Could not find 'xxx.Program' specified for

问题:

I am having issues when building a dotnet core application inside a docker container. I am using dotnet core 2.2.

The setting for the project are: Output: Console App Startup Project: Web.Project

When running the command below inside the container:

RUN dotnet build "Web.csproj" -c Release -o /app

I get the error below:

Could not find 'Web.Program' specified for Main method [/src/Web/Web.csproj]

If the project is just an assembly (dll) everything works fine but I'm unable to run the web app.

Any ideas?

The solution to my problem was to remove the following line from my csproj file:

<OutputType>EXE</OutputType>

It seems like visual studio 2107 adds that tag when changing the output type. Once I removed that, I was able to build and publish inside a Docker Container and Windows.
