我正在尝试使用VS代码创建在OSX上运行的ASP.NET Core MVC测试应用程序.
当我访问默认的主页/索引(或任何其他我尝试的视图)时,我得到一个“查看未找到”异常.
当我访问默认的主页/索引(或任何其他我尝试的视图)时,我得到一个“查看未找到”异常.
这是启动配置
public void Configure(IApplicationBuilder app) {
// use for development
app.UseDeveloperExceptionPage();
app.UseDefaultFiles();
app.UseStaticFiles();
app.UseMvc( routes => {
routes.MapRoute(
name: "default",template: "{controller=Home}/{action=Index}"
);
});
}
而且我在Views / Home / index.cshtml中定义了视图,并且我在project.json中包含以下包
"dependencies": {
"Microsoft.NETCore.App": {
"version": "1.0.0-rc2-3002702","type": "platform"
},"Microsoft.AspNetCore.Razor.Tools" : "1.0.0-preview1-final","Microsoft.AspNetCore.Diagnostics": "1.0.0-rc2-final","Microsoft.AspNetCore.Mvc": "1.0.0-rc2-final","Microsoft.AspNetCore.Server.IISIntegration": "1.0.0-rc2-final","Microsoft.AspNetCore.Server.Kestrel": "1.0.0-rc2-final","Microsoft.AspNetCore.StaticFiles": "1.0.0-rc2-final","Microsoft.AspNetCore.Routing": "1.0.0-rc2-final"
},
最后,这是我得到的例外.
System.InvalidOperationException: The view 'Index' was not found. The following locations were searched:
/Views/Home/Index.cshtml
/Views/Shared/Index.cshtml

任何关于我可能会失踪的建议
解决方法
我发现这个丢失的一块.我最终在VS2015中创建了一个ASP.NET Core项目,然后比较差异.原来我从主页的WebHostBuilder中缺少.UseContentRoot(Directory.GetCurrentDirectory()).
加入后：
public static void Main(string[] args)
{
new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseStartup<Startup>()
.Build()
.Run();
}
然后我收到一个关于missingcompilationContext的异常.一旦在project.json中添加,我的视图显示正确.
"buildOptions": {
"preserveCompilationContext": true,"emitEntryPoint": true
},
