How to refer to console application projects in .NET Core 3.0

I have created 2 console projects using .NET Core 3.0 and I have removed program.cs file in the 2nd project and add that project as a reference project to 1st one.

While compiling, I am getting the error "Program does not contain a static 'Main' method suitable for an entry point".

Can anyone explain the how the referencing 2 projects works in C#?

The entry-point (aka Main) needs to exist in any console project (i.e. an exe). Normally in this scenario you would have:

• some library project
  • (has some code)
• some console project
  • references "some library project"
  • has an entry-point (Main)
  • (probably has some other code)

It sounds like you just want to make the first project a library project rather than a console project, which can be done by removing <OutputType>Exe</OutputType> from the csproj.
