Create an XAF project using the wizard in VS (XPO, Blazor)
Add Xpand nuget packages to project, (Xpand.XAF.Web.All, Xpand.XAF.Core.All, System.Interactive)

Configure Startup.cs:

[assembly: HostingStartup(typeof(Xpand.Extensions.Blazor.HostingStartup))]
[assembly: HostingStartup(typeof(Xpand.XAF.Modules.Blazor.BlazorStartup))]

Register an Xpand module e.g. in BlazorModule.cs


using System.ComponentModel;
using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Updating;

namespace XafXpand2224.Blazor.Server;

[ToolboxItemFilter("Xaf.Platform.Blazor")] // For more typical usage scenarios, be sure to check out https://docs.devexpress.com/eXpressAppFramework/DevExpress.ExpressApp.ModuleBase. public sealed class XafXpand2224BlazorModule : ModuleBase { public XafXpand2224BlazorModule() { RequiredModuleTypes.Add(typeof(Xpand.XAF.Modules.Reactive.ReactiveModule)); RequiredModuleTypes.Add(typeof(Xpand.XAF.Modules.RefreshView.RefreshViewModule)); } public override IEnumerable GetModuleUpdaters(IObjectSpace objectSpace, Version versionFromDB) { return ModuleUpdater.EmptyModuleUpdaters; } public override void Setup(XafApplication application) { base.Setup(application); } }


5. Run Web project, initially the navigation screen is shown and then crashes after a few seconds.

The pre-release 4.222.2.0 in the Reactive.XAF lab branch includes commits that relate to this task:

Fix wrong namespaces #978 #982

To minimize version conflicts we recommend that you use the Xpand.XAF.Core.All, Xpand.XAF.Win.All, Xpand.XAF.Web.All packages. Doing so, all packages will be at your disposal and .NET will add a dependecy only to those packages that you actually use and not to all (see the Modules installation-registrations youtube video).

Released packages:

Please update the related Nuget packages and test if issues is addressed. These are nightly nuget packages available only from our NugetServer.

If you do not use these packages directly but through a module of the main eXpandFramework project, please wait for the bot to notify you again when integration is finished or update the related packages manually.

Thanks a lot for your contribution.
