Are you able to share more details like your Dockerfile? A .NET 6/8 application should either be published as self contained (can be deployed with most base images) or framework dependent (can be deployed only if the base image contains .NET 6/8 runtime).

I am using dotnet 7.

Below is my dockerfile:

Stage 1: Build the projects

FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build

WORKDIR /src

Copy the solution and project files

COPY . .

Restore dependencies for all projects

RUN dotnet restore UI_Core/UI_Core.csproj

RUN dotnet restore RCL_DepBuilder/RCL_DepBuilder.csproj

Build the projects

RUN dotnet build UI_Core/UI_Core.csproj -c Release -o /app/UI_Core

RUN dotnet build RCL_DepBuilder/RCL_DepBuilder.csproj -c Release -o /app/RCL_DepBuilder

Publish the projects to the /app directory

RUN dotnet publish UI_Core/UI_Core.csproj -c Release -o /app/UI_Core

RUN dotnet publish RCL_DepBuilder/RCL_DepBuilder.csproj -c Release -o /app/RCL_DepBuilder

Stage 2: Create the runtime image

FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS runtime

WORKDIR /app

Copy the published outputs from the build stage

COPY --from=build /app/UI_Core .

COPY --from=build /app/RCL_DepBuilder .

Expose necessary ports

EXPOSE 80

EXPOSE 443

Start the application

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

Can you add a step to your Dockerfile to print out the contents of the working directory, like RUN ls -la /app?
