Tim,

What am I missing here? I am using the latest VS2017 and VMicro and after creating 3 projects in a single solution, VM does not switch between the devices/COM Ports for the projects when I change my Startup Project.

Note: I did not create the projects separately then add them to a solution, I created the projects within the solution.

Thanks,
Khalil

Sorry, I thought my issue was directly related to the question being asked which is why I added it here.

So just so I understand it is not possible to have different boards in a single solution and switch between them without manually having to change the board selection/COM?

Thanks,
Khalil

Ok maybe it is a terminology issue. Here's an example.

I create an Arduino project (say Project A) using the VM addin in VS. Once the project is created, I change the board type and COM port using the dropdown menu in the VM toolbar. Say I create one for the ESP8266 on COM5.

Then I add another new project to the solution (Project B) and using the same procedure above create one for the WiFi-Lora 32 on COM7. 

What I would expect is as I switch between the projects, the board type and the COM port would switch automatically. So when on Project A - dropdown shows ESP8266 and COM5. Project B - WiFi-Lora 32 and COM7

I guess I am not seeing where VM saves the board for each project. Because as I switch between the projects they don't compile if the toolbar options are not set accordingly.

Ok yes that was the issue.

What I did was create the first project that already had the device I wanted and did not actively choose it.

So when I switched back and forth it would not switch.

Sorry about that. Thanks for the help.
