Package 1.0.6.3 install fails for UWP App

[fgoulet]

In a new blank UWP App with Microsoft.NETCore.UniversalWindowsPlatform 5.1.0, I got a lot of downgrade warnings and this error:
System.Reflection.Emit.ILGeneration 4.0.1 provides a compile-time reference assembly for System.Reflection.Emit.ILGeneration on UAP,Version=v10.0, but there is no
run-time assembly compatible with win10-x86-aot.

When I bump the version to Microsoft.NETCore.UniversalWindowsPlatform 5.2.0, the downgrade warnings are gone but still the same error.

If possible, create an example app. With and without references to system.linq.dynamic.core

And also checkout my example project https://github.com/StefH/System.Linq.Dynamic.Core/tree/master/test-uap/UniversalWindowsApp and see the differences.

With Microsoft.NETCore.UniversalWindowsPlatform 5.1.0, my app works fine just like your example project. I tried to upgrade your example project to 5.2.0 and I got the same error. I need to upgrade my app to 5.2.0 in order to use EFCore 1.0 RTM. Could you try to upgrade your example app to Microsoft.NETCore.UniversalWindowsPlatform 5.2.0 ?

[fgoulet]

I forgot to mention that I have added System.Linq.Dynamic.Core project to the solution of my app to make it works with 5.1.0, like your example project.

Ok. Enough details I think. Thanks for this analysis. I'll take a look in some days.

Strange error, maybe no related to this library but see also

NuGet/Home#3034
dotnet/efcore#4802

AutoMapper seems to had the same problem and apparently were able to fix it
Can't install Automapper 5.0 into Windows 10 UWP #1448

In Automapper I think this was the fixing commit:LuckyPennySoftware/AutoMapper@f3e345d

[StefH]

By replacing some dependencies for .NetStandard by the "NETStandard.Library": "1.6.0" dependency ?

[jogibear9988]

Don't know. I only found this commit. I don't use UWP

[fgoulet]

I think the commit mostly remove the code for .Net Core that depends on ILGeneration. I have removed the aot runtimes (ahead of time) from my project.json of my UWP app and I can now successfully install package 1.0.5. I won't be able to build my app for .Net Native but at least I can pursue the development until a compatible version of system.Reflection.Emit.ILGeneration (hopefully!) comes up.

Hi!
Same thing here. Blank UWP App (either with .NETCore 5.1.0 or 5.2.2).
Can't install nuget package.
A lot of downgrade warnings and incompability errors with win10-arm-aot, win10-x64-aot and win10-x86-aot from System.Reflection.Emit.ILGeneration 4.0.1

[StefH]

Can somebody point me in some direction how to solve this?

[fgoulet]

Until there is a version of System.Reflection.Emit.ILGeneration compatible with the aot runtimes (.Net Native), I don't see what can be done.
