Devexpress XAF Blazor - Hangfire Module Implement Hangfire Startup Problem

[OgurSeren]

Hi,

Problem -1 :

We want to use JobScheduler.Hangfire module in Devexpress XAF Blazor project. We need to add the following lines in the Startup.cs file for it to work.

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

However, when I add them and open the Model.xafml file, I get the following error:

Model Editor failed to load.

Analyze the ModelEditorServerNETCore and ModelEditorClientNETCore log files in the %USERPROFILE%\AppData\Roaming\eXpressAppFramework\ folder OR send the archived folder to DevExpress Support.

For more information on how to collect this diagnostic information, refer to https://www.devexpress.com/go/XAF_ModelEditor_Troubleshooting.aspx

Could not load file or assembly 'Hangfire.Core, Version=1.7.24.0, Culture=neutral, PublicKeyToken=c52ffed5d5ff0958'. A strongly-named assembly is required. (0x80131044)

When I delete the "[assembly: HostingStartup(typeof(HangfireStartup))]"line in the Startup.cs file, the Model opens, but this time the project does not work and gets an error.

Problem -2

Although the model is not opened, Hangfire-related menus appear when I run my project. When I say new Job, unfortunately the Job definitions that I define as JobProvider do not appear in the lookups.

Expected Behavior -1 When I add the Hangfire module, model.xafml files open without problems Expected Behavior -2 The methods that I defined as Job Provider can be displayed on the Job definition screen.

until addressed u either need to use the standalone ModelEditor or the XpandModelEditor in VS2019 or XpandModelEditor in Rider

or if this really urgent to u consider prioritization of the case and a fix that fore sure will work at least in your solution by sponosring the project https://github.com/sponsors/apobekiaris

this is a known issue that some times the script fail to sing hangfire, these scripts are distributed with nuget and for some reason failed to run.

You can either sing the Hangfire assemblies manually in the nuget folder or try to run the scripts manully

again if you can correct the issue your self a PR is accepted.

Finally this is a problem raise from VS designers and the native Model Editor which I recommend to avoid. You can use either the XpandModelEditor integration or the standalond Xaf model editor and this problem will not appear
