FileSharing | Android File Sharing application using UDP , HTTP , FTP | SQL Database library

I'm developing a Java application. When I try to run the packaged version of application with command:

I am new to python/coding and I'm seeking some basic help to pull some elements from what I think is a dictionary. So I am executing the below.

I am having trouble running a sample ASP.NET MVC Core application provided by a template from Microsoft (eShopOnContainers).

When I trying to run the project using Visual Studio 2019, the below error is popped.

Here is my setup,

• Microsoft Visual Studio Enterprise 2019 Version 16.6.1
• docker desktop version 2.3.03

Does anyone have any idea to fix this?

[UPDATE]

The main error is:

In Xamarin.iOS Share Extension, I'd like to store my selected files (like pdf, images, word etc.) in my NSUserDefaults and when the main application starts, I'll have access to the files stored in it.

Here is my file class :

I'm not sure if this is a programming issue, but hopefully somebody can help me out anyway. On my iPhone (iOS 13.3) I'm trying to copy a file from OneDrive into my app's document folder using the Files app. I already set the keys UIFileSharingEnabled and LSSupportsOpeningDocumentsInPlace in the info.plist file so my app appears e.g. in the iTunes FileSharing section. It also appears as a possible target when I share a picture from the "Photos" app or if the source in "Files" is a standard app. But whenever the source is an MS Office app (OneDrive / Excel / Word / ...), the target app list is reduced to Office apps. No other app - neither mine nor standard apps like "Pages" or "Numbers" - appears in the list.

Does my app need a special setting to retrieve OneDrive files, or is this a more general Office issue?
