说明属性在DNX Core 5.0中不可用 [英] DescriptionAttribute not available in DNX Core 5.0

问题描述

我在ASP.NET 5项目中的DescriptionAttribute遇到了问题.

I'm having an issue with DescriptionAttribute in ASP.NET 5 project.

我想对enum类使用DescriptionAttribute，但是由于缺少DNX Core 5.0中的引用而无法构建该项目

I wanted to use DescriptionAttribute for my enum class, but the project cannot be built due to missing reference in DNX Core 5.0

这是我的project.json文件

推荐答案

System.ComponentModel.DescriptionAttribute在CoreCLR中不可用.

System.ComponentModel.DescriptionAttribute is not available in CoreCLR.

您有两个选择:

1. 找到它的替代品或自己实现.
2. 从project.json
中受支持的框架列表中删除dnxcore50(CoreCLR).

1. Find a replacement for it or implement it yourself.
2. Remove dnxcore50 (CoreCLR) from your supported framework list in project.json
