Built-in support of docker has generated dockerfile with errors

My VS 2019 genereted Dockerfile with the next code:

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80

FROM mcr.microsoft.com/dotnet/core/sdk:3.1 AS build
WORKDIR /src
COPY ["src/Services/ProductCatalogApi/ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]
RUN dotnet restore "src/Services/ProductCatalogApi/ProductCatalogApi.csproj"
COPY . .
WORKDIR "/src/Services/ProductCatalogApi"
RUN dotnet build "ProductCatalogApi.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "ProductCatalogApi.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ProductCatalogApi.dll"]

And when I run my Dockerfile with command docker build . i receved next:

Sending build context to Docker daemon  77.49MB

    <PackageReference Include="Swashbuckle.AspNetCore" Version="5.5.1" />
  </ItemGroup>


</Project>

src/Services/ProductCatalogApi/ProductCatalogApi.csproj

does not exists from the folder you are running it from.

If the dockerfile is in the same folder as csproj, then it should be

COPY ["ProductCatalogApi.csproj", "src/Services/ProductCatalogApi/"]

It's a bit tricky then, if you are using docker-compose, the path has to be relative path to the docker-compose file you are trying to run
