windows-phone-7 - windows phone 8 old map vs new map

Question

I have a two WP8 projects. This is projects with map. First project with new Nokia maps and second project with old Bing maps. I noticed inappropriate behavior of old maps. They consume large amounts of memory, and when I go away from the maps then the memory is not freed. In WP7 Bing maps behave differently, it spent as much RAM memory, but when I go away from the map, the memory is immediately freed. How can I return the memory, I have a big problem with old maps, I exceed the limit of 90 Mb in my project ..

Screenshots below.

Any help.

Thanks in advance!

我不知道这是否可以帮助你，但我发现了这个

仅供参考：对于 Windows Phone 8 地图控件，您需要使用 Microsoft.Phone.Maps.Controls 中的 TileSource 类。（即 Microsoft.Phone.Maps.Controls.TileSource）

您可以显示静态地图，为此使用 Jeff Wilcox 库。在这里查看http://www.jeff.wilcox.name/2012/01/jeffwilcox-maps/。
