You have some object file or a library that was built using dmd 
2.060 or earlier and uses std.format. Maybe you are using some D 
library that was built separately (not as a part of your 
project)? If so, you need to rebuild that library with dmd 2.062. 
If that is not the case, this sounds like a bug in VisualD to me.
