Does Mono / .NET 4.0 implement AppDomain.FirstChanceException?

I am porting a C# app from .NET on Windows to Mono on Linux (both using .NET 4.0). When compiling the code I get the following code:

Error CS1061: Type System.AppDomain does not contain a definition for FirstChanceException and no extension method FirstChanceException of type System.AppDomain could be found. Are you missing an assembly reference? (CS1061) (V8.Net-Console)

for the following code:

AppDomain.CurrentDomain.FirstChanceException += CurrentDomain_FirstChanceException;

When looking at AppDomain via Assembly Browser I do not see any definition for FirstChanceException. Is it missing from Mono or is it some issue on my machine? If it is missing, what alternative is available?

I just downloaded the Mono 3.2.1 source code and checked. I didn't see a FirstChanceException event declared in the AppDomain.cs code. I don't know if there's an alternative or not (I haven't had the need to use this event before), sorry. - Chris Sinclair
Yes, I've also found this code, so it seems like they just haven't implemented it: github.com/mono/mono/blob/… - Sergiy Belozorov
Yeah, I'm not too surprised. Definitely seems like something that would have to be implemented as part of the runtime itself (though I'm no expert on that; I could be completely wrong). I'd suggest maybe contacting the mono team or their specific community to see if there are any future plans to implement it, and if so, what the timeline is. - Chris Sinclair

According to the source file containing AppDomain class, this is not implemented on Mono yet.
