Hi Bob,

Please switch on tools>visual micro>verbose messeges

Then click Build>clean solution

Then build and email the output to info [at] visualmicro.com

Please also state which hardware, arduino version and visual studio version you are using

Thanks

Hello Tim,
If you looked at the visual studio project file that I sent you then you should know that the 3 rules you specified are in fact satisfied. You are correct that it doesn't detect it as a visual micro project and intercept it, the question is WHY? If I open it as a sketch (instead of a project) it works. If I close and re-open .MsgPumpTest.vsarduino.h in the editor before building it works. If I just open the project and build it fails. Please take another look and see if you can figure out why this happens. At this point I only have VS 2013 Premium installed (I had 6, 2005, 2008, 2010 but did a clean install when I went to 2013) so I can't check this behavior against anything else.

Thanks.

Hi Bob,

Thanks for the output

When it fails can you please email the contents of the "Micro Build" output window

Thanks

Hi Bob,

I have tried out your project and it works okay for me in all situations. Sorry to say.

I can also say that when you use file>open>sketch, if the sketch project already exists, we run the VS open project macro. So this makes it very confusing because Visual Micro doesn't do any clever (or otherwise) when a sketch opens. We are just opening a standard VS project.

The vsarduino can be ignored from all discussion. I think opening it adds some line feeds that VS likes when it wrongly attempts to compile regardless of success or fail.

You say that other projects work fine for you? Are the other test sketches located in the same place on your pc. It's the only thing I can think of that might be different. 

I can't at the moment think what would cause this other than another Visual Studio extension or add-in is preventing Visual Micro from managing the build. I know this doesn't make sense because it works when you open via sketch>open but it's all I can think of.

Can you confirm that if you use File>Sketch>open the compile ALWAYS works?

Thanks

Sorry to be a pain but are you saying that if you close and re-open vsarduino the Win32 compile works or the Arduino compile?

And Arduino compile will show something like this and nothing else

Compiling sketch xyz for board
Binary sketch size: 1,008 bytes (used 3% of a 32,256 byte maximum) (10.64 secs)
Minimum Memory Usage: 9 bytes (0% of a 2048 byte maximum) 

I'm going to drop this whole thing for now because I found another workaround.  If I simply double click the solution file (instead of file-open-project/solution) it opens in studio and builds correctly. This seems to be a plug-in issue but I don't have time to pursue this right now (and I don't want to waste your time either). I might come back to it later and try to figure out what is happening. If I do I'll follow up on this thread.
