'Could not find file Microsoft.AspNetCore.WebUtilities.FileBufferingReadStream
I'm running an Azure Function locally in Visual Studio but receive the error "Could not find file 'C:\Users\kbiondi\AppData\Local\AzureFunctionsTools\Releases\4.13.0\cli_x64\Microsoft.AspNetCore.WebUtilities.FileBufferingReadStream'. (details below).
The code that triggers this error seems to be:
let! parameters = JsonTypeProvider.AsyncLoad(req.Body.ToString())
Using let parameters = JsonTypeProvider.Load(req.Body) the function runs without problem.
I have reloaded various nuget packages and the sdk, but this problem persists.

Based on the MICROSOFT DOCUMENTATION:-
F# script (.fsx) is only supported by version 1.x of the Azure Functions runtime. If you want to use F# with version 2.x and later versions of the runtime, you must use a precompiled F# class library project (.fs). You create, manage, and publish an F# class library project using Visual Studio .
You can use in that line if wants http request e.g:- let Run(req: HttpRequestMessage, log: ILogger) =
And make sure that your folder structure looks like below format:
FunctionsProject
| - MyFirstFunction
| | - run.fsx
| | - function.json
| | - function.proj
| - MySecondFunction
| | - run.fsx
| | - function.json
| | - function.proj
| - host.json
| - extensions.csproj
| - bin
