[C#] Unhandled exception when try to recover

Sometimes I get an unhandled exception when calling Recover() method of FasterKV<Key, Value> class

System.Runtime.Serialization.SerializationException HResult=0x8013150C Message=Expecting element ‘ArrayOfstring’ from namespace ‘http://schemas.microsoft.com/2003/10/Serialization/Arrays’… Encountered ‘None’ with name ‘’, namespace ‘’.

Thanks for the feedback. Agreed, we will look into how to surface serialization exceptions to end user cleanly. CC @TedHartMS

Thanks, We will try using this fix in our product. Anyway I think exception which client cannot catch in try catch block is not good
