Look up the text for a label in other languages than en-us

The dev boxes only comes with source label files files for en-us, so finding a text from a label in another language is not easy.

You could use a tool like RedGate .NET Decompiler to decompile the dll's of the compiled label files.

But, new to me, you can also just use the Meta Data API of Dynamics like this example:
https://[baseuri]/Metadata/Labels(Id='@SYS333000', Language='da')
