatio. This exam is oe of the examiatios required for oe of the followig three Microsoft Certified Techology Specialist (MCTS) certificatios: Microsoft Certified Techology Specialist:.NET Framework 2.0 Web Applicatios Microsoft Certified Techology Specialist:.NET Framework 2.0 Widows Applicatios Microsoft Certified Techology Specialist:.NET Framework 2.0 Distributed Applicatios Microsoft Techology Specialists are capable of buildig, implemetig, troubleshootig, ad debuggig applicatios usig Microsoft techologies. The above certificatios require that a cadidate pass the exam ad oe additioal exam specific to each certificatio path. The certificatio path for all three optios is follows: MCTS Certificatio Path Optios LearSmart Cloud Classroom: Video Traiig s Mauals

3 Maual Microsoft.NET 2.0 Applicatio Developmet (70-536) Cadidates for the exam ca select the programmig laguage i which all code examples will appear. Whe the exam begis, they must select from oe of the followig: Microsoft Visual Basic 2005 Microsoft Visual C# 2005 Microsoft Visual C The exam cosists of 150 questios that measure cadidates kowledge of the fudametals of the.net Framework 2.0. It covers ew features ad ehacemets i the followig areas, specifically, the ehaced capabilities of the amespaces. After achievig a Microsoft Certified Techology Specialist (MCTS) certificatio, cadidates ca ehace their certificatio level by becomig a Microsoft Certified Professioal Developer (MCPD). The MCPD certificatio is targeted to a cadidate s specific techical expertise. The three MCPD certificatios are: Microsoft Certified Professioal Developer: Web Applicatios Developer Microsoft Certified Professioal Developer: Widows Applicatios Developer Microsoft Certified Professioal Developer: Eterprise Applicatios Developer Each of the above certificatios requires a cadidate to pass oe additioal exam specific to a certificatio path (the MCPD: Eterprise Applicatios Developer requires all three MCTS exams i additio to the MCPD exam). The certificatio path for all three optios is displayed below: LearSmart Cloud Classroom: Video Traiig s Mauals

5 Maual Microsoft.NET 2.0 Applicatio Developmet (70-536) Upgrade Certificatio Path Optios 1.2 Fudametals of the.net Framework This maual assumes that you are familiar with the.net Framework ad have bee developig applicatios (Widows Forms/Widows GUI Applicatios, ASP.NET Web applicatios, Mobile applicatios, Widows Services, Cosole Applicatios, XML Web Services, etc.). The : TS: Microsoft.NET Framework 2.0 Applicatio Developmet Foudatio primarily covers ehacemets made to the.net Framework, specific to versio 2.0, but we will briefly review the.net Framework. For more detailed iformatio o the.net Framework ad iformatio o each of the examiatio optios available, refer to the Itroductio. The.NET Framework is a laguage-eutral compoet library ad executio eviromet that provides the ifrastructure for buildig applicatios usig.net. Applicatio developers ca build powerful, eterprise, itegrated applicatios regardless of platform or laguage. The.NET Framework 2.0 does ot itroduce a ew developmet framework or paradigm, implemetatio model, or scriptig model from the previous release of.net Framework 1.0 or.net Framework 1.1 (the.net Framework Release 1.0 was iitially released i Jauary of 2002). But because it is more tha a icremetal release, it itroduces some sigificat ehacemets to the.net Framework. The.NET framework is a object-orieted hierarchy of classes that are ubiquitous to all Microsoft Widows operatig systems, regardless of whether the user is developig applicatios for Widows Forms, Web applicatios, mobile applicatios, services, or ay other task.

6 Maual Microsoft.NET 2.0 Applicatio Developmet (70-536) a class, ad defies the class properties, evets, ad methods that build the fuctioality of the applicatio. With.NET, these classes support object-orieted features such as polymorphism, iheritace ad ecapsulatio. For example, whe executig a ASP.NET applicatio, the ASP.NET rutime egie will trasform the source code the.aspx page ito a istace of a.net framework class that iherits from the Page base class. This fudametal cocept is why this exam ( : TS: Microsoft.NET Framework 2.0 Applicatio Developmet Foudatio) must be passed i tadem with ay of three other exams to ear a Microsoft Certified Techology Specialist certificatio (with a focus o either.net Framework 2.0 Web Applicatios,.NET Framework 2.0 Widows Applicatios, or.net Framework 2.0 Distributed Applicatios). The.NET Framework has two mai compoets: The commo laguage rutime (CLR) The.NET Framework class library The commo laguage rutime (CLR) is at the foudatio of the.net Framework. The CLR provides a rutime eviromet ad ru-time services for.net applicatios ad is resposible for code maagemet, access security, laguage iterpretatio, memory maagemet, thread maagemet, process maagemet, compilatio ad code accuracy, strict type ad code verificatio (the commo type system of CTS) to esure that all maaged code is self-describig. Code maagemet is a importat priciple i the.net Framework. Code targetig the rutime is maaged code (custom object libraries, class libraries), while code ot targetig the rutime is umaaged code (Iteret Iformatio Services, ASP.NET web applicatios). The CLR also provides a maagemet eviromet that automatically provides commo services (garbage collectio ad security). I additio, ASP.NET provides the eviromet to icorporate both maaged ad umaaged features, such as a umaaged compoet or applicatio such as Iteret Explorer with a embedded maaged compoet or Widows Forms cotrol. As a applicatio developer or system admiistrator, you are cocered with productivity, reliability ad performace. Because the rutime automatically hadles object layout as well as maaged refereces to objects i memory, they are automatically released whe o loger beig used. This feature helps elimiate memory leaks ad ivalid object memory refereces. Fially, the Just I Time complier (JIT) allows for maaged code to ru i the system s ative machie laguage. Also, because the CLR supports developmet i multiple developmet laguages, applicatio developers ca script i their laguage of choice while still accessig a commo rutime ad class library. Fially, the CLR also provides other fudametal services which are outside the scope of this book. However, this book will focus o the.net Framework class library, specifically, o the features, ehacemets, ad capabilities of the class libraries available i the.net Framework 2.0. Microsoft defies the.net Framework as: a comprehesive, object-orieted collectio of reusable types that you ca use to develop applicatios ragig from traditioal commad-lie or graphical user iterface (GUI) applicatios to applicatios based o the latest iovatios provided by ASP.NET, such as Web Forms ad XML Web services. I short, the.net Framework cotais the object-orieted, hierarchical, extesible classes, iterfaces, ad value types that provide the framework to build.net applicatios, compoets ad cotrols. They provide the stadard fuctioality that allows developers to utilize strig maipulatio, security maagemet, etwork commuicatios, thread maagemet, iput/output cotrols ad user iterface desig features. The.NET Framework provides class libraries (APIs) that replace the libraries ad frameworks previously used by applicatio developers based upo their programmig laguage (Microsoft Foudatio Classes for C++ developers, Visual Basic rutime for VB developers, etc.). The.NET Framework simplifies those issues by providig a commo set of APIs for all the supported programmig laguages (at the time of this writig, more tha 25 laguages are supported). The.NET Framework supports cross-laguage iheritace (you ca iherit classes across laguage boudaries), error hadlig ad debuggig. A class writte i oe LearSmart Cloud Classroom: Video Traiig s Mauals
