Exception: Window already exists

[ChristianM66]

Hello, I am using DryIoC in conjunction with IServiceColleciotn in net8 and Maui.
When merging DryIoC and IServiceCollection using IContainer.Populate the following exception is thrown .

Without DryIoC and the Populate call, the exception does not occur.

Many thanks for your help

What is the exception message?

What is the exception message?
The exception message is: Window already exists.

The error occurs under net8 regardless of which versions of DryIoC and DryIoc.Microsoft.DependencyInjection are used.

ioCManager encapsulates DryIoC.IContainer and is registered in DryIoContainer itself.

DryIoC: 5.4.3
DryIoc.Microsoft.DependencyInjection: 6.2.0

Configuration:
private IocManager()
{
this.Container = new Container(_ =>
Rules.Default.WithConcreteTypeDynamicRegistrations(reuse: Reuse.Transient).
With(Made.Of(FactoryMethod.ConstructorWithResolvableArguments)).
WithFuncAndLazyWithoutRegistration().
WithTrackingDisposableTransients().
WithFactorySelector(Rules.SelectLastRegisteredFactory()).
WithMicrosoftDependencyInjectionRules().
WithUseInterpretation());
}

or
DryIoC: 6.0.0-preview-07
DryIoc.Microsoft.DependencyInjection: 8.0.0-preview-02

Configuration
private IocManager()
{
Rules rules = DryIocAdapter.MicrosoftDependencyInjectionRules.WithConcreteTypeDynamicRegistrations(reuse: Reuse.Transient).
With(Made.Of(FactoryMethod.ConstructorWithResolvableArguments)).
WithFuncAndLazyWithoutRegistration().
WithTrackingDisposableTransients().
WithFactorySelector(Rules.SelectLastRegisteredFactory()).
WithUseInterpretation();

this.Container = new Container(rules)
}

When I call Populate (iocManager.Container.Populate(mauiAppBuilder.Services);) the exception is thrown.

I have been working successfully with DryIoc, Xamarin, netStandard, AspNet.Core since 2019. The error occurs with net8 and Maui.

No matter which platform (Windows Machine, Android, iOS) is used

@ChristianM66

Thanks for the clarifying.
Sadly, nor exception message, nor the stack trace contains any DryIoc related information.
I would suggest to search MAUI code for specifics of the "Window already exists" condition.

Also in regard to the Rules.Default.WithConcreteTypeDynamicRegistrations(reuse: Reuse.Transient).
Could you remove it and check again?

@ChristianM66 Hi, I want to suggest trying DryIoc v6.0.0-preview-07 and check if the issue is reproducible.

@ChristianM66 any updates on the issue?
