Thank you for contacting us.
Unfortunately there is a known issue when using our SDKs with other SDKs (Bing Maps SDK in particular) in processor specific configuration (x86, x64, ARM). In order to workaround it, you can reference our binaries directly (from the installation folder) and not using our SDK. Currently we are not aware of other workaround of this issue (while still using our SDKs).
We hope that the suggested approach is applicable for you.
