In Visual Studio 2015, changing the start up project does not list the emulators/devices available to deploy to. The issue occurs when using the drop down menu next to the Run button to select the start up project, but not when right-clicking the project in the solution explorer and selecting "Set as Start Up Project."
Some more observations:
- The project that is set as start up when the solution is first loaded will list the devices available
- Windows projects are unaffected by this issue, so if a Windows project is the start up project when loaded, no devices for Android / iOS will be listed.
### Steps to Reproduce
1. Create a new or load an existing cross platform project in VS 2015
2. Use the drop down menu next to the Run arrow to select a different start up project
### Expected Results
The Run button will list the available devices/emulators to deploy the project.
### Actual Results
The button will say "Start" and not list any devices/emulators
Right click the project in the solution explorer and choose "Set as Start Up Project"

I have this bug as well but I cannot view the bugs it is marked as a duplicate of and therefore can not see what the fix is.
## Status clarification for any users watching this bug
The other Bug 44487 just says that a candidate fix for this issue is included in the current Beta versions of Cycle 8 Service Release 1. That information is also recorded in the corresponding Release Blog post for the current Cycle 8 Service Release 1 Beta release:
> 44958 – No Available Devices are Listed After Changing Start Up
> Project via the Run button
@David, the work around is to right-click the project and select the device from there rather than the menu bar.
