Proxy: Implementation and Example

Implementing the Proxy design pattern

Let’s imagine that we have some back-end service that we can retrieve data from and submit new data to. However, retrieving the data happens to be a long and computationally expensive process. This is what we’ll simulate to demonstrate how the Proxy design pattern can be applied to solve such a problem.

Creating a new application

We’ll create a new .NET console application, and we will add the IDataService interface to it, which will look as follows:
