If you want to hard code sensitive information about service address on your code use some obfuscation tool like SmartAssembly and use string encryption feature. If you want to have this information on app.config file or registry you can use custom encryption\decryption to protect them.

Update:

For an example of code refer to: Encrypting & Decrypting a String in C#
