DbContextOptionsBuilder<TContext>.UseMemoryCache(IMemoryCache) Method

Definition

Namespace:

Microsoft.EntityFrameworkCore

Assembly:

Microsoft.EntityFrameworkCore.dll

Package:

Microsoft.EntityFrameworkCore v8.0.0

Sets the IMemoryCache to be used for query caching by this context.

public virtual Microsoft.EntityFrameworkCore.DbContextOptionsBuilder<TContext> UseMemoryCache (Microsoft.Extensions.Caching.Memory.IMemoryCache? memoryCache);

override this.UseMemoryCache : Microsoft.Extensions.Caching.Memory.IMemoryCache -> Microsoft.EntityFrameworkCore.DbContextOptionsBuilder<'Context (requires 'Context :> Microsoft.EntityFrameworkCore.DbContext)>

Public Overridable Function UseMemoryCache (memoryCache As IMemoryCache) As DbContextOptionsBuilder(Of TContext)

Parameters

memoryCache

IMemoryCache

The memory cache to be used.

Returns

DbContextOptionsBuilder<TContext>

The same builder instance so that multiple calls can be chained.

Remarks

Note that changing the memory cache can cause EF to build a new internal service provider, which may cause issues with performance. Generally it is expected that no more than one or two different instances will be used for a given application.

This method cannot be used if the application is setting the internal service provider through a call to UseInternalServiceProvider(IServiceProvider). In this case, the IMemoryCache should be configured directly in that service provider.

See Using DbContextOptions and Caching in .NET for more information.
