- Configuring Barcode Professional for using it in Microsoft Expression Web. In order to enable design-time support for Barcode Professional in Microsoft Expression Web (This step must be performed only once on your machine), the Neodynamic.WebControls.BarcodeProfessional.dll file must be registered to the GAC (Global Assembly Cache).

Registering Barcode Professional file to the GAC
Open two instances of Windows Explorer. In the first instance go to the folder where you installed Barcode Professional for ASP.NET and in the second instance go to the C:\Windows\assembly folder. After that, drag & drop the Neodynamic.WebControls.BarcodeProfessional.dll file from [InstallDir]\Redistributable\For NET 2.0 folder to the C:\Windows\assembly folder as is shown in the following figure.
