[Bug] Unable to use Microcharts.Forms 1.0-preview in Xamarin Forms app that uses a .NET Standard 2.0 library
Describe the bug Unable to use Microcharts.Forms 1.0-preview in .NET Standard 2.0 library
Which platform and version is this for? Android
To Reproduce Steps to reproduce the behavior:
- Install Microcharts.Forms 1.0-preview in your Xamarin Forms app
- Install Microcharts 0.9.5.9 in your .NET Standard 2.0 library
- At runtime, observe errors due to breaking changes between these two versions
Expected behavior I believe we need a 1.0-preview package for Microcharts
You don't need the Microcharts package, it's not 1.0 compatible. Going forward it's by platform
Interesting. So if I had shared code in a library and used that library on multiple platforms... now I have to either make copies of that code or abstract it away from the Microcharts types.
The idea is to keep things specific, I could make a common package if that would be beneficial.
I mean, it's up to you. I can see how you'd aim for the greater simplicity of a package per platform. On the other hand, those of us who support multiple platforms do benefit from having some common types we can use to consolidate code into a single place.
I don't want to isolate people who use the library like you do, I know there's a couple other people who do that as well, it's not a major deal to make a shared package and it won't break things for those who do have it setup like that.
@eman1986: just to check in on this, do you plan to update the preview with a shared package, or will things remain as they are?
Thanks.
Yes I do, been a little busy lately but I am planning on releasing another preview version soon.
Side note: when using microcharts newer than 0.8.4.1-pre, one cannot test with xamarin forms mocks anymore (because skia dropped the net framework assembly with 1.68.0). See this issue
This is, of course, no problem on a real device or in the simulator, but if you want to test headless with spec flow, for example, this is a show stopper.
If skia dropped it, then there's nothing I can do. I'm not going to downgrade a dependency over a failure to unit test.
You might be better off making a ticket with the skia team.
I am using Microcharts with QuestPDF in a WPF application. So, I settled on using the new Microcharts.Forms 1.0-preview package. However, when I installed the latest Visual Studio update, I ran into Xaml Compiler errors because Microcharts.Forms package references Xamarin.Forms. Apparently, with this update, it is no longer possible for a WPF project to reference Xamarin.Forms unless you set EnableDefaultXamlItems
to false in the project file (see https://github.com/dotnet/wpf/issues/6153).
I've reverted to the previous version's common package and is working for now. I wonder if there might be value in creating a Microcharts.Core
package that doesn't have any "viewers"? I think that could be a good fit for integration with QuestPDF and other scenarios?
I believe I took out wof support because it's an older framework of Microsoft and they have the uwp platform now, also I was trying to focus on the xamarin platform more than anything as that's our core demographic.
