If anyone has been looking for the best way to deploy the C++ Runtime with your esri Runtime WPF app, here's the content we brought into our app package. We copy from these locations:
32-bit:
c:\windows\syswow64*140.dll
C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86\*
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x86\Microsoft.VC140.CRT*
64-bit:
c:\windows\system32*140.dll
C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64\*
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x64\Microsoft.VC140.CRT*
32-bit files go into the ArcGISRuntime100.11\client32 folder. 64-bit files go into the ArcGISRuntime100.11\client64 folder.
