Creating a custom WCF REST service for SharePoint 2013 without a Visual Studio template

• Create a new SharePoint 2013 Empty Project as a Farm Solution

• Add a WCF Service Application project to your solution

• Add the ISAPI mapped folder to your SharePoint project

• Drag the Service1.svc and Service1.svc.cs files from the WCF project to the SharePoint project under the ISAPI mapped folder

• Drag the IService1.cs file from the WCF project to the SharePoint project

• Add the WCF references to your SharePoint project

1. System.Runtime.Serialization
2. System.ServiceModel
3. System.ServiceModel.Web

• Change the namespace from MyService to your assembly's namespace (e.g., MyRestService) in Service1.svc.cs and IService1.cs

• Remove a WCF Service Application project to your solution

• Build your project

• Using the Visual Studio Command Prompt, go to the project output folder of the SharePoint project

sn -T MyRestService.dll

• In Service1.svc, change the Service attribute on the ServiceHost directive to be in the following format:

<%@ ServiceHost Language="C#" Debug="true" Service="{NameSpace}.{ServiceName}, {AssemblyName}, Version=1.0.0.0, Culture=Neutral, PublicKeyToken={PublicKeyToken}" CodeBehind="Service1.svc.cs" %>

Replace the tokens here, represented by {Token} with the appropriate values for your project. e.g.,

<%@ ServiceHost Language="C#" Debug="true" Service="MyRestService.Service1, MyRestService, Version=1.0.0.0, Culture=Neutral, PublicKeyToken=099213f2a077836f" CodeBehind="Service1.svc.cs" %>



• Deploy your solution
• Verify the service loads
• Note: see below for troubleshooting a common error.
• Add a HelloWorld operation to your contract, IService1.cs that is set up for REST.

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "HelloWorld")]
string HelloWorld();

• Implement the operation in Service1.svc.cs

public string HelloWorld()
{
    return "Hello World";

}

• Update web.config with the appropriate info for your service

 <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MyServiceServiceBehavior">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true">
          </serviceMetadata>
          <serviceDebug includeExceptionDetailInFaults="true">
          </serviceDebug>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="jsonBehaviour">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service name="MyRestService.Service1" behaviorConfiguration="MyServiceServiceBehavior">
        <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="MyRestService.IService1">
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
      </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true">
    </serviceHostingEnvironment>
  </system.serviceModel>

Test your HelloWorld operation and you should see the following:

http://win-0n4jtsv8137/_vti_bin/Service1.svc/HelloWorld

If you want to use multiple services for same solution you can add Service Details in web config file like below

<services> <service name="LeaveManagementSystem.LMSService" behaviorConfiguration="LMSServiceServiceBehavior"> <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="LeaveManagementSystem.LMSIService"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"> </endpoint> </service> <service name="MyRestService.Service1" behaviorConfiguration="LMSServiceServiceBehavior"> <endpoint address="" binding="webHttpBinding" behaviorConfiguration="jsonBehaviour" contract="MyRestService.IService1"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"> </endpoint> </service> </services>

• If you want to pass values through WCF Service

you can write Below code in IService.cs

[OperationContract]
[WebGet(ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "Types")]

List<Types> Types();


[DataContract]
    public class Types
    {
        [DataMember]
        public int ID { get; set; }

        [DataMember]
        public string Title { get; set; }

    }

you can write Below code in Service.svc.cs

List<Types> IService.Types()
        {
            var resultTypes = new List<Types>();
            DataTable dtType = objLMS.GetType();

            resultLeaveTypes = (from DataRow row in dtType.Rows
                                select new Types
                                {
                                    ID = Convert.ToInt32(row["ID"]),
                                    Title = Convert.ToString(row["Title"])

                                }).ToList();

            return resultTypes;

        }

• If you want to get values From WCF Service

you can write Below code in IService.cs

[OperationContract]

[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "ApplyforLeave?Leavetype={Leavetype}&FromDate={FromDate}&ToDate={ToDate}&Duration={Duration}&PhoneNumber={PhoneNumber}&Reason={Reason}")]

void ApplyforLeave(Int32 Leavetype, DateTime FromDate, DateTime ToDate, Int32 Duration, String PhoneNumber, String Reason);

you can write Below code in Service.svc.cs

public void ApplyforLeave(int Leavetype, DateTime FromDate, DateTime ToDate, int Duration, string PhoneNumber, string Reason) {

return "Your value is " + Convert.ToString(Leavetype) + " FromDate is " + Convert.ToString(FromDate) + " ToDate is " + Convert.ToString(ToDate) + " Duration is " + Convert.ToString(Duration) + " PhoneNumber is " + PhoneNumber + " Reason is " + Reason;

}
