Hi @MateuszKlatecki,

I'm nanoFramework bot.
Thank you for your contribution!

I'm afraid this not possible because metadataprocessor strips out the "content" for the custom attributes. Only the attribute type is preserved and makes it to the portable executable.

For this to work it the processor would have to be changed.
