In this C# 8 tutorial, I am going to introduce a selection of currently planned features which will most probably end up in the final release. All of the C# 8 features are still early in development and are likely to change. 

DuoCode is an alternative compiler, powered by Microsoft® Roslyn, and integrated in Visual Studio.

It magically cross-compiles your C# 6.0 code into high-quality readable JavaScript code, enabling rapid development of web applications utilizing the extensive features of the C# language, the Visual Studio IDE, and the .NET Framework base class libraries. 

Jon P. Smith, author of Entity Framework Core in Action, explains what a multi-tenant app is and then digs into the things you need to do to make a multi-tenant app using ASP.NET Core with EF Core.

Welcome to EntityFrameworkTutorial.net. Here you will learn everything about Entity Framework in easy steps. It covers basic to expert level tutorials for all the features of Entity Framework with code snippets. Readers can also download sample project and the School database used in various tutorials. 

To configure an IIS 8.5 server running on Server Core, perform the following:

• Install the Web-Server role
  
• Install the Web-Mgmt-Service
  
• Enable Remote Management
  
• Set the WMSVC service to start automatically
  
• Create connection from Remote IIS Management Console  
  

In a Visual Studio Live! conference keynote Tuesday a couple of Microsoft program managers were on hand to discuss what's going on with .NET today and tomorrow, clearly signaling that .NET Core is the future of the ecosystem and that programmers should use it for all new development projects.  

In this post, we introduced the idea that not all performance optimisations need to be complex to implement. In this example, we optimised the ToUrl method of the NEST library by conditionally avoiding executing code we know would cause allocations.  

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.

Security Advisory Notices

• A remote code execution vulnerability exists in Visual Studio when the C++ compiler improperly handles specific combinations of C++ constructs.
