Unusual and erroneus System.IO.FileNotFoundException error

Postby ak98 » Mon Aug 15, 2011 9:51 am

I have a DN2 application that when processed by smart assembly , fails to run with the following error as reported by the automated reporting from SA. Note that the error mentions DN4 System.Drawing. The machine has DN4 installed(its the development machine)


System.IO.FileNotFoundException: Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

Further dicking around and debugging has tracked the error down to Resource manager
i.e. System.Resources.ResourceManager.GetObject(String name)

Because of renaming / obfuscation the resource which is a System.Drawing.Image cannot be loaded from the local form resource.

I wonder why it is translated to a System.IO.FileNotFoundException.


Here is obfuscated and then decoded stacktrace

I will not be able to use SA if this error cannot be eradicated.

I think that the SA obuscation has corrupted the Resource lookup on winform local resources.

Probably. SmartAssembly obfuscation can change the class name of the Windows Form and that means it has to change the name of the corresponding resource file for that form. Normally this is working just fine but we have had a few reports in some cases that localized resources may not get renamed, for instance if you have a Form1.FR-fr.resources file it may not get renamed.

This is because out-of-the box, Visual Studio will automatically turn these resources into satellite resource DLLs, but of course there are ways to manipulate VS to embed the resources instead. So it may be worthwhile to find out the name of the resource it's trying to locate and that information should be in your debugger.

I found that the path from my "SetEnv.cmd" did not include C:\\Program Files\\Microsoft SDKs\\Windows\\v7.0A only C:\\Program Files\\Microsoft SDKs\\Windows\\v7.1 which somehow did not contain resgen.exe. So in effect the resources were never compiled into the final assemblies.
Interestingly when build with VS it was OK, so only commandline builds failed.
