Preview 3 of .NET 8 includes a new project templates to create an API with a TODO service instead of the weather forecast .

This article looks into the changes coming.
Unhandled exceptions are a bit of a misnomer. In .NET, every exception is handled.

In short, when errors occur, .NET serves them up to your code in a neatly packaged, highly examinable data block.
ممنون از را حلی که ارائه دادین، اشکال مربوطه رفع شد... مهندس جان حین اجرای برنامه و بدون استفاده از StructureMap حین اجرای برنامه کانکشن استرینگ رو تغییر میدم و از دیتابیسی به دیتابیس دیگه ای میرم و با تغییر متغییر و پارامتر مورد نظر کاملا جواب میده ولی وقتی با استفاده از StructureMap و روشی که فرمودین عمل میکنم اجازه سوئیچ روی دیتابیس دیگه رو نمی‌ده وتغییری هم درکانکشن استرینگ جدید ارسال شده به Context مربوطه مشاهده نمی‌شه . کاربر حتما نیاز به تغییر سال عملیاتی حین اجرای برنامه و یا دسترسی به اطلاعات سال عملیاتی همتا رو بدون خروج از سال عملیاتی جاری داره....
