InvalidOperationException WarmUpApplication Backend Web API Service

[TheGermanNiko]

Hi we recently startet upgrading our Application to net6, as a part of it i tried to include the Web API from DevExpress to it. Everytime i try to start the Web API it throws an Exception.

System.InvalidOperationException: Exception occurs while initializing the 'Xpand.XAF.Modules.ModelMapper.ModelMapperModule' module: DevExpress.ExpressApp.AspNetCore.WebApi.Core.Internal.WarmUpApplication.

I created a simple Demo Project containing all refrences as they are used in our Application. Any ideas what causes that exception?

Create the Application and attempt to start the Web API.

I did not test your sample the cause I see you use ModelMapperModule which does not support the Blazor or WebAPI projects
