(0xE0434352 - CLR Exception) is being logged sometimes after a Host Shutdown has occurred on v2 Runtime.

#### Investigative information

Please provide the following:

- Timestamp: Reproducible in general but specifically 2018-12-05T19:37 to 2018-12-06T19:37
- Function App version (1.0 or 2.0): 2.0
- Function App name: FinTestFunctionsApps
- Function name(s) (as appropriate):TestFinTimerBlob
- Invocation ID:
- Region:West Europe

#### Repro steps

Provide the steps required to reproduce the problem:

1. Create a Function App with two Functions.

Blob Trigger

public static void Run(Stream myBlob, string name, ILogger log)
{
log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
}

Timer Trigger

using System;

public static void Run(TimerInfo myTimer, out string outputBlob, ILogger log)
{
log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
outputBlob = DateTime.Now.ToString();
}

#### Expected behavior

Provide a description of the expected behavior.

These Functions are running as expected but the Diagnose and Solve blade Application Crashes detector should not show CLR Exceptions on Exit.

#### Actual behavior

Provide a description of the actual behavior observed.

These Functions are running as expected but the Diagnose and Solve blade Application Crashes detector shows CLR Exceptions on Exit. 0xE0434352

#### Known workarounds

Provide a description of any known workarounds.

No Workarounds exist.

The report names no repository files, tests, or code entry points. Start by reproducing the two-function C# Blob Trigger and Timer Trigger setup, then correlate the 0xE0434352 exit with the logged “Host shutdown completed” event; done means intentional host shutdowns no longer appear as application crashes.
