Find If Assembly Compiled in Debug Or Release Mode

1. Locate and run ildasm.exe application on your mashine
2. From the top menu select Open-> View-> MetaInfo-> Show!
3. Find following text "System.Diagnostics.DebuggableAttribute". You should see something like

CustomAttribute Type: 0a00000d
CustomAttributeName: System.Diagnostics.DebuggableAttribute :: instance void .ctor(value class DebuggingModes)
Length: 8
Value : 01 00 07 01 00 00 00 00 > <
ctor args: ( )

4. Value of this attribute for Release Version the value should be

Value : 01 00 07 01 00 00 00 00

and for Debug Version it will look like

Value : 01 00 02 00 00 00 00 00
