我尝试过更改框架，清理框架，但所有错误都不会消失.

I tried changing frameworks, cleaning it and all but this error doesn't go away.

推荐答案

您是否遵循任何特定文档来创建此应用?否则，您是否只是在VS中选择一个简单的Function并进行构建?我也可以为您尝试复制.通常，您看到的错误与某些依赖性未正确加载有关 或正在安装. 

Are you following any specific documentation to create this app? Else are you just selecting a simple Function in VS and building it? I can attempt a repro for you as well. Generally the error you are seeing has to do with some dependency not loading properly or being installed.
