Ionide-vscode-fsharp: build.sh fails on Mac OS X (also build.cmd on Windows 10) with newly created console project

[oscarvarto]

I'm creating a new console project from scratch, by using vscode-ionide "F#: Create new Project".

After the project is succesfully created, I'm hitting https://github.com/ionide/ionide-vscode-fsharp/issues/498 that in turn redirects me to

• https://github.com/fsprojects/Paket/issues/2620

To put this out of the way, I'm renaming .paket/paket.exe to .paket/paket.bootstrapper.exe, then running ./build.sh again.
This time ./paket/paket.exe is downloaded and the build process starts.

However, the build is failing with the following output:

./build.sh                                                                               ✓  4620  13:04:29

The important part (I think):

Starting Target: Restore (==> InstallDotNetCLI)
dotnet restore
/Users/oscarvarto/gitRepos/fsharpWork/FSharpExercises/FSharpExercises/FSharpExercises.fsproj : error MSB4057: The target "Restore" does not exist in the project.
Running build failed.

[oscarvarto]

I have just confirmed the same error MSB4057: The target "Restore" does not exist in the project occurs in Windows 10.
The difference is that I am not hitting https://github.com/fsprojects/Paket/issues/2620 here (no need to rename paket.exe to paket.bootstrapper)

[oscarvarto]

Just verified that a new console project works OK on a Ubuntu 16.04 LTS installation. Have no idea why the difference :/

[alanmbarr]

The first time I got this kind of issue was a missing MSBUILD environment variable. The second time I got it was when I tried to use VS2017 version of msbuild with ionide.

@alanmbarr Thank you very much for giving me any clue.

I'll put some information about my Linux environment (the one that is working at the moment):

I will edit this later with more information on these environments:

• I have installed VS2017 15.3.5 in the Windows 2010 installation.
• I have installed latest Visual Studio for Mac in the Mac

[alanmbarr]

According to the ionide documents you must use the visual studio 2015 build tools for windows. msbuild tools for vs2017 will not work

[Krzysztof-Cieslak]

Try refreshing templates (F#: Refresh Templates command) and try create projects again, I believe we fixed those bugs in Forge some time ago.... Also latest Ionide update should contain latest templates, so I hope it's all fixed now.

[oscarvarto]

@Krzysztof-Cieslak Updating to latest Ionide-fsharp 3.2.0 solved the problem on both Mac OS X and Windows 10 for me.

I really appreciate your hard work on Ionide. At least for me, it provides me with a very important tool to work with F# crossplatform.

This represents for me (and I guess some others too) that F# is a more attractive choice for a general purpose programming language.
