Hi there,

Thanks for letting us know about this problem. I really appreciate this.

Would it be possible that you zip the assembly where that happens and send it over to my email - alexander.dimitrov at telerik.com? Rather unfortunately, that seems to be the only way to reproduce that problem.

Thank you in advance.

Regards,

Hello Richard,

Thank you for sending me the assembly. Your help is very appreciated.

It looks like the assembly causing the problem is post-processed with some tool after compilation. Normally this would be an obfuscator or MSIL optimizer.  Rather unfortunately, this is not a supported scenario in JustDecompile.
