Error when using Visual Studio 2022

Getting Started
1

Hi,
I followed the tutorial steps and created a very first Basic Plugin using Projucer. I selected Visual Studio 2022. Did no code change at all and tried to compile the generated files. Got these errors:

When building it for Visual Studio 2019 and compile with Visual Studio 2019, it works.

Well, it may happen for several reasons. I will suggest that you ensure there are no background processes or antivirus software that could slow down the form interaction.
Thanks

My guess is that Dropbox is trying to interact with temporary files created by the compiler.

It’s probably not a good idea to have your build folder in Dropbox - I’d recommend excluding that folder (if possible, I don’t know whether Dropbox supports exclusions), or moving the entire project out of Dropbox and using a proper source-code management system like Git instead.

You are right!
When I pause Dropbox it compiles correctly.
The strange thing is that VS 2019 doesn’t seem to have this problem.

Thx.
