Switching between light theme and dark theme

To switch to light theme from dark theme, use the following code snippet.

{% highlight C# %} void UpdateTheme(object sender, System.EventArgs e) { ICollection mergedDictionaries = Application.Current.Resources.MergedDictionaries; var darkTheme = mergedDictionaries.OfType().FirstOrDefault(); if (darkTheme != null)
{ mergedDictionaries.Remove(darkTheme); } mergedDictionaries.Add(new LightTheme()); }

{% endhighlight %}

Similarly, to switch to dark theme from light theme, remove the light theme resource, and add the dark theme resource dictionary.
