In dotnet5 (function v3) we could fetch the metadata from FunctionContext by calling functionContext.BindingContext.BindingData.TryGetValue("Metadata", out var meta); However dotnet 6 (v4) does not seem to have this option.
Can anyone help me out by providing the correct implementation for the new dotnet 6 (v4) functions

To use .net6 with Function V4 we need VS 2022 environment or VS CODE .
I have tried with one simple blobtrigger azure function running with .net 5 and it works fine to fetch the meta data.
using System;
using System.IO;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;
namespace testfuncapp
{
public static class Function1
{
[Function("Function1")]
public static void Run([BlobTrigger("test/{name}", Connection = "AzureWebJobsStorage")] string myBlob, string name,
FunctionContext context)
{
var logger = context.GetLogger("Function1");
logger.LogInformation($"C# Blob trigger function Processed blob\n Name: {name} \n Data: {myBlob}");
}
}
}
OUTPUT:- And the same code we have tried with .net 6 environment and its works fine as well.
To do that Open VS CODE and update the .csproj file with .net 6 and function runtime version to V4
Install Function runtime v4in your local .
NOTE: We need to install only one runtime version at our end.
Update .csproj file
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net6.0</TargetFramework>
<AzureFunctionsVersion>v4</AzureFunctionsVersion>
<OutputType>Exe</OutputType>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Storage" Version="4.0.4" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.2.0" OutputItemType="Analyzer" />
<PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.5.2" />
</ItemGroup>
<ItemGroup>
<None Update="host.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
<None Update="local.settings.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<CopyToPublishDirectory>Never</CopyToPublishDirectory>
</None>
</ItemGroup>
</Project>
And update the settings.json file to .net 6 and function runtime to V4 then save it .
And then use the command as below:
1- dotnet restore
2- dotnet build
3- func host start
