prism | user space stealth reverse shell backdoor , written in pure C

I am developing a modular WPF application with Prism in .Net Core 5.0 (using MVVM, DryIoc) and I would like to have a module that is not a WPF module, i.e., a module with functionality that can be used by any other module. I don't want any project reference, because I want to keep the loosely coupled idea of the modules. My first question is: is it conceptually correct? Or is it mandatory that a module has a screen? I guess it should be ok.

The second and more important (for me) is, what would be the best way to create the instance?

This is the project (I know I should review the names in this project):

HotfixSearcher is the main class, the one I need to get instantiated. In this class, for example, I subscribe to some events. And this is the class that implements the IModule interface (the module class):

I am using a Telerik RadNumericUpDown control in a C# Prism MVVM application. When my users hold down the up or down arrow the control increments the value of the property it is bound to. However, when that property value is changed, a command is sent to another device over a communications line with some latency. Also, there are instances where the device doesn't succeed in changing the value of this parameter.

Here is the code from my view.

I am using a plugin that is creating a custom payment type where the user can fill in a custom payment ID. The thing is, I want that custom payment ID stored in an ACF field as post meta on the WooCommerce order edit page. I have created an ACF field named 'kkpayment' for this task. I figured the rest should be done using update_field($selector, $value, [$post_id]);. I have created a PHP function for this task. However, my code doesn't seem to work. Am I missing something obvious?

My function for updating the ACF field:

im currently digging through the github page, but Im unable to figure out how to set the tabSize property on my prism editor, if anyone has any experience and is willing to share it I would greatly appreciate it!

Hope everyone is safe.

I need help implementing INotifyDataErrorInfo interface with SfTextBoxEx placed inside SfTextInputLayout.

WPF with MVVM using Caliburn.Micro framework.

Please find following project structure to understand by question.

1) FolderName : Infrastructure File : ValidatedPropertyChangedBase.cs

--It contains implementation for INotifyDataErrorInfo.

2) FolderName : Model File : TestModel.cs --Contains two properties with inherited from ValidatedPropertyChangedBase --Also contains the class for Validation of properties using FluentValidation

4) FolderName : View File : HomeView.xaml --Standard window with two SfTextInputLayout with SfTextBoxExt

4) FolderName : ViewModel File : HomeViewModel.cs --standard view model with Model as property with Validation triggering. --Here if i put breakpoint on validation method i can see that error returned is correct but somehow it is not triggering the UI to show the error message. --I've already set ValidatesOnNotifyDataError=true while binding the property with textbox.

Please check and guide me if something is wrong. NOTE : I am using syncfusion controls but I tried with standard text box also, it is not triggering the errorchanged event.

Also I've used IntoifyDataError implementation from: https://www.thetechgrandma.com/2017/05/wpf-prism-inotifydataerrorinfo-and.html

I have a SignalR service and an Uno Platform WASM Client (with Prism). I want to call a hub method, which returns a model. The problem is, i have two identical models (Properties, Methods, etc.) but the client can only receive one of them upon calling the hub methods. With the other model a exception gets thrown on deserialization.

Hub:

I have a code that is used to select certain elements, the code works great when you onSelect and it shows the right option value. The problem is I am not sure how to show the selected option when we search a value onSelect of the dropdown then it's not working.
