dotnet ef dbcontext info FileLoadException

Bug description

Hello,

I'm on M1 Mac with .NET 9 installed and when I try to run dotnet-ef I get a FileLoadException:

> dotnet ef dbcontext info
Build started...
Build succeeded.
Unhandled exception. System.IO.FileLoadException: Could not load file or assembly '/Users/dejan/.dotnet/tools/.store/dotnet-ef/9.0.10/dotnet-ef/9.0.10/tools/net8.0/any/tools/netcoreapp2.0/any/ef.dll'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
File name: '/Users/dejan/.dotnet/tools/.store/dotnet-ef/9.0.10/dotnet-ef/9.0.10/tools/net8.0/any/tools/netcoreapp2.0/any/ef.dll'

Everything is version 9:

> dotnet --version
9.0.100

> dotnet ef --version
Entity Framework Core .NET Command-line Tools
9.0.10

> cat ef.csproj
<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="9.0.10" />
  </ItemGroup>
</Project>

It seems weird that it's a 9.0.10 dotnet-ef but the DLL is in the net8.0 path.

Here are the contents of my directory:

Please try using 10.0.0-rc2 or newer

It won't install:

> dotnet tool install --global dotnet-ef --version 10.0.0-rc.2.25502.107
Tool 'dotnet-ef' failed to update due to the following:
The settings file in the tool's NuGet package is invalid: Settings file 'DotnetToolSettings.xml' was not found in the package.
Tool 'dotnet-ef' failed to install. Contact the tool author for assistance.

Thanks,
Dejan

You'd also need to install .NET SDK 10.0.100-rc.2.25502.107
