Design patterns are typical solutions to common problems in software design. Each pattern is like a blueprint that you can customize to solve a particular design problem in your code
In an attempt to correct many perceived deficiencies in Entity Framework Core, Microsoft is introducing 40 breaking changes to EF Core 3. You can see the entire breaking changes list on Microsoft Docs, but here are some of the highlights.
Taylor Mullen shows us how to create custom Tag Helpers. The TagHelper that was added in the show was the Markdown TagHelper. It enables you to write Markdown in your Views.
- Linux support for tier-1, mission-critical workloads – SQL Server 2017 support for Linux includes the same high availability solutions on Linux as Windows Server, including Always On availability groups integrated with Linux native clustering solutions like Pacemaker.
- Graph data processing in SQL Server – With the graph data features available in SQL Server 2017and Azure SQL Database, customers can create nodes and edges, and discover complex and many-to-many relationships.
- Adaptive query processing – Adaptive query processing is a family of features in SQL Server 2017 that automatically keeps database queries running as efficiently as possible without requiring additional tuning from database administrators. In addition to the capability to adjust batch mode memory grants, the feature set includes batch mode adaptive joins and interleaved execution capabilities.
- Python integration for advanced analytics – Microsoft Machine Learning Services now brings you the ability to run in-database analytics using Python or R in a parallelized and scalable way. The ability to run advanced analytics in your operational store without ETL means faster time to insights for customers while easy deployment and rich extensibility make it fast to get up and running on the right model.
Asp.Net Core WebSockets Vs SignalR. Which should you use? (Full Course)
In this video we build 2 separate chat applications, one using Asp.Net Core WebSockets and the other using SignalR, allowing you to compare approaches and decide on which one works best for you. In both cases we build them with C#, .NET Core and JavaScript. You’ll also learn about:
- .NET Core Request Pipeline
- Request Delegates
- Asynchronous Programming in .NET (Async / Await)
- Introduction to Dependency Injection
This is another post in our Code Health series. A version of this post originally appeared in Google bathrooms worldwide as a Google Testing on the Toilet episode. You can download a printer-friendly version to display in your office
All the features are described in wonderful detail in the docs. Start with the overview, What’s new in C# 7.2, which gives you an excellent introduction to the new set of capabilities.
من با EF6 از
modelBuilder.Types().Configure(c=>c.Ignore("IsDeleted")); استفاده کردم ولی خطای زیر رو میگیرم:
You cannot use Ignore method on the property 'IsDeleted' on type 'MyEntity' because this type inherits from the type 'BaseEntity' where this property is mapped. To exclude this property from your model, use NotMappedAttribute or Ignore method on the base type.
The Blazor component model to be included in ASP.NET Core and shipped with .NET Core 3.0 was given the new name "Razor Components" to differentiate it from the ability to run .NET in the browser, Roth said.
با سلام،
برای styleهای inline هم باید از WithHash256 استفاده کرد؟
در یکی از پروژه‌ها متاسفانه inline Style زیاد استفاده شده و بنابراین پس از اجرای پروژه تمامی صفحه به هم می‌ریزد. با استفاده از developer tools هش‌های متعددی مانند پیغام خطایی که شما مثال زدید نمایش می‌دهد. بر آن شدم که تمامی هش‌ها را توسط WithHash256 وارد کنم اما بازهم نتیجه منفی بود و خطای صادر شده تمامی هش هایی که اضافه شده بودند را نیز در لیست می‌آورد.
بنابراین فعلا برای قسمت style از UnsafeInline استفاده کردم. آیا برای styleها می‌شود کار دیگری انجام داد؟
Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self' <URL> <URL>". Either the 'unsafe-inline' keyword, a hash ('sha256-e89EFOm4894OkHmgoH52lEUIFeaK8fITnql0='), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.
