ZeroAlloc.Cache

Source-generated zero-allocation caching proxy from an annotated interface.

Add [Cache] to an interface and a Roslyn source generator emits a proxy class that transparently intercepts every method call, returning a cached result on hit with no heap allocation on the cache-hit path. Backed by IMemoryCache by default, with optional HybridCache (L1 + L2) opt-in per method. AOT-safe.

NuGet


Quick start

dotnet add package ZeroAlloc.Cache
[Cache(TtlMs = 60_000)]
public interface IProductRepository
{
    ValueTask<Product?> GetByIdAsync(int id, CancellationToken ct);

    [Cache(TtlMs = 300_000, MaxEntries = 1_000)]
    ValueTask<IReadOnlyList<Product>> SearchAsync(string query, CancellationToken ct);
}

// Register — one line wires everything
builder.Services.AddIProductRepositoryCache<ProductRepositoryImpl>();

Inject IProductRepository anywhere — caching is transparent to the caller.

public class ProductsController(IProductRepository repo)
{
    public async Task<Product?> Get(int id, CancellationToken ct)
        => await repo.GetByIdAsync(id, ct); // cache hit = zero allocation
}

Features

Feature Notes
Zero allocation on cache hit Key is built at compile time; no boxing, no string interpolation at runtime
IMemoryCache (default) In-process L1 cache; no extra dependencies
HybridCache (opt-in) L1 + L2 distributed cache via Microsoft.Extensions.Caching.Hybrid
Method-level override Any [Cache] on a method shadows the interface-level config for that method
MaxEntries Isolates the method in its own MemoryCache instance with a SizeLimit
Compile-time key Cache key expression is emitted by the generator — zero key-building overhead on hit
AOT / trimmer safe Generated proxy is concrete; no reflection at runtime
DI integration Generated Add{IService}Cache<TImpl>() extension registers everything

Cache behavior

Scenario Behavior
Miss Inner implementation is called; result is stored in cache with the configured TTL; result is returned
Hit Cached value is returned directly; inner implementation is never invoked; no heap allocation

Diagnostics

ID Severity Description
ZC0001 Warning Sliding = true combined with UseHybridCache = true — sliding TTL is silently ignored by the distributed (L2) tier
ZC0002 Warning A cache key parameter is a reference type (excluding string) — ToString() may not produce a stable unique key
