Investigate why the Host sends Json bodies as Strings in the TypedData

[TylerLeonhardt]

The host is packaging the Body from the request as a String rather than Json in TypedData

This is the data I get from the host:

I'm invoking the script with Invoke-WebRequest in PowerShell:

iwr http://localhost:7071/api/MyHttpTrigger -Method Post -Body '{"Name": "Tyler"}'

Is this a bug in the host or by design and I need to attempt to deserialize it?

cc @pragnagopa + @asavaritayal

[pragnagopa]

Very likely an issue on the host side. I will look into this and confirm.

[pragnagopa]

@mhoeger - Can you please investigate and also add unit test for this in host repo?

[TylerLeonhardt]

@mhoeger please let me know if there's any other info you'd like me to supply

[TylerLeonhardt]

@daxian-dbw said this is working now since we switched to whatever version of the host ships in beta37 of CLI
