调试 Xamarin Form SignalR 客户端 C# 时出现警告消息 "There was a conflict"

Question

每当我调试我的 Xamarin 表单（移动、C#、SignalR.Client）时，下面的消息总是弹出。这是我的客户端无法连接到 Asp.Net Core 中的集线器的原因吗？我的集线器无法正常工作。我一直在我的代码中发现错误，但这是我在我的代码中发现的唯一错误。我该如何解决这个问题？

Answer 1

.Net 6还没有发布，所以容易出错。此外，VS2022（预览版 3）更适合调试此问题，因为已创建环境以使用 .Net 6 的预览版。尝试从此处安装 VS2022 的预览版 3 - https://visualstudio.microsoft.com/vs/preview/

如@magicandre1981 所说，您的问题可能源于您在使用 Visual Studio 2019

时使用 .Net 6
