Contributing: Running tests instruction outdated

In the contribution guidelines this is mentioned:

Make sure the project builds and all tests pass on your machine by running the buildandtest.cmd script on Windows or buildandtest.sh on Linux/Mac.

Apparently now simply dotnet test is used?

Also:

Having a configured git client that converts line endings to LF. See here..

This is handled by .gitattributes now, isn't it?

从贡献指南开始，将文档中记录的 buildandtest.cmd/buildandtest.sh 命令与当前的 dotnet test 工作流进行比较。检查 .gitattributes 和仓库当前的构建说明，然后更新过时的测试和行尾指导，以便贡献者获得准确的步骤。
