Hello Windows Insiders!

Today we are pleased to release a new Insider preview build of the Windows Server VNext Semi-Annual Channel edition.

 

What's New

 

Windows Server Core Container Images Are 20% Smaller

 

In what should be a significant win for any workflow that pulls Windows containers images, the download size of the Windows Server Core container Insider image has been reduced by 20%. This has been achieved by optimizing the set of .NET pre-compiled native images included in the Server Core container image. If you are using .NET Framework with Windows containers, including Windows PowerShell, use a .NET Framework image, which will include additional .NET pre-compiled native images to maintain performance for those scenarios, while also benefitting from a reduced size.

 

 

Available Content

 

  • Windows Server vNext Semi-Annual Preview Build 19008 The Server Core Edition is available in the 18 supported Server languages in ISO format and in VHDX format in English only.
    • Matching Windows Server Core App Compatibility FoD Preview

Symbols are available on the public symbol server – see Update on Microsoft’s Symbol Server blog post and Using the Microsoft Symbol Server.
