  Introducing C# VeryJava-like syntax Sophisticated OO support The .NET flagship language Based on Open Standards (ECMA/ISO) C# will be used more than C++ for .NET, but not as much as VB.NET.

  C# versus Java
• 34.
  C# versus Java C# uses native code compilation more often than Java. C# has more primitive data types than Java (enumerators, structs). C# supports full operator overloading. C# and Java handle multiple inheritance differently. C# and Java both support “delegates” in lieu of pointers. C# implements multidimensional arrays more completely than Java’s array-of-an-array.

  C# versus C++
• 36.
  C# versus C++ C# eliminates header files. C# has built-in memory management. C# nearly eliminates the need for pointers. C# is more purely object oriented with all objects and types deriving from a root Object class. The C# “switch” statement does not all fall-through.

  Visual Studio 2008A look at a Visual Studio 2008 solution Somewhat different hierarchy: Visual Studio Solution (.sln) C# Project (.csproj) VB Project (.vbproj) Etc… Solutions are like “Project Groups” except that you always have a solution to encompass even just one project.
