.NET Core example fails to compile

My settings:

• dotnet version: 2.1.302
• Expecto.Template::9.0.0

I just followed the instructions on REAME and I get a build failure. I think I’m missing something very simple.

Microsoft (R) Build Engine version 15.7.179.6572 for .NET Core

I’m not an experienced .NET developer, but the compilation order seems correct to me in ExpectoTest.fsproj:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <Compile Include="Sample.fs" />
    <Compile Include="Main.fs" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Expecto" Version="8.*" />
    <PackageReference Include="FSharp.Core" Version="4.*" />
    <PackageReference Include="YoloDev.Expecto.TestSdk" Version="0.*" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.*" />
  </ItemGroup>

  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.DotNet.Watcher.Tools" Version="2.*" />
  </ItemGroup>
</Project>

The issue is the Microsoft.NET.Test.Sdk.

It will add a new file into your build with a Main.

But you don’t want this synthesized main, you want to keep your own.

So add this to a PropertyGroup:

<GenerateProgramFile>false</GenerateProgramFile>

Perfect! It is working smoothly.

Thanks!
