Question

I just started using WiX, with zero knowledge of C#/.NET

Now I’m trying to create a simple WiX extension by referring this page: WiX3 – Simple Example of Extension.

Here is steps described in that page:

• In Visual Studio, create a new C# library (.dll) project named SampleWixExtension.

• Add a reference to wix.dll to your project.

• Add a using statement that refers to the Microsoft.Tools.WindowsInstallerXml namespace.

  using Microsoft.Tools.WindowsInstallerXml;

• Make your SampleWixExtension class inherit from WixExtension.

  public class SampleWixExtension : WixExtension {}

• Add the AssemblyDefaultWixExtensionAttribute to your AssemblyInfo.cs.

  [assembly: AssemblyDefaultWixExtension(typeof(SampleWixExtension.SampleWixExtension))]

• Build the project.

However, when I finished these steps and built this project, I met following errors:

    ------ Build started: Project: SampleWixExtension, Configuration: Debug Any CPU ------
    D:\working\test\SampleWixExtension\SampleWixExtension\Properties\AssemblyInfo.cs(37,12): error CS0246: The type or namespace name 'AssemblyDefaultWixExtension' could not be found (are you missing a using directive or an assembly reference?)
    D:\working\test\SampleWixExtension\SampleWixExtension\Properties\AssemblyInfo.cs(37,12): error CS0246: The type or namespace name 'AssemblyDefaultWixExtensionAttribute' could not be found (are you missing a using directive or an assembly reference?)

    Compile complete -- 2 errors, 0 warnings

Anyone know why and how to fix it?

Btw, in the Solution Explorer I can see wix is already in References, its properties has Path of C:\Program Files (x86)\Windows Installer XML v3.5\bin\wix.dll

Answer 1

By adding

using Microsoft.Tools.WindowsInstallerXml;

into AssemblyInfo.cs, the project is now successfuly built.
