LogViewer: A Fast WPF Control Displaying Logging Information

For long running background tasks, it is helpful for the user to know which step is presently executed. LogViewer can collect this information multithreading safe and display it to the user as scrollable text. LogViewer allows the background thread to write formatted text without using any WPF code. When hundreds of messages need to get written per second, WPF would be too slow updating the GUI for each single message. LogViewer collects the messages and sends them 10 times per second to the WPF thread.
