Is there a way to log or intercept First Chance Exceptions

Closed 5 years ago.
Is there a way to catch First-Chance exceptions, and log them without running under a debugger?
I suppose another way to ask the question is can I write something that will act like a debugger being attached to my process and see what is going wrong while it happens?
If you are on .NET 4.0, you can use theAppDomain.FirstChanceExceptionevent to get notification of exceptions.

Troubleshooting .NET "Fatal Execution Engine Error"
(5 answers)

While I was debugging a simple bit of C#. I got the error 'internal clr error 0x80131506' and the program being debugged crashed. It's .NET Core 3.1 running on Windows 10 x64.
The code wasn't doing much interesting, just calling a method that iterates an array, from another static method in a class, ultimately called by a console application Main method.
I'd be interested to know if there is some way to look up these types of error codes, I couldn't find anything in my search - but perhaps I'm not searching for the correct thing, so any pointers would be appreciated.
After YEARS of using Unity, I finally got this error.
Similar to a lot of other weird and unexplainable errors.
When in doubt, reboot!
Deleted Library folder and rebuilt it - problem gone!

Today while i was debugging my code step by step i encountered one message while debugging my ASP.net web api.
I had never encountered any such message. What is this message and why it came, what is the main purpose of it. Can anybody explain.
Visual Studio is asking that its going to skip some code and debug your program. And this message is to ask that do you need to be informed whenever this happens.
If you want to be informed in future, you can select "Yes" otherwise select "No"
You can simply ignore this and continue.

What kind of Exceptions cannot be handled? [duplicate]
(2 answers)

So from http://msdn.microsoft.com/en-us/library/ms173161.aspx
Once an exception is thrown, it propagates up the call stack until a catch statement for the exception is found.
So the implcation is that all exception typess can be either caught by a catch(ExceptionType) or a generic catch.
However this is plainly not true. For example AccessViolationException bypasses standard exception handling
How to handle AccessViolationException
So what other exceptions also bypass standard exception handling?
I would say that a StackOverflowException is most likely unhandled, I'm not aware of others.

Very simple really - is there a way to check and make a list of all exceptions that a method might throw? I have used try/catch but I want to make sure I didn't miss anything, and going through big files line by line to check if that line is throwing something that might be uncaught on runtime is a pain...
Oh yeah, I am using C#, .NET 4.5 and VS2012 PRO.
Thanks good people.
In C#, all objects that are thrown must derive from System.Exception. If you catch System.Exception, you catch them all, no matter what subtype.

C# does not support checked exceptions. You can read up on why the original design did not include checked exceptions.

No, there's no such distinction in C#, nor in many other modern languages, even those that run in the JVM (such as Scala).

Nope, it does not. No. Thankfully!

without the CLR itself supporting checked exceptions, it would be effectively impossible for C# to do so alone.
