Logic app with custom code function app Sdk version issue

[petteripoyhtari]

Hi,

I noticed that we have old libraries in our custom code function app project. This function app is triggered by logic app.
When I updated the libraries I received tons of errors. I pinned down that when I update the
Microsoft.Azure.Functions.Worker.Sdk version 1.15.1 --> 1.16.0 I receive these errors immediately:

Piece of our custom code function app looks like this:

<ItemGroup> <PackageReference Include="CSharpier.MsBuild" Version="0.30.6"> <PrivateAssets>all</PrivateAssets> <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets> </PackageReference> <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Abstractions" Version="1.3.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.15.1" /> <PackageReference Include="Microsoft.Azure.Workflows.Webjobs.Sdk" Version="1.1.0" /> <PackageReference Include="Microsoft.Extensions.Logging.Abstractions" Version="5.0.0" /> <PackageReference Include="Microsoft.Extensions.Logging" Version="5.0.0" /> </ItemGroup>

What could be wrong? I have understood that custom code function apps can be picky of dependencies (like mentioned here https://learn.microsoft.com/en-us/azure/logic-apps/create-run-custom-code-functions#limitations "To avoid package references conflicts..."), but I can't quite understand how to pinpoint what dependencies could be needed to use little bit newer nugets? Or are we forever stuck for these older versions of libraries?
