Introduction to Visual Studio and C#

Review Questions

1. What do these acronymns mean?
   ADO.Net   ASP.Net   CLR   CLS   COM   GAC

   MSIL   PE   SNA   VES   XAML

2. Define these terms:
   solution   assembly   manifest   strong name   GAC   culture

3. What are some flags that are used with the C# command line compiler.

4. How does the .Net VES know where to find the DLL files referenced in the manifest.

5. How does the CLR know which version of a DLL to choose in the GAC out of multiple versions?
   Ans: The most recent version is chosen. If you prefer a specific version, include this .csproj file reference as a ItemGroup element:

   <Reference Include="Vehicle, Version=1.9.3.25, 
      Culture=neutral, processorArchitecture=MSIL">
      <SpecificVersion>true</SpecificVersion>
   <Reference>
   

6. What is the difference between a class and an object?

7. What are properties, methods, and events for a class?

8. Given these classes, give some possible properties, methods, and events: BasketballPlayer, Windows-style Button.

Some Features of Visual Studio and C#.NET

• Explicit design time code is shown.

• Partial Classes:
  (1) Form1.cs contains programmer written code.

  (2) Form1.Designer.cs contains code automatically generated by the Windows Form Designer.

• Operator new is used to instantiate forms and other objects.

• Event handlers are registered using delegates.

• Controls are dragged onto the Form Designer Window from the Toolbox.

• Invisible components are shown on Control Tray.

• The Menu Editor is similar to the Visual C++ Menu Editor.

• The universal datatype is object.

• Parameterized constructors are available.

• The three major "pillars" of OOP are supported:
  Data Hiding, Inheritance, Polymorphism.

• The try..catch construction is used for handling exceptions.

• Some C# constructs:
  Namespaces, Delegates, Operator Overloading,

  User Defined Casts, Multithreading.

• Intellisense:
  List Members, Quick Info, Parameter Info.

• IDE settings may be exported.

• Internationalization Capabilities:
  Cultures, XML Resource Files, Unicode Support.

Some .Net File Extensions

.Net System Datatypes
