Change your Window_Loaded
event method to async
and do an await
on the Init
method, Event Handler methods are an exception. using async void
instead of async Task
is ok in this scenario. - Reference (Should I avoid 'async void' event handlers?):
private async void Window_Loaded(object sender, RoutedEventArgs e)
{
await Handler.Init(Handler);
}

In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.
I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.
Agile software development stems from a philosophy that being agile means creating and responding to change swiftly. Agile means having the ability to adapt and respond to change without dissolving into chaos. Being Agile involves teamwork built on diverse capabilities, skills, and talents. Team members include both the business and software development sides working together to produce working software that meets or exceeds customer expectations continuously.
When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.
In today’s world, an organization’s most valuable resource is its customers. However, acquiring new customers in an increasingly competitive marketplace can be challenging while maintaining a strong bond with existing clients. Implementing a customer relationship management (CRM) system will allow your organization to keep track of important customer information. This will enable you to market your services and products to these customers better.
