  3. build the app

Expected Behavior

no warnings in output

    @MagicAndre1981 can you share the exact <PackageReference/> you have in a .csproj that hits these warnings? Thanks.

    @MagicAndre1981 can you share the exact <PackageReference/> you have in a .csproj that hits these warnings?

      <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.SignalR.Client">
      <Version>3.1.20</Version>
    </PackageReference>
    <PackageReference Include="Microsoft.AspNetCore.SignalR.Protocols.Json">
      <Version>3.1.20</Version>
    </PackageReference>
    <PackageReference Include="Xamarin.Forms" Version="5.0.0.2125" />
    <PackageReference Include="Xamarin.Essentials" Version="1.7.0" />
  </ItemGroup>

    Repro steps are easy, create new XF app and add those 2 SignalR packages

    Still happens in VS 2022 17.1 Preview 3 with SignalR 6.0.1 references. Addding System.Numerics.Vectors directly via PackageReference Include makes no difference.

    I checked a new MAUI App in 17.1 Preview 3 and here the System.Numerics.Vectors 6.0.1 is used and I see no warning. So this is an "issue" with old xamarin.

    @MagicAndre1981 I'm afraid this issue probably won't be able to be solved until .NET 6. Do you have the problem in a dotnet new android or dotnet new maui app?

    with .net 6 it works fine. So this only happens in old classic xamarin.

    With support for Classic Xamarin.Android ended May 1st, 2024, this issue is likely no longer relevant.

    If this still persists in .NET 8+, please open a new issue with updated information based on net8.0-android or greater. Please include a link to this issue for context.
