Update maxversiontested to Xaml Islands can be used in a VSTest project #4887
Description
Description
The Windows API DesktopWindowXamlSource requires the process to identify the version of the operating system it was tested on by specifying this in it manifest via maxversiontested (dot net had the same problem). Since tests run under testhost.exe, it must specify this to enable tests that use that XAML API to function.
if (CQuirksMode2::QuirkBlockXamlIslands())
{
// Xaml Islands are available from 19H1( 10.0.18226.0 ) release onwards.
