  • 0

Using import aliasing in one file/class, we can reference class library namespaces by assigning our own custom alias like this:

' VB
Imports Db = Company.Lib.Data.Objects 

// C#
using Db = Company.Lib.Data.Objects;

And then we are able to reference the classes inside of Company.Lib.Data.Objects by using the Db alias that we assigned.

Is it possible to do this at the global level so that the alias is applied to the entire solution instead of just one file/class?

Currently, we are working with web applications, so I was hoping we could add something to web.config, but I am also interested in whether or not this is possible with windows forms, console apps, and/or class libraries.

    Yes this is a supported scenario in VB.Net projects. The way to do this is the following

    • Right Click on the project in Solution Explorer and select Properties
    • Go to the References tab
    • In the “Imported Namespaces” field type “Db=Company.Lib.Data.Objects”
    • Hit “Add User Import”

    This will set up the alias for all files in the project.

    This however does not work in C# projects. C# as a language doesn’t have the concept of a global using/import. Instead it only supports them at the file level.
