Model Validation Exception

[IllarionRUS]

Hi, too, can not turn off obfuscation, found that the problem is to rename, cut off the class renaming "-", it is still not working. [Obfuscation(Exclude = false, Feature = "-rename")]
'System.Data.Entity.ModelConfiguration.ModelValidationException' occurred in Unknown Module.
Additional information: During the creation of the model validation errors found. MyClass:: To EntityType "MyClass" keys are not defined. Identify key for this EntityType. If you have thoughts prompt.
A complete shutdown module renaming, obfuscation works.
