What's the difference setting Embed Interop Types true and false in Visual Studio?

Question

In Visual Studio, when adding one reference to the project, the properties window has an option Embed Inteop Types, should we set it to True or

Answer 1

I noticed that when it's set to false, I'm able to see the value of an item using the debugger. When it was set to true, I was getting an error - item.FullName.GetValue The embedded interop type 'FullName' does not contain a definition for 'QBFC11Lib.IItemInventoryRet' since it was not used in the compiled assembly. Consider casting to object or changing the 'Embed Interop Types' property to true.
