RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out

WORKDIR /app
COPY --from=build-env /app/out .

ENTRYPOINT ["dotnet", "TgBotWorker.dll"]

This issue isn't related to library at all. In this line RUN dotnet publish -c Release -o out add --self-contained true and check info about self-contained apps and not. For issues like this you can ask in telegram chat. I will add full example below for Dockerfile:

FROM --platform=$BUILDPLATFORM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /source

# copy csproj and restore as distinct layers
COPY ["Project.csproj", "./"]
RUN dotnet restore -r linux-x64 "./Project.csproj"

# copy and publish app and libraries
COPY . .
RUN dotnet publish "./Project.csproj" -r linux-x64 -c Release --self-contained true --no-restore -o /app

# final stage/image
FROM mcr.microsoft.com/dotnet/runtime:8.0
WORKDIR /app
COPY --from=build /app .
ENTRYPOINT ["./Project"]

Please close this issue.

Ok, thanks, I'll try that.
But why is everything ok in my case with version 19.0.0? This problem appears starting with version 22

@flor3sc0 That's because since v21 it was added "Microsoft.Extensions.Options.ConfigurationsExtensions" dependency that requieres ASP.NET Core Runtime for work

I had the same problem, the solution was very simple.
Replace this:
FROM mcr.microsoft.com/dotnet/runtime:8.0
To this:
FROM mcr.microsoft.com/dotnet/aspnet:8.0
