How to mock ISerializable classes with Moq?

Question

I'm completly new to Moq and now trying to create a mock for System.Reflection.Assembly class. I'm using this code:

var mockAssembly = new Mock<Assembly>(); 
mockAssembly.Setup( x => x.GetTypes() ).Returns( new Type[] { 
    typeof( Type1 ), 
    typeof( Type2 ) 
} );

But when I run tests I get next exception:

System.ArgumentException : The type System.Reflection.Assembly 
implements ISerializable, but failed to provide a deserialization 
constructor 
Stack Trace:

Could you reccomend me the right way to mock ISerializable classes (like System.Reflection.Assembly) with Moq.

Thanks in advance!

Answer 1

The issue is not with ISerializable interface. You can mock ISerializable classes.

Notice the exception message:

The type System.Reflection.Assembly implements ISerializable, but failed to provide a deserialization constructor

Problem is, that Assembly does not provide deserialization constructor.
