Orleans is a cross-platform framework for building distributed applications with .NET 

Firefox Developer Edition 44, released last week, includes a brand new memory tool to help you understand how your web applications are using and retaining memory.  

you should either use the using statement, or let the DI container handle disposing objects for you. For cases where that's not possible, ASP.NET Core provides two mechanisms you can hook in to: RegisterForDispose and IApplicationLifetime. 

Using new XAML tools with Visual Studio 2015

In the recent interview with Scott Hanselman, Roberta Arcoverde, Head of Engineering at Stack Overflow, revealed the story about the architecture of Stack Overflow. They handle more than 6000 requests per second, 2 billion page views per month, and they manage to render a page in about 12 milliseconds. We imagine they use a microservice solution running in the Cloud with Kubernetes. 

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.
