Visual Studio 2017 15.8, meanwhile, will see the asynchronous background auto loading of extensions delayed until after Visual Studio startup and solution load are completed.  

A high-performance second-level query cache for EF Core.  Nuget Package

Using Example 

dbContext.Books
   .Include(d => d.Pages).ThenInclude(d => d.Lines).Where(d => d.ID == 200)
   .Cacheable(TimeSpan.FromSeconds(60))

Performance Test  

Cacheable vs DataBase

Average database query duration [+00:00:00.0026076].
Average cache query duration [+00:00:00.0000411].
Cached queries are x63 times faster. 

Cacheable vs In-Memory

Average database query duration [+00:00:00.1698972].
Average cache query duration [+00:00:00.0000650].
Cached queries are x2,611 times faster. 

thanks to a new feature added in Visual Studio 2019 16.1, we can combine the best of both worlds when it comes to support the App Installer technology: the easiness of automatically generating an .appinstaller file as part of the package creation process and the flexibility of the new update features added in Windows 10 1903. 

Today, we are releasing .NET 5.0 Preview 8. The .NET 5.0 release is now “feature complete”, meaning that very nearly all features are in their final form (with the exception of bug fixes still to come). Preview 8 is, appropriately, the last preview. We plan on releasing two go-live release candidates before the final .NET 5.0 release in November. This post describes a selection of features across the .NET 5.0 release.
