【英文标题】：Azure Functions Swashbuckle: Failed to resolve assembly 'Microsoft.AspNetCore.Mvc.Core' during rebuild

【问题描述】：

我想将 OpenAPI 规范添加到我的 Azure Functions 应用。为此，我想使用AzureExtensions.Swashbuckle，因为它可以自动生成规范并通过 swagger-ui 显示它。

当我第一次通过nuget 安装软件包时，一切正常。规范是自动生成的，我可以通过swagger-ui查看。

一旦我重建我的项目/解决方案，它就不再构建。构建过程中提示如下错误信息：

我正在使用带有 .NET Core 3.1 的 AzureFunctions V3。

这是我的 .csproj 文件：

我已经删除了我的本地 .nuget 目录，清理了 nuget 缓存并更新了其他包，但没有运气。

【参考方案1】：

如果您将[FromQuery] 或任何其他属性添加到您的天蓝色函数“控制器签名”，它可能会发生。 您可以尝试删除[FromQuery] 属性。

你可以参考这个正在进行的 github issue 关于同样的问题。

【讨论】：

啊，我在其中一个函数中设置了 [FromBody] 属性。我只搜索了[FromQuery]。现在一切正常。谢谢。
