[enricosada]

a dotnet new an f# console app who reference an dotnet new F# lib, restore => build => run

@dsyme@ncave can you please check if this fails for you (i cannot repro locally the bug).

How to test it:

• clone repo
• have bugged sdk in PATH
  and

cd test\EndToEnd
dotnet restore
dotnet test --filter "FullyQualifiedName=Microsoft.DotNet.Tests.EndToEnd.GivenFSharpShouldWork.AppWithLib"

if you want to see the test generated, before dotnet test

set DOTNET_TEST_PRESERVE_TEMP=1

and change

using(DisposableDirectorydirectory=Temp.CreateDirectory())

to

varDisposableDirectory directory =Temp.CreateDirectory();

the test failure will show the generated directory, so you can manually run the commands

Ok got it, fails if lib is netstandard instead of netcoreapp.

Unhandled Exception: System.MissingMethodException: Method not found: 'Void Lib.Say.hello(System.String)'.
at Program.main(String[] argv)

this is the repro case of error https://github.com/dotnet/cli/issues/6912 and https://github.com/dotnet/cli/issues/6863
and anyway a good scenario to test

[dsyme]

@enricosada Thanks!

[dsyme]

Approved (once the corresponding fixes dotnet/fsharp#3215 are integrated into Microsoft/visualfsharp and available here)

[cartermp]

👍 Thanks a bunch, @enricosada. Same as @dsyme, this is good pending the changes to VF#

@wli3 Looks like this is pending #6935, otherwise the test will always fail to compile.

[enricosada]

closing in favor of #6975 who target release/2.0.0-preview2 branch
