I have installed version along with the service pack.  I am creating an application for displaying sensory information taken from my RPi, this application contains a few pages to navigate between.  However, I am noticing my application memory usage keeps going up each time I navigate back to the page having the SfCircularGauge coded on it.  So I keep toggling between a blank page and the SfCircularGauge coded page, what do you know the memory keeps going up each time rendering the SfCircularGauge coded page.  Eventually rendering becomes very slow and then the application crashes.  So I created a sample application to ensure that I am not doing one of my usual stupidity and same problem.  Note:  I am running these applications on my laptop with windows 10 and VS2017 RC.

I have attached a zip my sample application.

How do I go about freeing up the memory usage of the SfCircularGauge control?

Hi Kirklyn, 
Thanks for your interest in Syncfusion products. 
We have analyzed the memory usage get increases, while navigating to/from SfCircularGauge page. SfCircularGauge memory usage can be reduced by using SfCircularGauge Dispose method while unloading the corresponding SfCircularGauge page, which is used to release the unmanaged resources in SfCircularGauge.  
Based on that we have modified the given sample to release the gauge memory usage and please find the sample from below link.

Thanks, for the response. Following your example, I am now seeing a consistent memory usage switching to and from the page having the SfCircularGauge control.
