This 15-minute tutorial shows you how to create a basic .NET Core web application that retrieves data from the Oracle database with Oracle Data Provider for .NET (ODP.NET) Core.  

There are several situations where you need to manage row level security for your database:

• Multi-tenancy (SaaS)
• Role or claim based row level security
• Logical delete
• Enabled/Disabled data 

• TLS 1.0: The request was aborted: Could not create SSL/TLS secure channel.
• Task List with filter set to Entire Solution doesnt display tasks/todos when the file is closed.
• Fatal error C1001: An internal error has occurred in the compiler.
• VS 2019 Preview 1 - EF6 edmx file cannot be saved.
• vcruntime140.dll should be made available on Microsoft Symbol Server.
• Static Analyser, Custom Rule Set (C++) does not execute included default sets.
• VS2019 Preview: Azure Function publishing does not work.
• References window does not remember its position.
• Missing formatting option for pointers and references.
• Microsoft.TeamFoundation.Client, Version=15.0.0.0 assembly not found when create a new web project. 

Work in progress to add support for covariant return types to the .NET runtime. Soon we'll be able to override a virtual method returning `object` with a method returning `string`. Because of how array variance works, weird things might be possible in IL. 

class Base
{
    public virtual IntPtr[] Fun() => null;
}

// This is obvious pseude-code because C# won't let us introduce methods differing
// in return type. C# also requires to be explicit about "virtual" and "override".
// But IL... not so much.
class Derived : Base
{
    // overrides Base.Fun on 32bit platforms.
    public override uint[] Fun() => null;

    // overrides Base.Fun on 64bit platforms.
    public override ulong[] Fun() => null;
}

how WebAssembly is evolving to be more than something that is run on web browsers. With WASI, you can run any app that is compiled into a .wasm binary on any host. 

For .NET 6, we plan to no longer perform any form of harvesting to ensure that all assets we ship can be serviced. This means we're dropping anything older than:

• .NET Framework 4.6.1
• .NET Core 3.1
• .NET Standard 2.0 

we’re releasing a special Installer of Visual Studio Code for Java developers. The package can be used as a clean install or an update for existing environment to add Java or Visual Studio Code to your development environment.  

This is a "go live" release that can be used in production with the understanding that you will need to update to the final stable release once it is available.  

The HTTP protocol specification defines an ETag as the "entity value for the requested variant"  Another way of saying this is that the ETag is a token that can be associated with web resource 

Whilst the new configuration system sit unders the ASP.NET repository on GitHub, it doesn't actually have any dependency on any of the new ASP.NET components meaning it can also be used in your non .net core projects too.
