从 ASP.NET Core View 引用 NET461 DLL 模型类型

Question

我有一个新的 ASP.NET Core RC2 构建如下：

.NET Framework 461 的 DLL 库中存储的模型
Web 是 MVC Core 1.0 完整框架 - 不是基于核心框架

当引用 DLL 库中的模型类型和运行项目时，出现以下错误：

An error occurred during the compilation of a resource required to process this request. Please review the following specific error details and modify your source code appropriately. Generated Code The type or namespace name 'Data' does not exist in the namespace 'ADMA.EWRS' (are you missing an assembly reference?) 23. public class _Views_Murad_Index_cshtml : Microsoft.AspNetCore.Mvc.Razor.RazorPage> The type or namespace name 'Data' does not exist in the namespace 'ADMA.EWRS' (are you missing an assembly reference?) 39. public Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper> Html { get; private set; } An error occurred during the compilation of a resource required to process this request.

添加 Razor 选项后解决，如下代码所示：

 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);
            //    };
            //});
