Can we use DelegateDecomiler when we obfuscate the code?

[jojose]

We are using 'Dotfuscator' to obfuscate the dlls. We started using DelegateDecompiler for supporting some functionality when using entity framework. The issue is that after obfuscation, the EF method call fails. We tried to Exclude the classes used in the EF calls from obfuscation but still the issue is there.

The following is the error we are getting

System.AggregateException: One or more errors occurred. ---> System.ArgumentException: metadataToken Parameter name: Token 0x5d07727e is not a valid MemberInfo token in the scope of module

When I posted this at https://github.com/hazzik/DelegateDecompiler/issues/103

I have been adviced to post it here.

Thanks
