VB.NET in Azure Functions

FYI I was able to get a pure-VB.NET Azure Function working. It was pretty simple, really—here's what I did:

1. Created a C# sample using [this guidance](https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-your-first-function-visual-studio)
2. Created a new VB.NET project (in .NET Standard 2.0 instead of .NET Core 2.2—I ran into missing dependency problems while trying it in Core)
3. Converted the C# sample class using Telerik's [Code Converter](http://converter.telerik.com/)
4. Added the converted code to the VB.NET project (being careful to remove the redundant namespace declaration)
5. Per [this advice](https://stackoverflow.com/a/49790793/722393), added the `AzureFunctionsVersion` element to the VB.NET project's XML:

FunctionApp1
netstandard2.0
v2

6. Published and tested as normal

If you're using WebDeploy (uncheck the 'Run from package file' checkbox at first publish), you'll see a warning during deployment:

> Could not evaluate 'Microsoft.CSharp.dll' for extension metadata. Exception message: Could not load file or assembly 'Microsoft.CSharp, Version=4.0.4.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'

This warning can be safely ignored. Best guess, the assembly is probably only necessary as an interpreter for C# Script functions.

Due to my limited bandwidth I can only publish via WebDeploy, so I'm not aware of whether the warning occurs during a ZipDeploy (checking the Package checkbox).

And there we have it—an Azure Function in pure VB.NET.
