As a relatively new framework, there's probably a lot you don't know about Blazor yet. Here are 10 great features about Blazor you should know. 

These are the customer-reported issues addressed in 15.8.3:

• Visual Studio 2017 version 15.8.2 contained a pre-release build of .NET Core SDK 2.1.401 that is incompatible with Visual Studio. We have corrected this issue with Visual Studio 2017 version 15.8.3.
• VSCppUnit test case creation failure.
• Python IntelliSense not working on Python 2.7.
• XAML designer causing Visual Studio to close unexpectedly. 

Here is a partial list of the C# coding standards my team uses and advocates, updated by what we’ve learned in the past year. 

The .NET Framework 4.7 includes improvements in several areas:

ابتدا باید فرآیند نصب را انجام دهید:

* خط به خط کد‌های زیر را، در cmd و پشت سر هم اجرا کنید

(نکته): باید پایتون را از قبل نصب داشته باشید (آموزش نصب پایتون)

حالا اگر cmd شما در همچین مسیری قرار دارد:

میتوانید دستوری که در متن مقاله ذکر شده را اجرا کنید (البته با اندکی تغییر):

فایل کامپایل شده e_sqlite3.o رو در پروژه خود کپی کنید و طبق مقاله پیش بروید  و این فایل نیتو را به پروژه رفرنس بدهید.

اکنون اگر دستور dotnet bulid را در ترمینال بزنید،  احتمالا با همچین هشداری مواجه خواهید شد:

در صورت مشاهده همچین هشداری و حل این مشکل (اضافه نشدن فایل نیتیو به برنامه) ابتدا 

را به قسمت بالای فایل csproj خود و در قسمت 

اضافه کنید و سپس دستور زیر را اجرا کنید:
