Using Notepad, three decades old, 200kb in size, preinstalled tool:
notepad appname.exe
, F3
until .NET Framework,version=vX.Y
shows upv2.
... still 100 times easier then installing gigabytes of dot net analyzer tools and garbage studios.Any other editor/viewer can open binaries too, like Notepad++ or totalCommander's great text/hex viewer lister.
