Visual Studio 2017 - Emulators Disappeared

Question

Yesterday I've installed

• Windows 10 Fall Creators Update SDK (ver. 10.0.16299.15),
• Microsoft Mobile Emulator for Windows 10 (ver. 15254.1)

After installing new SDK, my emulators are completely gone from Run Button. Even local machine. I have Visual Studio 2017 (ver. 15.4.1). Second thing is when I run Visual Studio Installer I see required things for SDKs and emulators are checked.

SDK and Mobile Emulator versions are confusing me. Also, I tired repairing Visual Studio but no luck.

Edit: All that's listed on the Run Button is 'Start' and 'Download new emulators' (not even local machine) .

Thanks for your help.

UPDATE

I have 4 projects in solution. 1 UWP project, 2 Class Library projects and 1 project for Test. They all have same Target/min version (as you can see in picture).

Also, installed SDKs and emulators

Answer 1

Well, I did clean install for VS2017. Deleted every piece of VS app. Re-installed. Worked.

Answer 2

The issue may be caused by the Minimum version setting in the UWP project. Go to the Project Properties > Application tab > Targeting area and adjust the Min version. This will cause the solution to close and reopen. Check the Run menu when it reopens.

Here is another explanation of what is going on and what you can do about it.
