5.Visual Studio 2017 15.9 منتشر شد
These are the customer-reported issues addressed in 15.9.5:
- VSX1000: No enough information has been provided to MSBuild in order to establish a connection to a Remote Server.
- Visual C++ 2017 Redistributable for ARM64 is not available via visualstudio.com.
- VC Runtime Redistributable Update for VS 15.9 deletes Registry Key. This fix may have an increased chance of requiring a reboot of the machine in order to install an updated VC++ Redistributable package.
- Incorrect codegen in managed c++ with List to List assignment.
- Can't connect to mac build host after Visual Studio 15.9.4 update.
- Resource directories missed in incremental builds with
AndroidAarLibrary
items. - Lots of external assembly references - JNI ERROR (app bug): local reference table overflow (max=512).
- The Unity Editor has been updated to 2018.3. For more information, please visit the Unity website.
- SSDT: We enabled SQL projects to build schemas that have non-clustered columnstore indexes on an indexed views.
- SSDT: We fixed a significant performance issue in the schema compare tool when generating a script.
- SSDT: We fixed the schema drift detection logic in the schema compare tool which forced a new comparison to reenable scripting and publishing actions.

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.
The Bosque programming language is designed for writing code that is simple, obvious, and easy to reason about for both humans and machines. The key design features of the language provide ways to avoidaccidental complexity in the development and coding process. The goal is improved developer productivity, increased software quality, and enabling a range of new compilers and developer tooling experiences.
FastEndpoints offers a more elegant solution than the Minimal APIs and MVC Controllers with the goal of increasing developer productivity. Performance is on par with the Minimal APIs and is faster; uses less memory; and outperforms a MVC Controller by about 34k requests per second on a Ryzen 3700X desktop.
