Highlights.NET 8 and EF8The highly requested feature Raw SQL queries for unmapped types is now included in the 30+ enhancements ready for EF8 preview 1. For example, for some arbitrary type not included in the EF model: public class PostSummary
{
public string BlogName { get; set; }
public string PostTitle { get; set; }
public DateTime PublishedOn { get; set; }
}A SQL query can be used to return instances of this type: var start = new DateTime(2022, 1, 1);
var end = new DateTime(2023, 1, 1);
var summaries =
await context.Database.SqlQuery<PostSummary>(
@$"SELECT b.Name AS BlogName, p.Title AS PostTitle, p.PublishedOn
FROM Posts AS p
INNER JOIN Blogs AS b ON p.BlogId = b.Id
WHERE p.PublishedOn >= {start} AND p.PublishedOn < {end}")

HighlightsEF8 Preview 2 is on NuGet now!Preview 2 contains support for JSON column mapping on SQLite and official* support for the Hierarchy IDs are used to map tree structures. For example, the diagram below shows the hierarchy ID mappings for a paternal family tree of halflings:
We can then use these mappings to, for example, find the common ancestor of Bilbo and Frodo: async Task<Halfling?> FindCommonAncestor(Halfling first, Halfling second)
=> await context.Halflings
.Where(
ancestor => first.PathFromPatriarch.IsDescendantOf(ancestor.PathFromPatriarch)
&& second.PathFromPatriarch.IsDescendantOf(ancestor.PathFromPatriarch))
.OrderByDescending(ancestor => ancestor.PathFromPatriarch.GetLevel())
.FirstOrDefaultAsync();Which translates to: SELECT TOP(1) [h].[Id], [h].[Name], [h].[PathFromPatriarch], [h].[YearOfBirth]
FROM [Halflings] AS [h]
WHERE @__first_PathFromPatriarch_0.IsDescendantOf([h].[PathFromPatriarch]) = CAST(1 AS bit)
AND @__second_PathFromPatriarch_1.IsDescendantOf([h].[PathFromPatriarch]) = CAST(1 AS bit)
ORDER BY [h].[PathFromPatriarch].GetLevel() DESCAnd the answer is, of course, Balbo. See aka.ms/ef8-new for more fun with halflings and other documentation for Preview 1 and Preview 2.

This included using “hierarchyid” on SQL Server/Azure SQL and “ltree” on PostgresSQL, with demos using a family tree structure.

HighlightsMerged this week: massively improved data type detection when scaffolding a DbContext and entity types from a SQLite database. SQLite databases have very limited (and strange) support for the type of data stored in a column. In addition to using column metadata, EF Core now samples data in the column to determine which .NET type to use. This means columns with date/time types, GUIDs, booleans, etc. are correctly detected and entity types are scaffolded with appropriate property types. Community Standup: Azure SQL Database and SQL Server 2022 - What’s new for developersIn the latest .NET Data Community Standup, Silvano Coriani joins the .NET Data Access team to discuss some of the new capabilities introduced on both SQL Server and our Azure services that have an impact on app development.

HighlightsEF Core 8 Preview 4 is on NuGet now!
Here's an example of a query that can now be translated using the new support for primitive collections. This query will tell us how common it is for a dog walk to coincide with a visit to the nearest pub: 
Which translates to the following on SQL Server: 
See the What's New documentation and blog post for more examples. Community Standup: Collections of primitive values in EF CoreIn the latest .NET Data Community Standup, the .NET Data Access team dive into new support for collections of primitive values, just released in EF Core 8 Preview 4. Collections of a primitive type can now be used as properties of an entity type and will be mapped to a JSON column in the relational database. In addition, parameters of primitive values can be passed to the database. In either case, the native JSON processing capabilities of the database are then used to exact and manipulate the primitive values, just as if they were in a table. This opens up powerful query possibilities, as well as optimizations to common problems such as translating queries that use Contains. You can watch all .NET Data Community Standups on YouTube.

HighlightsEF Core 8 Preview 5 is on NuGet now! Preview 5 contains the following new features:
Community Standup: Synchronizing data between the cloud and the clientIn the latest .NET Data Community Standup, we talke to Erik Sink about a solution for keeping a synchronized copy of the DB (using SQLite) on the client, rather than asking data for the cloud every time. This is helpful for mobile scenarios where the connectivity may be poor, but the "rep and sync" approach can reduce the time the user spends waiting on the network. Local writes are fast, sync happens in the background. We explore how this is done efficiently, how to deal with conflict resolution, and other data sync-related concerns. Community Standup: New CLI edition of EF Core Power ToolsIn a recent .NET Data Community Standup, ErikEJ demonstrates the new CLI edition of EF Core Power Tools and shows how he used a number of community NuGet packages to improve the user experience when creating a CLI tool.

Highlights
Boolean columns with non-false default values are now handled correctly, including when scaffolded from an existing database. For example, consider this table:
CREATE TABLE [Members] ( [Id] int NOT NULL IDENTITY, [Name] nvarchar(max) NULL, [IsActive] bit NOT NULL DEFAULT CAST(1 AS bit), CONSTRAINT [PK_Member] PRIMARY KEY ([Id]))EF8 now parses literal values in column default constraints, allowing
HasDefaultValueto be scaffolded instead ofHasDefaultValyeSql. For example,CAST(1 AS bit)is parsed astrue:EF checks the value of a property to determine whether or not to let the database generate a value. Starting with EF8, this check can be customized. This means that EF8 will send
falseto the database when needed, since database default is known to betrue.In addition:
