i have place the binary correctly
9.0.100-alpha.1.23477.3

here is my csproj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
  </PropertyGroup>

</Project>

and here is nuget.config
<add key="dotnet9" value="https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet9/nuget/v3/index.json" />
visual studio version

is there anything else to use dotnet 9?

Had the same problem. Google led me here. VS 2022 17.8.0
SDK: 9.0.100-alpha.1.23564.26

adding a global.json with this seems to do the trick:

{
  "sdk": {
    "version": "9.0.100-alpha.1.23564.26"
  }
}

@osexpert there's a Visual Studio setting in tools->options->preview features that enables preview SDKs. By default, a preview SDK won't load into a stable version of Visual Studio. I think your global.json probably forced VS to do so when the setting would have as well.
