ฉันกำลังพยายามกำหนดเส้นทางพื้นฐานของแอปพลิเคชันสำหรับเว็บแอป. Net ที่ฉันกำลังสร้าง ฉันได้รับข้อผิดพลาดในเครื่องมือสร้างการกำหนดค่า นี่คือข้อผิดพลาดที่ฉันได้รับ
DNX,Version=v4.5.1 error CS1061: 'ConfigurationBuilder' does not contain a definition for 'SetBasePath' and no extension method 'SetBasePath' accepting a first argument of type 'ConfigurationBuilder' could be found (are you missing a using directive or an assembly reference?)
ฉันสมมติว่าฉันจะได้รับข้อผิดพลาดเดียวกันสำหรับ.AddJsonFile()และ.AddEnvironmentVariables(). ฉันทำอะไรผิดหรือเปล่า? ฉันไม่ได้เพิ่มการอ้างอิงที่ถูกต้องให้กับ project.json ของฉันหรือไม่ ฉันได้แนบ startup.cs และ project.json ของฉัน
