Asp.net-mvc – WCF Service with asp.net mvc application

asp.net-mvcwcf

I have started using asp.net MVC and as traditional way I want to keep my data access layer in WCF service. How can I achieve that using asp.net MVC ?

Scenario

I started a test application in asp.net MVC which Displays, Inserts and Edit data.
I successfully created that by adding 'ADO.Net Entity Data Model'.

So now if I wanted to move this dataaccess layer in WCF service, i.e. a WCF service with methods like GetData(), UpdateData(), CreateNewData(), how can i achieve that?

Short Answer:

You just need to move your dataaccess layer into a WCF service, expose it and then call it from your MVC application.

Long Answer:

1) I recommend going through Scott Guthrie's Nerd Dinner walkthrough to get a really good understanding of MVC basics.

2) The following blog goes through the process of writing a Layered ASP.NET MVC Applicaiton with a WCF Service (Parts III & IV specifically concentrate on WCF & MVC interaction):

Part I (General Concepts)
Part II (Building a Repository)
Part III (Building The Service)
Part IV (Using The Service)

I haven't read the linked arrticles in detail (just skimmed them) but they seem to give a decent overview of the process.

Asp.net-mvc – ASP.NET MVC & Web Services

It sounds like you should split out your model into its own assembly and reference it from your MVC-application and WCF-application.

YourApp.Data -- Shared model and data access maybe
YourApp.Web -- If you want to share more across your web-apps
YourApp.Web.Mvc
YourApp.Web.WebService

If you want to do WebServices MVC-style maybe you should use MVC to build your own REST-application.

Asp.net-mvc – How to cache data in a MVC application

Here's a nice and simple cache helper class/service I use:

using System.Runtime.Caching;  

public class InMemoryCache: ICacheService
{
    public T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class
    {
        T item = MemoryCache.Default.Get(cacheKey) as T;
        if (item == null)
        {
            item = getItemCallback();
            MemoryCache.Default.Add(cacheKey, item, DateTime.Now.AddMinutes(10));
        }
        return item;
    }
}

interface ICacheService
{
    T GetOrSet<T>(string cacheKey, Func<T> getItemCallback) where T : class;
}

Usage:

cacheProvider.GetOrSet("cache key", (delegate method if cache is empty));

Cache provider will check if there's anything by the name of "cache id" in the cache, and if there's not, it will call a delegate method to fetch data and store it in cache.

Example:

var products=cacheService.GetOrSet("catalog.products", ()=>productRepository.GetAll())
