xnb edit

".XNB files are binary files of data that has been processed by the build
system so are not editable. Is there a particular reason you wanted to
edit them directly"

bu bağlamda şeylere denk geldim sadece.

"It also includes an example .xnb parser, written in native C++,
which demonstrates how to parse a compiled XNB file by printing its
contents to the screen. This can be used as a reference to help you
understand how to write your own XNB loader, and also as a debugging
tool for investigating exactly what data is contained within an XNB
file."

buradan anladığım kadarıyla da direk edit etmek mümkün görünmüyor. Decompile compile edilirse belki.
Filewievpro diye birşey var bir bakın isterseniz.
