System.ObjectDisposedException: Cannot access a disposed context instance.
A common cause of this error is disposing a context instance that was resolved from dependency injection and then
later trying to use the same context instance elsewhere in your application. This may occur if you are calling 'Dispose'
on the context instance, or wrapping it in a using statement. If you are using dependency injection, you should let the
dependency injection container take care of disposing context instances.
Object name: 'ApplicationDbContext'.

و ساختار سرویس که SSIS به این ساختار نیاز دارد .

حال از محیط BIDS یک پروژه SSIS ایجاد می‌کنیم (برای آشنایی با BIDS به این پست مراجعه کنید) و یک Web Service Task به آن اضافه می‌کنیم :

سپس روی task دوبار کلیک کنید تا پنجره تنظیمات آن باز شود :

حال باید یک دیتا سورس کانکشن که همان سرویس ما می‌باشد تعریف کنیم :

دکمه تست را فشار دهید تا تاییدیه معتبر بودن سرویس را دریافت کنید ، OK را فشار دهید .

در قدم بعد SSIS به قالب فایل xml که در خروجی WSDL است نیاز دارد . اگر این فایل را دارید آدرس آن را باید در قسمت WSDL FIle وارد کنید در غیر این صورت (مانند شرایط فعلی این مثال) باید این فایل را از سرویس خود دانلود کنید . نکته اینکه در صورتی که این فایل را ندارید ، گزینه overwriteWSDLFile را True کنید و مسیر یک فایلی که در سیستم شما موجود نیست را در آدرس WSDLFile وارد کنید . 

حال شما فایل مورد نظر را دارید :

اگر به تب input بازگردید می‌توانید ادامه تنظیمات را انجام دهید :

حال باید خروجی مورد نظر از این سرویس را تعریف کنیم . دو نوع خروجی برای ما امکان پذیر است . یکی انتقال اطلاعات به یک فایل (مناسب برای مواردی که نیاز به داده‌های offline دارید) و یکی منتقل کردن آنها به متغیر‌های خود SSIS Package برای استفاده در کام‌های بعدی flow (برای مواردی که نیاز به انجام تغییرات روی داده‌های Online دارید) .

پس از انجام این تنظیمات باید کانکشن هایی مطابق زیر داشته باشید :

F5 را فشار دهید تا عملیات شروع شود :

موفق باشید
