How do I reference an assembly that is in the GAC?

H Since the .NET tab in the "Add Reference ..." dialog does 开发者_Python百科not show the assemblies form the GAC what is the common best practise to add a reference to an assembly that was installed in GAC to my visual studio project?

How can I reference a dll in the GAC from Visual Studio?

"Add Reference..." dialog modifies your project file (for example .csproj for C#). It is simple msbuild file. To add reference to your project you should modify node: Reference

<Reference Include="System.Data.Services">
  <RequiredTargetFramework>3.5</RequiredTargetFramework>
</Reference>
