ISqlExpressionFactory Interface

Definition

Namespace:

Microsoft.EntityFrameworkCore.Query

Assembly:

Microsoft.EntityFrameworkCore.Relational.dll

Package:

Microsoft.EntityFrameworkCore.Relational v8.0.0

A factory for creating SqlExpression instances.

Remarks

The service lifetime is Scoped. This means that each DbContext instance will use its own instance of this service. The implementation may depend on other services registered with any lifetime. The implementation does not need to be thread-safe.
