In many cases, using a caching mechanism can drastically improve performances. Processed results of methods can be stored in memory or in files so they are ready to be returned immediately when we call the methods again.
In some .NET applications, we can use the MemoryCache class from System.Runtime.Caching to store data in memory. However, using such library in a basic way may induce some problems such as:
- Adding caching in each method which needs it may result in less readable and polluted code.
- The repetitive use of such code may induce errors (especially copy-pasted code).
- Depending on the nature of projects (mobile apps, websites, web services, desktop apps), we may need a different caching approach.
In order to avoid all these problems, I have written a generic caching aspect using Autofac and Castle DynamicProxy. Continue reading “Caching method results easily with AOP”
