Im running into an issue using docker and couldn't find a proper solution.
I'm trying to build a docker image using dotnet sdk 2.1.
The thing is that when docker tries to run the build statement, it fails and the error output is
CSC : error CS5001: Program does not contain a static 'Main' method
suitable for an entry point
The funny thing is that if i perform the buildd statement on command line locally, it works fine.
I have already checked my LanguageVersion tag on the project and it is 7.3.
here is my docker file
FROM microsoft/dotnet:2.1-sdk AS builder
WORKDIR /src
COPY ./nuget ./nuget
COPY ./NuGet.Config ./
COPY Services/AadTracking ./
# Copy all the referenced projects
COPY ./Services/AadTracking/Company/Company.Service.AadTracking/Company.Service.AadTracking.csproj ./AadTracking/Company/Company.Service.AadTracking/Company.Service.AadTracking.csproj
COPY ./Services/AadTracking/Office.Re.Service.AadTracking/Office.Re.Service.AadTracking.csproj ./AadTracking/Office.Re.Service.AadTracking/Office.Re.Service.AadTracking.csproj
