DbConfiguration.SetModelCacheKey Method

Definition

Namespace:

System.Data.Entity

Assembly:

EntityFramework.dll

Call this method from the constructor of a class derived from DbConfiguration to set a Func<T,TResult> as the model cache key factory which allows the key used to cache the model behind a DbContext to be changed.

protected internal void SetModelCacheKey (Func<System.Data.Entity.DbContext,System.Data.Entity.Infrastructure.IDbModelCacheKey> keyFactory);

member this.SetModelCacheKey : Func<System.Data.Entity.DbContext, System.Data.Entity.Infrastructure.IDbModelCacheKey> -> unit

Protected Friend Sub SetModelCacheKey (keyFactory As Func(Of DbContext, IDbModelCacheKey))

Parameters

keyFactory

Func<DbContext,IDbModelCacheKey>

The key factory.

Remarks

This method is provided as a convenient and discoverable way to add configuration to the Entity Framework. Internally it works in the same way as using AddDependencyResolver to add an appropriate resolver for Func<T,TResult>. This means that, if desired, the same functionality can be achieved using a custom resolver or a resolver backed by an Inversion-of-Control container.
