FileNotFoundException when using Serilog.Settings.Configuration in an Azure Function in .NET 6

[fgheysels]

I created an Azure Function which is running on .NET 6. My Azure Function uses Serilog for logging and I'm using Serilog.Settings.Configuration to read log settings from the configuration.

When running the Function, I run into this exception:

System.IO.FileNotFoundException: 'Could not load file or assembly 'Microsoft.Extensions.DependencyModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.'

I do see that the Serilog.Settings.Configuration package has a dependency on Microsoft.Extensions.DependencyModel v3.0.0.0 but this might maybe conflict with .NET 6 ?

I have worked around this for now by:

• explicitly adding a dependency on the package Microsoft.Extensions.DependencyModel v6.0.0
• specify this Property in my Function's csproj file:

     <PropertyGroup>
      <_FunctionsSkipCleanOutput>true</_FunctionsSkipCleanOutput>
  </PropertyGroup>

Hi @fgheysels , workaround seems enough. Dup #294

[fgheysels]

It's a workaround but not a clean solution imho.

It seems not work any more on latest dotnet tools. Can anyone confirm?

It's a workaround but not a clean solution imho.

If I'm not mistaken, isolated Functions should solve this issue ?

@krzysiek-b I've tested today and it still working
