How to always call the database updater in E1344 (for scheme changes based on tenants)

Instead of using the subdomain I refactored the application accordingly to https://github.com/DevExpress-Examples/XAF_how-to-change-connection-to-the-database-at-runtime-e1344/

I use my own service to detect the tennant instead of a drop down (works)

However, when I log out and login with a different tennant, it will fail, because the database updater is not called.

Is there any way to trigger the module updaters after each login.

It should be, because the modules can differ per tennant too.

Hello Michael,

This behavior is managed by the XafApplication.IsCompatibilityChecked property. In our example, this property stores an individual value for each connection string: BlazorApplication.cs. Please make sure your application has similar code. If this code does not work in your case, you may need to use a tenant ID instead of a connection string.
Please let me know if you need further assistance.

Hi Anatol,

I am trying to add Custom Modules to a solution, based on the tennant.
To perform that, I wrote a test in Blazor Module:

C#
[ActivatorUtilitiesConstructor]
public BlazorModule(ICurrentTennant tennant):this()
{
    this._tennant = tennant;

    if (tennant.Code.ToLower() == "test")
        this.RequiredModuleTypes.Add(typeof(TestModule));
}

public BlazorModule() : base() {
}

It seems not to work.

Hello Michael,

I created a separate ticket on your behalf: T1192806: How to use dependency injection in modules. We placed it in our processing queue and will process it shortly.
