从 ASP.NET Core 视图中引用 NET461 DLL 模型类型

Question

我有一个新的 ASP.NET Core RC2 构建如下：

• 模型存储在 .NET Framework 461 的 DLL 库中
• Web 是 MVC Core 1.0 完整框架 - 不基于核心框架

引用DLL库中的模型类型并运行项目时，出现以下错误：

配置 Project.json 如下：

在添加 Razor 选项后解决，如下代码：

 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);
            //    };
            //});
