Still happens with:

Xamarin.iOS 14.14.2.5
and: System.Text.Json Nuget 5.0.0 and 5.0.1

Background info, because this was discussed in another thread.

Every Xamarin.iOS Release >= 12.16, is Netstandard 2.1 capable.

Keeping this open for now as tracking, but if it's a true dupe we can resolve.

ericstj · 2021-03-22T20:58:57Z

@juwens can you try this workaround:

<PackageReference Include="System.Memory" Version="4.5.3" IncludeAssets="None" />

That should confirm the issue and unblock you if necessary.

filipnavara · 2021-03-22T21:00:28Z

Actually, the version should be 4.5.4 (the highest version in NuGet; possibly referenced from other NuGets):

<PackageReference Include="System.Memory" Version="4.5.4" IncludeAssets="None" />

juwens · 2021-03-22T22:04:11Z

With IncludeAssets="None"

<PackageReference Include="System.Memory" Version="4.5.4" IncludeAssets="None" />

I get a build error

/Users/jjaehrig/repo/moonshot/src/FooApp/FooApp/App.xaml.cs(31,31): Error CS0012: The type 'ReadOnlySpan<>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Memory, Version=4.0.1.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. (CS0012) (FooApp)

juwens · 2021-03-22T22:10:58Z

While I'm currently creating a sample app, I noticed that I'm having trouble to reproduce the problem.
Maybe it's a combination of Nuget-Packages in our production app.

filipnavara · 2021-03-22T22:12:51Z

It's exactly the same error as the ones linked from dotnet/macios#10928. I do have a repro app, several of them in fact.

filipnavara · 2021-03-22T22:22:16Z

The triggering combination is usually a library that targets netstandard2.0 and references NuGet package System.Memory. This library can be a local one or a NuGet one. Once you include this library from Xamarin.Mac/iOS project it incorrectly overrides the built-in System.Memory.dll (version 4.0.99.0) with the one from the NuGet (version 4.0.1.1). The one from the NuGet is not meant to be used with Xamarin and causes errors at runtime for certain usage (but not always, some methods are self contained).

juwens · 2021-03-22T22:27:44Z

Thanks a lot :)

juwens · 2021-03-22T22:50:20Z

@filipnavara all of our shared libs are netstandard2.0

Do you have another hint where to look at? I'm somewhat lost.

I've greped for 4.0.1.1, but found only these entries in the deps.json

I guess binlog is good point to start, if the above are not helpful.

Looking for things like this?

and

ericstj · 2021-03-22T23:43:55Z

@juwens we understand what's going on and @filipnavara's fix should address this.

One thing that seems to happen (occured for me when I tried to reproduce this) was that Xamarin's ImplicitlyExpandDesignTimeFacades was not running and adding System.Memory to the build. You could workaround this by either adding <Reference Include="System.Memory" /> (what should happen after the fix) or by explicitly setting <_HasReferenceToSystemRuntime>true</_HasReferenceToSystemRuntime> property. I wasn't sure why Xamarin's ImplicitlyExpandDesignTimeFacades target wasn't running for me, as I would have expected it here. THat might be something to look at @filipnavara
