これはおそらく、Route Debugger が、変更または削除した古いルートがいくつかあることを示しており、(マシンを再起動しても) 消えないという事実に関連している可能性があります。スタック トレースは、かなり前に削除されたソース ファイルも参照しており、それ以降、アプリは新しい場所に移動され、クリーンアップされ、再構築されています。私は何が欠けていますか？
これが私のルート登録コードのすべてです：
// in Global.asax.cs:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default2", // Route name
"Api/{controller}/{action}/{id}", // URL with parameters
new { controller = "DataSource", action = "Index", area = "Api", id = UrlParameter.Optional } // Parameter defaults
);
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
// in ApiAreaRegistration.cs:
public class ApiAreaRegistration : AreaRegistration
{
public override string AreaName { get { return "Api"; } }
public override void RegisterArea(AreaRegistrationContext context)
{
// DataSources
// Tables
context.MapRoute(
"ListTables",
// example:
// /api/DataSources/DataSource/1/schemata/schema/dbo/tables
"Api/DataSources/DataSource/{dataSourceId}/schemata/{schemaName}/tables",
new
{
controller = "Tables",
action = "TableList",
schemaName = "dbo",
dataSourceId = "DefaultId"
}
);
// Schemata
context.MapRoute(
"Schema",
// example:
// /api/DataSources/DataSource/1/schemata/schema/dbo
"Api/DataSources/DataSource/{dataSourceId}/schemata/{schemaName}",
new
{
controller = "Schema",
action = "Schema",
dataSourceId = "DefaultId",
schemaName = UrlParameter.Optional
}

// // DataSources
