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

When I posted this at hazzik/DelegateDecompiler#103

I have been adviced to post it here.

Thanks
