[Breaking change]: ExceptionCollection would now throw 'ArgumentException` if input is not of Exception type. #33695
Description
Description
Similar to #33694, We are now enforcing a specific type when creating an ExceptionCollection. The type being passed must be of the exception type, otherwise an ArgumentException will be thrown.
Version
.NET 8 Preview 1
Previous behavior
Previously, the creation of an ExceptionCollection object did not check for the type passed in and could potentially delay failure until later in the process. No exceptions were thrown during the object creation.
New behavior
the creation of an ExceptionCollection object will throw an ArgumentException if the type passed in is of not exception type.
Type of breaking change
- Binary incompatible: Existing binaries may encounter a breaking change in behavior, such as failure to load or execute, and if so, require recompilation.
- Source incompatible: When recompiled using the new SDK or component or to target the new runtime, existing source code may require source changes to compile successfully.
- Behavioral change: Existing binaries may behave differently at run time.
Reason for change
Existing documentation clearly notes that type should be of type exception. Making exceptions consistent across codebase.
Recommended action
This change should not have a significant impact on most scenarios. However, if users were previously not handling exceptions will now need to make changes to handle the ArgumentException.
