System.Data.Common from a PCL project

[joshfree]

Posting on behalf of a customer report via nuget.org

I would really like to be able to reference System.Data.Common from a PCL project - however the >current NuGet package doesn't support PCL.
Would you consider adding support for PCL?
Otherwise, I am planning on implementing it in a separate repository - I'm looking at using Type >Forwarding based on approach here: http://stackoverflow.com/questions/21357321/handling-missing->types-in-pcl-with-real-types-existing-on-some-of-the-platforms

Not sure that this is really related to System.Data.Common. You can't reference any of our NuGet packages from a PCL, as long as you are talking about old "profile-based" PCL projects. You should be able to reference them just fine from a new PCL project. For example, a new PCL project targeting dnxcore50/net46 should be able to reference the System.Data.Common package.

Thanks @mellinoe that answers my question.

My current dilemma is that I really want to compile (and distribute) my custom ADO.NET provider as a PCL that can be used with xamarin projects (monotouch and monodroid) not just dnxcore50 + net46

As soon as I try to target anything beyond dnxcore50 + net46 from my PCL project, then I can no longer pull in System.Data.Common NuGet Package - so I can no longer compile my ADO.Net provider as a PCL!

So, unless you guys are going to bring System.Data.Common to MonoTouch and MonoDroid anytime soon (grin), I'll continue down the path of creating a portable version of System.Data.Common over here: https://github.com/dazinator/Portable.System.Data.Common - having copied large portions of your code over - I am hoping to add support for xamarin.

P.S Not sure if you are interested in checking this, but when I tested adding the System.Data.Common nuget package to a new PCL project targeting only dnxcore50 + net46 - it would only work with the "latest stable" version of the package. The "latest pre-release" version kept failing during the install and was rolled back.

I think this is the sort of thing that our ".NET Platform Standard" work is hoping to address, but until we have finalized our plans/work for that, and until the xamarin platforms have "opted in" to the new paradigm, then I think you will be limited to the platforms that we support explicitly in the packages currently. @ericstj / @davidfowl is that accurate (with regards to the .NET Platform Standard) ?

Regarding this:

I'm not exactly sure about that. Perhaps your version of NuGet needs to be updated, or something of that sort.

@chcosta after you change the targeting of this library with https://github.com/dotnet/corefx/issues/4802 can you update the package to add a folder for portable-a+b+c similar to https://github.com/dotnet/corefx/blob/master/src/System.Collections.Immutable/pkg/System.Collections.Immutable.pkgproj

The fix for this has been checked in and will be in the next package push.
