Question

安装新VS 2017 RC后，我遇到构建asnetcore应用程序的问题，这是我收到的错误：

MSB4131不支持“FilesWritten”参数 “GenerateRuntimeConfigurationFiles”任务。验证参数是否存在在任务上，它是一个可获取的公共实例属性。

这是我的.csproj文件：

Answer 1

启动任务管理器
结束所有现有的MSBuild任务。
重建您的项目。它应该工作得很好。

旁边。你的.csproj对我来说很好看;但是，看起来它的设置可以在两个不同的环境中运行，可能是console和aspcore 1.0

Answer 2

所以看起来这与多个具有不同msbuild工具版本的项目有关。

我的旧项目没有使用引用工具的新约定：ToolsVersion =“15.0”Sdk =“Microsoft.NET.Sdk.Web”......

一旦我改变它们以使用这个约定，一切都开始起作用了。
