Question

我有一个新的ASP.NET Core RC2，如下所示：

存储在.NET Framework 461的DLL库中的模型
Web是MVC Core 1.0 Full Framework - 不基于核心框架

当引用DLL库中的模型类型并运行项目时，我收到以下错误：

编译所需资源时发生错误处理此请求。请查看以下特定错误详细说明并适当修改源代码。生成的代码类型或命名空间名称＆＃39;数据＆＃39;在命名空间中不存在＆＃39; ADMA.EWRS＆＃39; （你错过了一个程序集引用吗？） 23. public class _Views_Murad_Index_cshtml：Microsoft.AspNetCore.Mvc.Razor.RazorPage＆gt; 类型或命名空间名称＆＃39;数据＆＃39;在命名空间中不存在＆＃39; ADMA.EWRS＆＃39; （你错过了一个程序集引用吗？） 39. public Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper＆gt; Html {get;私人集;编译期间发生错误处理此请求所需的资源。请查看遵循特定的错误详细信息并修改您的源代码适当。生成的代码类型或命名空间名称＆＃39;数据＆＃39;不命名空间中不存在＆＃39; ADMA.EWRS＆＃39; （你错过了一个集会吗？参考？） 23. public class _Views_Murad_Index_cshtml：Microsoft.AspNetCore.Mvc.Razor.RazorPage＆gt; 类型或命名空间名称＆＃39;数据＆＃39;在命名空间中不存在＆＃39; ADMA.EWRS＆＃39; （你错过了一个程序集引用吗？） 39. public Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper＆gt; Html {get;私人集; }

将Project.json配置如下：

添加Razor选项后解决，如下面的代码：

 services.AddMvc().// Murad Add this for RC2, remove it if release 1.0 after June 
                AddRazorOptions(options =>
            {
                var previous = options.CompilationCallback;
                options.CompilationCallback = context =>
                {
                    previous?.Invoke(context);
                    context.Compilation = context.Compilation.AddReferences(Microsoft.CodeAnalysis.MetadataReference.CreateFromFile(typeof(ADMA.EWRS.Data.Models.Murad).Assembly.Location));
                };
            });

            //var myAssemblies = AppDomain.CurrentDomain.GetAssemblies().Select(x => Microsoft.CodeAnalysis.MetadataReference.CreateFromFile(x.Location)).ToList();
            //services.Configure((Microsoft.AspNetCore.Mvc.Razor.RazorViewEngineOptions options) =>
            //{
            //    var previous = options.CompilationCallback;
            //    options.CompilationCallback = (context) =>
            //    {
            //        previous?.Invoke(context);

            //        context.Compilation = context.Compilation.AddReferences(myAssemblies);
            //    };
            //});
