Storing of the C4H authentication credential (Username and Password) can be as simple or as complex as you prefer.

An example of a simple implementation can be compiling the DLL with the credentials hard coded inside in the following manner:

FIGURE 6 Store the C4H Authentication Credential

Steps to implement above example:

1. Open Visual Studio.
2. Create a new C# Class Library project.

FIGURE 7 Create a New C# Class Library Project

1. Name the project and set the location.
2. Right-click on References and select Add Reference.
   1. Navigate to copy of Plexis.ClaimEditingSoftware and select.

FIGURE 8 Select Plexis.ClaimEditingSoftware

1. Right-click on the project and select Add > Class.

FIGURE 9 Select Add > Class

FIGURE 10 Select Add > Class

1. Provide a name for the class.

FIGURE 11 Provide a Name

1. In the newly created class (see Figure 7 for reference).
2. Provide using statements for the following assemblies:
   • 
     
     1. System.Net
     2. System.Security
     3. Plexis.ClaimEditingSoftware
3. Implement ICesCredential
   • 
     
     1. Add “: ICesCredential” to the public class declaration
        1. public class CesCredential : ICesCredential
           1. Ensure the class has a public access modifier.
     2. Right-click on ICesCredential and select “Implement Interface”
        1. This creates the function stub for implementation.
        2. You may follow the example in Figure 7 to create implementation.
4. Right-click project and select Build.
5. The compiled DLL for the project will be available in the Project Bin folder.
6. This is the assembly that needs to be referenced in the Castle ExternalCredential component Type. The name of the class that implements ICesCredential is also referenced in the Component Type.
