When I add a new .ino file to a project it initially shows up in the Solution Explorer as an Arduino file (Arduino "infinity" icon). On subsequent startups of VS the files are sometimes but not always shown as C++ files (++ icon). I can't find any trigger for this apparently random behaviour.

It's no big deal of course and it may be nothing to do with VM. It would be interesting to understand what's going on.

Hi Tim, thanks for the response.

I'm using VS 2019, although I saw the same behaviour when I was running VS 2015 until fairly recently. I click on the Add Code button in VS and then select the "Add empty Arduino .ino" option.

I should say that this really is no big deal, more of a curiosity really. It has no impact on functionality and I am a very contented (registered) user!

Thanks Tim. I agree, it looks like some sort of association problem but I've so far failed to find what triggers it. 

I've been one of your happy band of users for some years now and the fact that this is the first time I have posted on the forum tells you that it's worked out well for me. You have a great product and I couldn't imagine going back to the Arduino IDE! Thank you!

John.

I already gave VM five stars on 8th June 2016 and mean old Microsoft won't let me post another review! My opinion hasn't changed though: 

"Why did it take me so long to escape from the Arduino IDE to this vastly superior developer's environment? I am so impressed with this Visual Micro plug-in that I bought the Pro version well before the 45 day trial ran out.

"Anyone who uses this excellent product should support the author by paying for the Pro version. The support is excellent, it is not expensive and good software takes time and money to develop."

Thinks... I should send you some money for annual support. I didn't realise it was an option. [edit] Done!
