[Bug] warning MSB3277: Found conflicts between different versions of "System.Numerics.Vectors" that could not be resolved #15046

Open nZeus opened 2 years ago

nZeus commented 2 years ago

Description

A few months ago we upgraded to the latest version of Xamarin.Forms, and since then we keep getting a warning MSB3277: Found conflicts between different versions of "System.Numerics.Vectors" that could not be resolved.

So far this seems to be a bug in Xamarin.Forms which, for some reason, references MonoAndroid v1.0: image

Steps to Reproduce

  1. Create a project that references Xamarin.Forms@5.0.0.2244 and any of these:
    • Prism.Plugin.Logging.Common@8.1.16
    • Refit@5.2.4
    • System.Net.Http.Json@5.0.0
    • IdentityModel@5.2.0
  2. Build the solution, check the Warnings tab

Expected Behavior

No warnings should be shown

Actual Behavior

MSB3277: Found conflicts between different versions of "System.Numerics.Vectors" that could not be resolved is there

MagicAndre1981 commented 2 years ago

this is an Xamarin.Android/Tooling issue, which I reported some time ago. With MAUI, which uses .net6 it no longer shows up.

nZeus commented 2 years ago

Unfortunately, many teams cannot upgrade to MAUI yet. Any plans to have this fixed for Xamarin, please?

MagicAndre1981 commented 2 years ago

I doubt this. In the apk I see the newer dll so it looks like it gets used and the apps work fine so far.

cedricaxel commented 1 year ago

I had the same problem, I solved it by: -put my solution in .net standard 2.1

nZeus commented 1 year ago

@cedricaxel I tried to reference the package manually, but it had no effect. I still get the warning. What exactly you did and what did you have to suppress? image

burcinsahin commented 1 year ago

I have exactly the same warning issue. (VS2022 Version 17.7.0) Common project is already .Net Standart 2.1. I tried manually referencing nuget package and other suggestions above but issue still exists.
