### Change Description
|
||
|
|
In the .NET Framework 4.6.2, the runtime throws a `T:System.NullReferenceException` when retrieving a `P:System.Web.HttpRuntime.AppDomainAppPath` value that includes null characters.
|
||
|
|
|
||
|
|
In the .NET Framework 4.6.1 and earlier versions, the runtime throws an `T:System.ArgumentNullException`.

### Recommended Action

|
|
You can do either of the follow to respond to this change:
|
||
|
|
|
||
|
|
- Handle the `T:System.NullReferenceException` if you application is running on the .NET Framework 4.6.2.
|
||
|
|
|
||
