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.

For us, being a small team, sharing code and high performance was key to helping us make a successful app with the hybrid approach. To us, this was the right decision, as it allowed us to scale to all major platforms with only 1 engineer and 1 designer.  

Here are some of the reasons why nullable reference types are less than ideal:

• Invoking a member on a null value will issue a System.NullReferenceException exception, and every invocation that results in a System.NullReferenceException in production code is a bug. Unfortunately, however, with nullable reference types we “fall in” to doing the wrong thing rather than the right thing. The “fall in” action is to invoke a reference type without checking for null.
• There’s an inconsistency between reference types and value types (following the introduction of Nullable<T>) in that value types are nullable when decorated with  “?” (for example, int? number); otherwise, they default to non-nullable. In contrast, reference types are nullable by default. This is “normal” to those of us who have been programming in C# for a long time, but if we could do it all over, we’d want the default for reference types to be non-nullable and the addition of a “?” to be an explicit way to allow nulls.
• It’s not possible to run static flow analysis to check all paths regarding whether a value will be null before dereferencing it, or not. Consider, for example, if there were unmanaged code invocations, multi-threading, or null assignment/­replacement based on runtime conditions. (Not to mention whether analysis would include checking of all library APIs that are invoked.)
• There’s no reasonable syntax to indicate that a reference type value of null is invalid for a particular declaration.
• There’s no way to decorate parameters to not allow null. 

• Delete option is missing from solution explorer context menu in Xamarin Forms Android projects.
• Xamarin.Android: Can't select target framework 28 in Android Manifest settings.
• Could not load file or assembly 'Microsoft.VisualStudio.Web.PageInspector.Loader, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
• "There was an error running the selected code generator" when trying to create a new view.
• Android Berechtigungsliste ist leer-Android permission list is empty.
• Missing icons for .axml files in Visual Studio 2019.
• axml icons are not displayed.
• Visual Studio extensions may fail to install attempting to overwrite core NuGet files.
• C# switch statement on a constant expression may produce bad compiler errors.

Welcome to the inaugural post in this “30 Days of TDD” series. If you’ve never done Test Driven Development or aren’t even sure what this "crazy TDD stuff” is all about than this is the series for you 

شاید بارزترین تغییراتی که در این پنجره به چشم می‌خورد اضافه شدن Template‌های جدید باشد. البته نباید از ظاهر گرافیکی به سبک Metro چشم پوشی کرد. یکی از این Template‌ها Portable Class Library است. توسط این گرینه می‌توان dll‌های قابل استفاده در Windows، Windows Phone،  Silverlight و البته  XBox 360 ایجاد کرد.

  

 

 

Template جدید دیگری که در VS.NET 2012 اضافه شده است گروه مربوط به Visual Studio Light Switch است. توسط این گزینه امکان ایجاد برنامه‌های Light Switch، بدون نیاز به نصب Visual Studio Light Switch بصورت جداگانه، فراهم است و جهت توسعه این دسته از برنامه‌ها می‌توانید از VS.NET 2012 استفاده کنید.

 

ASP.NET is one of the most successful web application development frameworks by Microsoft. With every update, new and extended features are added that help developers deploy highly scalable and high-performance web applications.

When coupled with application monitoring and other performance tools, such as a profiler, ASP.NET becomes a powerful solution for building incredible apps.

Within the framework itself, there are myriad features to help you overcome common development challenges, do more with your apps, and boost performance.
