Converted a xy coordinate to lat/long using Pro SDK

Have anyone converted a xy coordinate to lat/long using Pro SDK?  I just could not get the correct numbers.

Hi Fayu,

 You can use this code snippet: 

<SPAN class="keyword token">return</SPAN> QueuedTask<SPAN class="punctuation token">.</SPAN><SPAN class="token function">Run</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">(</SPAN><SPAN class="punctuation token">)</SPAN> <SPAN class="operator token">=</SPAN><SPAN class="operator token">></SPAN> <SPAN class="punctuation token">{</SPAN>
&nbsp; <SPAN class="keyword token">var</SPAN> activeMapView <SPAN class="operator token">=</SPAN> MapView<SPAN class="punctuation token">.</SPAN>Active<SPAN class="punctuation token">;</SPAN>
&nbsp; MapPoint zoomToPnt <SPAN class="operator token">=</SPAN> MapPointBuilder<SPAN class="punctuation token">.</SPAN><SPAN class="token function">CreateMapPoint</SPAN><SPAN class="punctuation token">(</SPAN>coord<SPAN class="punctuation token">.</SPAN>Longitude<SPAN class="punctuation token">,</SPAN> coord<SPAN class="punctuation token">.</SPAN>Latitude<SPAN class="punctuation token">,</SPAN> SpatialReferences<SPAN class="punctuation token">.</SPAN>WGS84<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>

<SPAN class="punctuation token">}</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">;</SPAN>‍‍‍‍‍‍‍‍‍‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

There are multiple samples among the community samples that use projection, just search for "Instance.Project" on the community samples GitHub repo for a list of usages.
