.NET Framework example project does not build

[brad-bodily-gallagher-com]

Upon cloning the repo and trying to build the test_integration\Websocket.Client.Sample.NetFramework project (linked as the .net framework sample in the readme), dotnet build produces the following output, stating that Websocket.Client.csproj cannot be referenced by the framework example project.

dotnet build
Restore complete (0.5s)
  Websocket.Client.Sample.NetFramework failed with 1 error(s) (0.0s)
    C:\Program Files\dotnet\sdk\9.0.303\Microsoft.Common.CurrentVersion.targets(1890,5): error : Project '..\..\src\Websocket.Client\Websocket.Client.csproj' targets 'netstandard2.1;net6;net7;net8'. It cannot be referenced by a project that targets '.NETFramework,Version=v4.7.1'.

Build failed with 1 error(s) in 0.9s

Steps to reproduce

1. Clone the repo
2. Navigate to the test_integration\Websocket.Client.Sample.NetFramework directory
3. Run dotnet build

after version 5.0 of this library, it dont targets anymore to .net standard 2.0, so no more support for .net framework. i think README needs a update

.NET Framework support is back! Release
