Add the Office Module to Your Application

Install the appropriate platform-specific NuGet package and use one of the following techniques to add the Office Module:

• You can add modules to your application when you use the Solution Wizard to create a new XAF solution. Select modules in the Choose Additional Modules step.

• In .NET applications, you can call the AddOffice(IModuleBuilder<IBlazorApplicationBuilder>, Action<OfficeOptions>) / AddOffice(IModuleBuilder<IWinApplicationBuilder>, Action<OfficeOptions>) method in your ASP.NET Core Blazor / WinForms application builder.

• If you do not use an application builder, you can add these Modules to the ModuleBase.RequiredModuleTypes collection of the platform-specific Module.
• In .NET Framework applications, you can also use the Module Designer and Application Designer to add a module to your project.

The following additional steps may be required:

ASP.NET Core Blazor Application Without Application Builder

Navigate to the MySolution.Blazor.Server\Startup.cs file and call the AddOffice method in the Startup.ConfigureServices method to register the Office Module services in IServiceCollection:

using DevExpress.ExpressApp.Office.Blazor;
// ...
public class Startup {
    // ...
    public void ConfigureServices(IServiceCollection services){
        //...
        services.AddOffice();
    }
    // ...
}
