visual studio 2017允许编译APP，同时存在“当前上下文中不存在”错误 [英] visual studio 2017 allows APP to be compiled while there are “does not exists in the current context” error

问题描述

在以前的版本中，此类错误导致应用程序无法编译但新版本存在非常严重的问题

例如，此对象在上下文中确实不存在，但它未显示在构建错误列表中，并且应用程序正在运行而不会在按F5按钮时出现任何错误。当然，当调用ASP.net页面时应用程序抛出错误

但我希望visual studio能够显示错误并在我尝试运行时抛出异常像以前版本的应用程序

此外，intellisense错误非常烦人。为什么它们出现？这里如何显示数百个

下面安装的Visual studio完整版。这是一个干净的新安装

解决方案

嗨朋友，

我有过这样的经历，有数百个智能感知错误和0个构建错误。删除
.suo文件后，重新启动的VS 智能感知错误消失了。

* .soo是一个隐藏文件。

对于VS2017有同样的问题，所以你可以使用类似的解决方案：删除
.vs \ Solution name \v15.suo

 

祝你好运，

In previous versions, such errors were preventing application to get compiled but new one have very serious problems

For example this object really not exists in the context but it is not shown in build error list and application is running without giving any error when hit to F5 button. Of course the application throws error when that ASP.net page is called

But i would expect visual studio to show that error and throw exception when i try to run the application like previous versions

Moreover, intellisense errors are extremely annoying. Why they appear? Here how they are shown hundreds of them

full version of installed visual studio below. it is a clean new installation

解决方案

Hi friend,

I had this experience once, with hundreds of intellisense errors and 0 build errors. After deleting .suo file an restarting VS intellisense errors are gone.

*.suo is a hidden file.

For VS2017 has the same issue, so you can use similar solution: Delete .vs\SolutionName\v15.suo

Fletcher
