I've installed Gapps (Gapps CyanogenMod 13, Android 6.0 – Marshmallow (for Android 6.0 Gapps also) HDPI / MDPI / TINY: gapps-600-base-20151016-1-signed.zip) on my Android guest OS on VS Emulator for Android (using the 5.7" Marshmallow 6.0.0 XHDPI Phone API Level 23 device image) per https://mcmap.net/q/366979/-visual-studio-emulator-for-android-install-gapps-google-play-services (and got a success message in adb) and the only thing that is surfacing after restarting the emulator and guest OS is the Google Play Store. Launching it just opens a blank white screen which promptly closes.
I've even tried drag-and-drop install of the gapps zip and it says it is successful and prompts to shutdown (which the adb method didn't do), but there is still no change.

My problem with Marshmallow 6.0 image is that Add Account is missing Google type. It worked fine for me with older API images. – Ruttish
