How to debug System.ArgumentException in Output window?

Question

I'm using .NET Core 2.2 with EF and when queries are being run against database, I see a bunch of ArgumentExceptions being logged in the Output -> Debug window such as:

Exception thrown: 'System.ArgumentException' in System.Linq.Expressions.dll

The thing is my app is working perfectly fine, I get proper results and everything. I see like a hundred of these in the Visual studio's debug for no apparent reason.

Is there anyway I could find more information about these exceptions? Maybe let Visual studio break on them or something like that?

Edit: This did not happen on a different machine. I guess something bad is happening with my system and I could not tell what.

try to check Debug -> Windows -> Exception Settings->Common Language Runtime Exceptions checkbox for the System.ArgumentException. Also try to uncheck Debugging > General > Enable Just My Code. Does it change something? — AlbertK

So, the answer is to enable System.ArgumentException at Visual Studio setting Debug -> Windows -> Exception Settings->Common Language Runtime Exceptions.
