How to migrate 1.0 projects to 2.0

The FSharp.NET.Sdk used in sdk 1.0 was deprecated in favor of including the F# sdk needed inside Microsoft.NET.Sdk.

There are some little behaviour changes, see the Summary below, but not much developer side.

The dotnet new templates are up to date, can be used as examples for all templates.

Summary of changes from 1.0 to 2.0

These are not all changes of sdk 2.0, but only these specific for F#

FSharp.NET.Sdk is deprecated, just remove it
the fsc f# compiler used is not from FSharp.Compiler.Tools package but the fsc is bundled with the various sdk (vs/cli/mono)
FSharp.Core package is added implicit as version 4.2.*

About FSharp.Core v4.2 implicit used (more info in F# RFC FS-1034)

is now published by Microsoft instead of F# Software Foundation
doesnt depend on System.ValueTuple package (unlike 4.1) but that is added as implicit PackageReference by sdk for some target framework in .fsproj
some target framework profiles are removed (see FSharp.Core v4.2.1 release notes ), the net45 and netstandard1.6 remains
is now built and packaged from Microsoft Visual F# repository instead of F# Software Foundation fsharp/fsharp repository

The FSharp.NET.Sdk in Sdk and as PackageReference is not required anymore, and should be removed.

remove FSharp.NET.Sdk from Sdk attribute of Project

from

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

to

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

remove the PackageReference

<PackageReference Include="FSharp.NET.Sdk" Version="1.0.*" PrivateAssets="All" />

The FSharp.Core package is now added as implicit package. That mean, by default, exists an implict

<PackageReference Include="FSharp.Core" Version="4.2.*" />

Two options for migration:

or remove the exists PackageReference (by default of FSharp.Core 4.1.*) and use implicit 4.2.*
or disable the implicit add of 4.2.* and continue to use the previous specified version (as PackageReference or by Paket) by adding a property

<DisableImplicitFSharpCoreReference>true</DisableImplicitFSharpCoreReference>
