Azure Function项目的.Net7升级无法在本地运行

Question

我将 VS 2022 更新到最新版本，并将我的 Azure 函数项目升级到 .Net7。从 Visual Studio 运行应用程序时收到错误消息“没有与项目中指定的版本匹配的可用函数运行时。”。我该如何解决这个问题？请注意，它在 Azure 中运行良好。

另外，如果我尝试创建新的 Azure 函数项目，我不会将 .Net7 视为运行时选项。

Answer 1

当 .NET 7 在 Azure Functions Context 上的 Visual Studio IDE 中不可见时，请尝试检查控制面板 > 程序 > 程序和功能，所有内容均按预期安装，但仍未显示在 Visual Studio 2022 最新版本 IDE 中。

很高兴@frosty在VS Dev 社区文章# 10224478的帮助下解决了这个问题

1. 通常，可以通过删除%LocalAppData%\\AzureFunctionsTools并重新启动 Visual Studio IDE 查看是否有效来解决该问题。
\n
2. 如果这不起作用，请转到 VS IDE > 工具 -> 选项 -> 项目和解决方案 -> Azure Functions，然后单击“ check for updates”。然后下载并安装更新并查看是否有效。
