How to migrate Azure Functions v3 to .net core 5.0

I have upgraded all assemblies in an Azure Function v3 project to version 5.0 but I am unable to run the function. Here it is my function's csproj file's partial definition:

<PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <AzureFunctionsVersion>v3</AzureFunctionsVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.Functions.Extensions" Version="1.1.0" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.Storage" Version="4.0.3" />
    <PackageReference Include="Microsoft.NET.Sdk.Functions" Version="3.0.11" />
    <PackageReference Include="Microsoft.Azure.WebJobs.Extensions.SignalRService" Version="1.2.2" />
    <PackageReference Include="System.Net.Http" Version="4.3.4" />
  </ItemGroup>

What's the necessary workaround to make this function with .NET 5? Google did not yield anything conclusive.

Further info: 5.0.100 [C:\Program Files\dotnet\sdk]

This is one of the error messages that I get:

Could not load file or assembly 'Microsoft.Extensions.Configuration.Abstractions, Version=5.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

Dave Brock created a web page explaining the process using the preview bits. But I believe it should be close enough for the release bits. See here.

Looks like Brandon Minnick's guide is more comprehensive. See here.

Azure functions team released support for .Net 5 by introducing a new isolated process model to run .NET function apps.

You can read more about this in the announcement.

The comment by @Marc is correct, currently Azure Functions do not support .net 5. Current ETA is a preview by end of year.

Please keep an eye on this github issue for any updates.
