Even developers with lots of experience in XAML know that experimentation is rewarding. But these XAML syntax features use XML in unique ways.

XAML is basically XML, but XAML has some unique syntax features. They are discussed in detail in the articles below, which conclude with an introduction to using XAML for implementing MVVM.

The CPU Usage tool measures the CPU’s resources in terms of how much time each core in the CPU spends executing your code, commonly known as CPU time.

If you do that, please let us know what feature you missed the most so we can prioritize adding to the new tool.

Let’s take a look at how to use the key features of the tool to solve a performance problem in a simple app.

Samples are taken once a millisecond and the measured CPU time is generally accurate to /- sqrt(t) ms.

The call tree at the bottom shows a breakdown of the CPU activity in the selected time range by both the relative percentage of CPU utilization and absolute amount of CPU time attributed to each function.

It can be difficult to know where to start when you want to make your code run faster.

In many cases the CPU is the bottleneck when performance problems arise, and you can often start your performance investigation by looking at what code the CPU is executing.

NET framework, but it has found its greatest utility in defining the layout of user interfaces within the Windows Presentation Foundation (WPF), Silverlight, the Windows Runtime, and the Universal Windows Platform (UWP). Forms, the cross-platform natively-based programming interface for i OS, Android, and UWP mobile devices. Forms developer can define user interfaces using all the Xamarin.

Forms views, layouts, and pages, as well as custom classes.

First, we run the CPU Usage tool by going to Debug - We can see that out of the 8.161 seconds of selected time, there was 7613 ms of CPU time used by our app.

Since the CPU time is close to the elapsed time, it is likely that this operation is CPU-bound and we can reduce the overall time it takes to generate the list of prime numbers by reducing our usage of the CPU.

You can select regions of elapsed time on the above graph to see what functions were using the CPU during that time, which is useful for isolating specific performance issues.
