After loading VisualMicro tools into Visual Studio,  I have been able to use Visual Studio as an IDE for the Arduino and it works great.   Now when I try to execute a C# project I get the following error message:


"Unable to start debugging.  The startup project cannot be launched. Ensure that the correct project is set at the startup project.  The start up project can be changed by selecting the 'Set as Startup Project' command from the right click menu in Solution Explorer."

How do I fix this to allow both C# code and Arduino code to be worked with and executed?

I am using the C# independent of the Arduino.  I am guessing that the IDE is still looking at the serial connection for use with the Arduino, in lieu of executing the C# code as a console application.

Last time this happened, I removed Visual Studio and reloaded it, without installing the Visual Micro Libraries.

  I started using Visual Studio for writing C# .net and console applications.  Recently I found out that Visual Studio could be used for programming the Arduino (using Visual Micro) and have been using it that way for sometime.  When I tried jumping back into writing a C# console application, the error message occurred.

Hi Tim;

  Attached is a screen shot of the error message and the C# code (which is very simple).
I appreciate your help.  It must be something simple that I am not understanding...
Thank You

I tried your .net core project and it starts and debugs fine with visual micro installed.

Maybe a vs2017 bug please make sure you are on the latest release of visual studio

Thanks

Hi,

.Net core is the new platform from Microsoft. It will eventually replace .net framework.

.Net core can run windows, mac and linux.

The error encountered is probably missing .net core debug tools but I am not entirely sure. Visual Micro doesn't have any connection to it.
