I'm using this [Dockerfile](https://github.com/intersystems-community/pex-demo/blob/master/dotnet/Dockerfile) to build .Net Gateway with my PEX BS. It works fine. If I change the image reference [here](https://github.com/intersystems-community/pex-demo/blob/master/dotnet/Dockerfile#L9) to `store/intersystems/iris-community:2021.2.0.617.0` in line 8 (so update from 2020.2 to 2021.2) it fails to build with: KafkaConsumer.cs(4,20): error CS0234: The type or namespace name 'EnsLib' does not exist in the namespace 'InterSystems' (are you missing an assembly reference?) [/source/KafkaConsumer.csproj] KafkaConsumer.cs(9,34): error CS0246: The type or namespace name 'BusinessService' could not be found (are you missing a using directive or an assembly reference?) [/source/KafkaConsumer.csproj] On [this line](https://github.com/intersystems-community/pex-demo/blob/master/dotnet/Dockerfile#L17): RUN dotnet publish -c release -o /app Any idea why this might happen?
