当在Google App Engine flexible上运行.net core 3.1服务时，我周期性地收到一系列错误，这些错误表面上与服务调用无关：

• “未找到指定的框架'microsoft.AspNetCore.App'版本'2.1.1'。”
• 发现了以下框架：
• [/ usr / share / dotnet / shared / microsoft.AspNetCore.App]中的3.0.1

这些错误大约每3-4分钟记录一次-无论是否调用该服务。

开发和运行时：

• 带有1个webapi服务项目（/ api / values）和docker-compose项目的Windows上的Visual Studio 2019
• .Net Core 3.1
• Docker linux容器
• Google App Engine灵活

我已经阅读了几篇有关此类错误的文章，但就我而言，我没有任何2.1.1参考或代码。我的目标是.net core 3.1。我该如何解决？

当我在本地“ dotnet运行”或“ docker运行”时，不会发生错误。它们仅出现在GAE环境中。 GAE是否依赖2.1.1？还是“不支持3.1.1”

我曾尝试针对Multipe框架，但这在应用程序中造成了各种参考问题。无论如何，该服务都能正常运行。另一方面，查看错误日志的同事会将其用作解决与服务相关的任何和所有问题的替罪羊。

解决方案，dockerfile或GAE中的问题也是吗？
