So you mean, catch the root Exception class. Pretty much everyone agrees that's a bad idea, C# and Java both advice against that. But in the case of C# you have to do it, to avoid crashing all the time, because there's no reliable way to determine what exceptions can be expected. In Java the compiler will tell you what exceptions can be expected, but in C# you have to rely on documentation which is not reliable.

Not just Exception. Throwable.
I’ve seen too much code were some random problem in an Error - OutOfMemoryError for example when processing too much data (Eg call data records, payment records, analytic records, whatever). If it’s a batch processing job, you don’t want this problem for this specific entity causing the rest of your reports not to be sent.
I’ve also seen stupid things like RPC libraries silently swallow Errors and not report them properly to the caller, so we end up wrapping all RPC server endpoint methods in a try-catch-Throwable just so we can see the problem and log it.
