Visual Studio错误“未将对象引用设置为对象的实例"安装ASP.NET和Web Tools 2015之后 [英] Visual Studio error "Object reference not set to an instance of an object" after install of ASP.NET and Web Tools 2015

问题描述

安装ASP.NET和Web工具2015(RC1更新1)后，打开*.cshtml文件时，我在ASP.NET MVC 4项目中收到以下错误:

After installing the ASP.NET and Web Tools 2015 (RC1 update 1) I get the following error within ASP.NET MVC 4 projects when opening *.cshtml files:

对象引用未设置为对象实例

Object reference not set to instance of an object

即使我启动一个新的ASP.NET MVC 4项目并尝试在那里打开*.cshtml文件，我也会收到相同的错误消息.

I get the same error message even if I start a new ASP.NET MVC 4 project and try to open a *.cshtml file there.

我正在使用Visual Studio 2015

I'm using Visual Studio 2015

推荐答案

也许有帮助:

1. 从以下文件夹中删除内容:

1. Delete the contents from the following folders:

1. C:\ Users \％userprofile％\ AppData \ Local \ Microsoft \ VisualStudio
2. C:\ Users \％userprofile％\ AppData \ Local \ Microsoft \ VSCommon

有时，您需要转到:

Sometimes, you need to go to:

1. [x64] C:\ Program Files(x86)\ Microsoft Visual Studio 14.0 \ Common7 \ IDE
2. [x86] C:\ Program Files \ Microsoft Visual Studio 14.0 \ Common7 \ IDE

并运行devenv /resetuserdata.

预计，您的所有用户设置(例如Visual Studio布局，链接的Microsoft帐户或起始页)可能会消失.

Expect, that all of your user settings such as Visual Studio layout, linked Microsoft account or start page might disappear.
