Cache

Injects method cache code.

This is an add-in for Fody

Introduction to Fody

This project was forked by MethodCache original. And updated to support DotNet Core.

Milestone

• Support dotnet core
• Support instance of class cache
• Support static of method cache
• Support property of class cache
• Support complex parameters of method cache
• Support duration control

Your Code

[Cache(Duration = 3600)]
public int Add(int a, int b)
{
	return a + b;
}

What gets compiled

public int Add(int a, int b)
{
	string cacheKey = string.Format("Namespace.Class.Add_{0}_{1}", new object[] { a, b });

	if(Cache.Contains(cacheKey))
	{
		return Cache.Retrieve<int>(cacheKey);
	}
	
	int result = a + b;
	
	Cache.Store(cacheKey, result, new Dictionary<string, object>() { {"Duration", 3600}} );
	
	return result;
}

Usage

See also Fody usage.

NuGet installation

Install the Cache.Fody NuGet package and update the Fody NuGet package:

PM> Install-Package Cache.Fody
PM> Update-Package Fody

The Update-Package Fody is required since NuGet always defaults to the oldest, and most buggy, version of any dependency.

Add to FodyWeavers.xml

Add <Cache/> to FodyWeavers.xml

<?xml version="1.0" encoding="utf-8" ?>
<Weavers>
  <Cache/>
</Weavers>

Whats in the NuGet

In addition to the actual weaving assembly the NuGet package will also add a file CacheAttribute.cs to the target project.

[AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Module | AttributeTargets.Class | AttributeTargets.Method | AttributeTargets.Constructor,AllowMultiple = false)]
class CacheAttribute : Attribute
{
}
