I have recently tried to convert my PCL projects to .NET Standard. After ...
Hi Jan,
The SDK contains a PCL libarary which is compatible with .NET Standard. If you are using project.json you need add portable-net45+win8 to your import section e.g.
"frameworks": { "netstandard1.1": { "imports": [ "portable-net45+win8" ] } }If your are using .csproj you need add
<PackageTargetFallback>portable-net45+win8</PackageTargetFallback>
under your <Project> element.
Thanks,

Hi Greg,
Thanks for the fast reaction.
1) Start VS 2017 (Windows)
2) Create new project and select "Class library (Portable)" with the following profile: (NET 4.5.1, Xamarin.Android, Xamarin.iOS
3) Open properities of the just created project
4) Click "Target .NET Platform Standard" link (in my case .NETStandard1.2 is preselected so I keep it)
5) Manage NuGet Packages and try to add "Dropbox.Api"
Nothing is added and the output says:
Package Dropbox.Api 4.3.0 is not compatible with netstandard1.2 (.NETStandard,Version=v1.2). Package Dropbox.Api 4.3.0 supports:
- net45 (.NETFramework,Version=v4.5)
- portable-dnxcore50+net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=net45+wp80+win8+wpa81+dnxcore50)
- portable-net40+sl5+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile328)
One or more packages are incompatible with .NETStandard,Version=v1.2.
Package restore failed. Rolling back package changes for 'ClassLibrary1'.
If I try to switch to .NETStandard1.6 it is the same result:
Package Dropbox.Api 4.3.0 is not compatible with netstandard1.6 (.NETStandard,Version=v1.6). Package Dropbox.Api 4.3.0 supports:
- net45 (.NETFramework,Version=v4.5)
- portable-dnxcore50+net45+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=net45+wp80+win8+wpa81+dnxcore50)
- portable-net40+sl5+win8+wp8+wpa81 (.NETPortable,Version=v0.0,Profile=Profile328)
One or more packages are incompatible with .NETStandard,Version=v1.6.
Package restore failed. Rolling back package changes for 'ClassLibrary1'.

Hi Qiming,
Yes, this worked. Thank you! I thought this all should work automatically while adding the NuGet. I do not know that much about this area yet. Is there any documentation Dropbox & .NET Standard around where I can read more and also use it in the future when libs get updated?
Best regards
Jan
