Why won't the Bing Maps for Visual Studio 2013 C++ open up? -

i've done listed below bing maps api working. i've created basic bing map key use, when running app screen shows map , red cross on it.

1. added map tool project
2. changed build configuration win32, said sint compatible x64 ( have windows 8.1 64 bit running though )
3. added reference "bing maps c#, c++, or visual basic" project

4. added following piece of code :

   <bm:map credentials="insert_your_bing_maps_key" x:name="mymap"      maptype="aerial" zoomlevel="12"     width="600" height="800">     <bm:map.center>         <bm:location latitude="46.227480" longitude="-122.192955" />     </bm:map.center> </bm:map> 

5. inserted bing map key required position.

all above listed on site https://msdn.microsoft.com/en-in/library/hh846489.aspx unable bing maps working. thank in advance.

it seems bing maps api country or region restricted. changing country settings of windows system made api work intended.
