Localiser des pages de rasoir dans un autre assemblage

Question

Je souhaite trouver Mes pages de rasoir de projet dans un autre assemblage. pour ce faire, j'écrire le code suivant:

public void ConfigureServices(IServiceCollection services) 
{ 
    var adminAssembly = Assembly.Load(new AssemblyName("App")); 
    services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options => 
    { 
     var previous = options.CompilationCallback; 
     options.CompilationCallback = context => 
     { 
      previous?.Invoke(context); 

      context.Compilation = context.Compilation.AddReferences(
       MetadataReference.CreateFromFile(typeof(dodo).Assembly.Location)); 
     }; 
    }); 

    services.Configure<RazorViewEngineOptions>(options => 
    { 
     options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App"))); 
     options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App")); 
    }); 
} 

ma solution:

lors de l'exécution localhost:5000/SameTodo Après erreur Get:

One or more compilation references are missing. Ensure that your project is referencing 'Microsoft.NET.Sdk.Web' and the 'PreserveCompilationContext' property is not set to false.

pile:

The type or namespace name 'SameTodoModel' could not be found (are you missing a using directive or an assembly reference?) + public global::Microsoft.AspNetCore.Mvc.Rendering.IHtmlHelper Html { get; private set; } The type or namespace name 'SameTodoModel' could not be found (are you missing a using directive or an assembly reference?) + public global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData => (global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary)PageContext?.ViewData; The type or namespace name 'SameTodoModel' could not be found (are you missing a using directive or an assembly reference?) + public SameTodoModel Model => ViewData.Model; The type or namespace name 'SameTodoModel' could not be found (are you missing a using directive or an assembly reference?) + public global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary ViewData => (global::Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary)PageContext?.ViewData;

et définir PreserveCompilationContext à faux mais maintenant travaillé comment puis-je résoudre ce problème?

Answer 1

Avez-vous besoin d'une instruction @using dans votre _ViewImports.cshtml de WebApplication5? Comme @using App.SameTodoModel

Answer 2

Au lieu de newing AssemblyName, utiliser une référence d'un type de cette assemblée:

var adminAssembly = typeof(SameTodoModel).Assembly;

En outre, le message d'erreur dit: propriété 'PreserveCompilationContext' est pas définie sur false .

Cela signifie qu'il doit être défini sur true.

public void ConfigureServices(IServiceCollection services) 
{ 
    var adminAssembly = Assembly.Load(new AssemblyName("App")); 
    services.AddMvc().AddApplicationPart(adminAssembly).AddRazorOptions(options => 
    { 
     var previous = options.CompilationCallback; 
     options.CompilationCallback = context => 
     { 
      previous?.Invoke(context); 

      var referenceAssemblies = AppDomain.CurrentDomain.GetAssemblies() 
       .Where(x => !x.IsDynamic&& !string.IsNullOrEmpty(x.Location)) 
       .Select(x => MetadataReference.CreateFromFile(x.Location)) 
       .ToList(); 

      //add dynamic 
      var dynamicAssembly = typeof(DynamicAttribute).Assembly; 
       referenceAssemblies.Add(MetadataReference.CreateFromFile(dynamicAssembly.Location)); 

      context.Compilation = context.Compilation.AddReferences(referenceAssemblies); 
     }; 
    }); 

    services.Configure<RazorViewEngineOptions>(options => 
    { 
     options.FileProviders.Add(new EmbeddedFileProvider(Assembly.Load("App"))); 
     options.FileProviders.Add(new PhysicalFileProvider(@"C:\Users\soheil\Documents\Visual Studio 2017\Projects\WebApplication5\App")); 
    }); 
}
