How to send a form/notification to user from a DLL? - visual-studio

Question

I have a DLL .
And want to send a form/notification to user( who would reference my dll) from this dll.
I just want to build a function inside one class in my dll such that ->, once a user runs his local program and references my dll -> and calls a function that is present in dll -> that particular function should show up a form/notification to user ( from some functionalities in dll )? Is there any other method for the same?
I tried converting the library to a Winform from class library type and that would change its properties into an executable and it would demand presence of the main function. But I am just building a library that can be referenced and when called by the user produces a form at their end?
I tried toast notifications but not .show() method doesnt work inside new ToastContentBuilder() while i call that in a fucntion from my library . Otherwise as an idenpendant console app , it worked fine
Is there a way I can have a project for toast notification in the same solution as that of my library and then call from a class in my main library -> the function present in this different project for toast notif and would produce the toast notification.

Answer 1

You can try the following steps to send a notification to the user from the dll.
First, please create a class library(Target Framework is .NET Core 3.1) called TestDll.
Second, you could install the nuget-package Microsoft.Toolkit.Uwp.Notifications in the class library.
Third, you can add a class and refer to the following code example.
namespace TestDll
{
public class Example
{
public void Setnotifications()
{
new ToastContentBuilder().AddArgument("action", "viewConversation")
.AddArgument("conversationId", 9813)
.AddText("Ev2 Compiler Library")
.AddText("Allow sending build Data to Microsoft")
.AddButton(new ToastButton()
.SetContent("Yes")
.AddArgument("action", "reply")
.SetBackgroundActivation())
.AddButton(new ToastButton()
.SetContent("No")
.AddArgument("action", "like")
.SetBackgroundActivation())
.SetToastScenario(ToastScenario.Reminder)
.Show();
}
}
}
Fourth, please rebuild the class lib and create a console app(Target Framework is .NET Core 3.1).
Fifth, we can add the project reference TestDll to the console app and write the following example in the main method.
static void Main(string[] args)
{
Example example = new Example();
example.Setnotifications();
}
Finally, we can see the notification in the right bottom of computer like the following:
Besides, the problem about 'toast notifications but not .show() method' maybe that you used .net standard framework, you can solve the problem by changing to the .net core framwork.
