Hi Abhith
How do we add icu-libs package in docker image which is built using microsoft/dotnet:2.2-aspnetcore-runtime not alpine? As I am getting error apk not found when I try to add in my dockerfile using microsoft/dotnet:2.2-aspnetcore-runtime

@djvickx APK stands for Alpine Linux package manager, it will not be available with non-alpine images. The image "microsoft/dotnet:2.2-aspnetcore-runtime" is based on Debian (correct me if I'm wrong), and it uses apt-get CLI command to install packages. Another thing to note is the icu-libs is an Alpine Linux package so you might want to find a similar package under Debian.

If you are facing issues, the easiest solution would be switching the image.

@abhith Thanks for the clarification I got it now. I have also found out a way from official documentation about how to set Invariant Globalization setting in .net core project file, will try it out and if it doesn't work then I ll shift to alpine image.

This worked for me whilst usingmcr.microsoft.com/dotnet/core/sdk:3.1
with mcr.microsoft.com/dotnet/core/aspnet:3.1-alpine
