更新 .Net Framework 版本(4.6.2 到 4.7.2)后无法评估

问题描述

我一直在从事的一个项目已从 .NET Framework 4.6.2 升级到 4.7.2.在构建时，在不是我的代码的文件中，我收到以下错误:

A project I have been working on was upgraded from .NET Framework 4.6.2 to 4.7.2. On build, in a file that is not my code, I get the following error:

我在项目属性的构建选项卡中也看到了同样的错误.

I also see the same error in the build tab of my project properties.

我不知所措-我已经搜索了错误，但结果是空的.有没有人遇到过和/或解决过这个问题?

I'm at a loss- I've searched for the error and am coming up empty. Has anyone encountered and/or resolved this before?

推荐答案

升级后您的构建工具似乎从 MSBUILD 更改为 Roslyn.Microsoft.Managed.Core.targets 是 Roslyn 目标文件.

Looks like after upgrading your build tool is changed from MSBUILD to Roslyn. Microsoft.Managed.Core.targets is Roslyn target file.

如果您安装了以下 Nuget 包:

if you have following Nuget packages installed:

• Microsoft.CodeDom.Providers.DotNetCompilerPlatform

• Microsoft.CodeDom.Providers.DotNetCompilerPlatform

Microsoft.Net.Compilers

Microsoft.Net.Compilers

那么可能是导致问题的原因.将 Microsoft.CodeDom.Providers.DotNetCompilerPlatform 升级到 2.x 并删除第二个.那应该可以解决问题.

Then possibly it's causing the issue. Upgrade the Microsoft.CodeDom.Providers.DotNetCompilerPlatform to 2.x and remove the second one. That should fix the issue.
