System.BadImageFormatException occurred when build in Release Mode
.net, assembly-resolution, c#
Solution
More than a Debug/Release mode I'll say it's a 32 vs 64 bits problem. Probably you have the Platform target for the Debug mode to Auto and for the Release mode to 32/64 bits and you are using a dll that is only 32 or 64 bits, so in Debug (Platform target Auto) mode the .NET can "select" between 32 and 64 bits to be compatible with the dll, while in Release (Platform target 32 or 64 bits) it can't.
(note that if you have multiple projects in the same solution you have to check all the projects properties for this! It's in the properties of each project, Build, Platform target)
Problem
I am referencing an exe file in a dll. When run in DEBUG mode everything runs fine but when run in Release mode below exception is thrown ``` System.BadImageFormatException occurred HResult=-2147024885 Message=Could not load file or assembly 'Presensoft.InlineMarker, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.
