Assemblies

Application with two versions of an assembly.

• Application's components:
  • theApp.dll - an assembly
    • value of AssemblyTitle attribute set to "theAppTitle"
    • version numbers set to:
      • 1.0 for the theApp.dll file residing in application's directory
      • 2.0 for the theApp.dll file in Global Assembly Cache (GAC)
    • non-static method GetHello() returning text:
      "Hello from <AssemblyTitle> <AssemblyVersion>" (<Assembly...> means the value of specified attribute)
  • theApp.exe - application for Windows
    • menu:
      • "Version 1.0" - calls GetHello() from 1.0 version of the assembly and displays returned value
      • "Version 2.0" - as above, for 2.0 version of the assembly
• Create an installer named theApp.msi, which installs the following elements:
  • theApp.exe into application's directory
  • 1.0 version of theApp.dll into application's directory
  • 2.0 version of theApp.dll into Global Assembly Cache (GAC)
  • shortcut to file theApp.exe placed on the desktop
• Important requirements:
  • versions 1.0 and 2.0 of theApp.dll should differ only in value of AssemblyVersion attribute
  • the application should dynamically check if version 2.0 of theApp.dll is installed in GAC; if not, it should display a message box
