Invalid F# template when dotnet new
See original GitHub issueSteps to reproduce
dotnet new console -lang F#
dotnet build
Expected behavior
Build should pass. When F# compilation items should be either not listed or there should be <EnableDefaultCompileItems>False</EnableDefaultCompileItems>
. My vote is for the latter, because order of compiled files is important in F#.
Actual behavior
This is the generated fsproj
$ cat example.fsproj
<Project Sdk="FSharp.NET.Sdk;Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp1.1</TargetFramework>
</PropertyGroup>
<ItemGroup>
<Compile Include="Program.fs" />
</ItemGroup>
<ItemGroup>
<PackageReference Include="FSharp.Core" Version="4.1.*" />
<PackageReference Include="FSharp.NET.Sdk" Version="1.0.*" PrivateAssets="All" />
</ItemGroup>
</Project>
And build failure:

@tomzo @petertiedemann you miss the
dotnet restore
step.for more info about f# see wiki https://github.com/dotnet/netcorecli-fsc/wiki/.NET-Core-SDK-1.0.1
@tomzo as a note,
EnableDefaultCompileItems
is added already byFSharp.NET.Sdk
But because there was not dotnet resto, it was not addedif you get more issues, please fill in https://github.com/dotnet/netcorecli-fsc/issues
@piotrpMSFT this can be closed.
@Fedreg the new sdk 1.0 released some days ago now will show two warnings (if fsharp.net.sdk is not added/restored as package ref) and an error if restore is not done (the
obj/project.assets.json
doesnt exists), with a more clear message about “you forgot restore”
