我有一个简单的.NET Core项目(控制台应用程序)，正在try 编译和运行.dotnet build成功，但在执行dotnet run时出现以下错误:
λ dotnet run
Project RazorPrecompiler (.NETCoreApp,Version=v1.0) was previously compiled. Skipping compilation.
A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in [path].
我的项目.json如下所示:
{
"buildOptions": {
"warningsAsErrors": true
},
"dependencies": {
"Microsoft.AspNetCore.Razor": "1.0.0",
"Microsoft.NETCore.App": {
"type": "platform",
"version": "1.0.0"
}
},
"description": "Precompiles Razor views.",
"frameworks": {
"netcoreapp1.0": {
"imports": [ ]
}
},
"version": "1.2.0"
}
什么是hostpolicy.dll，为什么它不见了？
