It seems that something in the way NCrunch executes tests causes problems with reflection. Consequently I'm unable to set or access configuration properties with declared default value on configuration elements. All tests in example below fail with following exception when executing in NCrunch. All tests execute successfully in NUnit runner. If property DefaultValue is removed from configuration element property, all tests with exception of 'AccessPropertyWithDefaultValue' execute successfully in NCrunch and NUnit. Can this problem be fixed with appropriate configuration? Code:
System.Reflection.CustomAttributeFormatException : 'DefaultValue' property specified was not found.
