Programming Environment for TypeScript & Node.js
Kretes is a programming environment for TypeScript applications built on top of Visual Studio Code. It combines a web framework with an editor into an integrated, battery-included solution. 

JSON support has only been introduced in MySQL 5.7.8, but it is undoubtedly the feature that arouses most enthusiasm among MySQL users. 

@NgModule({
  imports: [CommonModule, RouterModule],
  exports: [], // components that are used in app.component.ts will be listed here.
  declarations: [], // components that are used in app.component.ts will be listed here.

export class CoreModule {

    if (core) {
      throw new Error("CoreModule should be imported ONLY in AppModule.");
    }

  exports: [CommonModule], // common and shared components/directives/pipes between more than one module and components will be listed here.
  /* No providers here! Since they’ll be already provided in AppModule. */

  static forRoot(): ModuleWithProviders {
    // Forcing the whole app to use the returned providers from the AppModule only.
    return {
      ngModule: SharedModule,
      providers: [ /* All of your services here. It will hold the services needed by `itself`. */]
    };

The winner in terms of serialize speed is again FlatBuffer which still has the lowest overhead, but you need to go through a more complex compiler chain to generate the de/serialization code. The new entry MemoryPack is second which is the newest serializer 

Improved the MSBuild selection logic. The standalone instance inside OmniSharp is now preferred over VS2017, with VS2019 given the highest priority. This ensures that .NET Core 3.0 works correctly. It is also possible manually provide an MSBuild path using OmniSharp configuration, which is then always selected. (omnisharp-roslyn#1541, PR: omnisharp-roslyn#1545)

    {
        "MSBuild": {
            "MSBuildOverride": {
                "MSBuildPath": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\MSBuild\\15.0\\Bin",
                "Name": "vs2017 msbuild"
            }
        }
    }

This repo is for experimentation and exploring new ideas that may or may not make it into the main dotnet/runtime repo.  

.NET Core 3.0 is supported with Visual Studio 2019 16.3 Preview 3 and Visual Studio for Mac 8.3, which were also released today.  

You might think, as a developer, that nothing but the best is good enough as a development database. You might be mistaken. There is a lot to be said for LocalDB, but Ed Elliott argues that every edition has its pros and cons, and you need to consider Cloud-based resources, VMs and Containerised databases too. There is a whole range of alternatives and how you choose depends on the type of database you are developing, but for Ed, LocalDB gets the five-star accolade
 

Performance is a feature of .NET. In every release the .NET team and community contributors spend time making performance improvements, so .NET apps are faster and use less resources. 

When you build ASP.NET Core applications and you plan on running your applications on IIS you'll find that the way that Core applications work in IIS is radically different than in previous versions of ASP.NET.
