Hi @Sanjay Kumar Jha , Would you mind sharing the detailed error message and the crash logs? And could you please provide some code snippets about your service? As noted in the Q&A FAQ: How to write a quality question

In addition, you could check if the service is only implemented on Android platform. For more details, you can refer to .NET MAUI invoking platform code - .NET MAUI | Microsoft Learn
From the image, you select the Android target, please try to select iOS. And you can configure multi-targeting, please see Configure .NET MAUI multi-targeting - .NET MAUI | Microsoft Learn

Hi,

I have built the App in Android version that is working fine on my end, but when i use the same code for IOS, it is not working.
Issues are as follows:-

1.When i choose targeted platform IOS and i run the application, It is not showing any kind of error. After showing splash screen it stops responding itself.

2.If dependency injection is working fine for Android version then i am unable to understand why the same code is not working in IOS version.

3.My services are not platform dependent. Only one service is platform dependent that i have already created as according to supported platform.

Note:Microsoft is not allowing to send code in zip format. Also it is not allowing to send video files so that anyone from your side can understand the situation in a very well mannered. I would say one thing, if i compare technical support of Apple and Microsoft then i will say Apple support is excellent. but Microsoft is not up to the mark that is very bad approach of Microsoft.
In my case I need support in which i can share my screen and explain my problem so that you can understand the problem. If there is any problem in .NET MAUI then it must be corrected before the final release.

So what you suggest now. In this way we will not reach to any conclusion.

Also i would suggest to provide option of sending code in Zip format and there should be an option of attaching video files.

Will it be possible that i can share my screen and explain my problem?

You could try to add breakpoints in the constructor and debug the app, then check if there are empty instances or null objects.

Also i would suggest to provide option of sending code in Zip format and there should be an option of attaching video files.

You could upload a basic minimal reproducible sample to GitHub or OneDrive or any wherever you prefer to, and you could attach the link here, then I will download and test it. Please be careful to post your security information.

Will it be possible that i can share my screen and explain my problem?

It is recommended to open a support ticket for this, you can contact our paid phone support at MS Support, and you will get 1:1 support on that.

If you have any other issues, please feel free to let me know.
