Create new or WCF application according to your requirement. Then go to your code behind page and write the following code for example using Gmail.

public void SendEmail()




SmtpClient clientSMTP = new SmtpClient(“”, 587);


clientSMTP.EnableSsl = true;

clientSMTP.DeliveryMethod = SmtpDeliveryMethod.Network;

clientSMTP.UseDefaultCredentials = false;

clientSMTP.Credentials = new NetworkCredential(“”,”password”);

using (MailMessage message = new MailMessage())


message.From = new MailAddress(“yourgmailid”);

message.Subject = “Subject”;

message.IsBodyHtml = true;

How to increase the Windows Phone App limited memory?

Windows Phone App is limited to use 150 MB at maximum per app. But sometimes it is required to more than this limit at least to run in high spec devices. To solve this problem, you can define on your App to ensure you have high availability of application memory.

To increase the size of memory usage we add the following node to the Manifest file of Windows Phone App:




&lt;FunctionalCapability Name=”ID_FUNCCAP_EXTEND_MEM”/&gt;



There is another Functional Capability which will ensure the large memory is available before running the application and opt out the Low memory phones from running the app. If this is your requirement you can use:




&lt;Requirements Name=”ID_REQ_MEMORY_300″/&gt;



If you use the above capability, the App won’t appear in Windows Phone Store for lower memory phones and it can’t be installed in low end devices.

Based on your requirement, you can increase the size boundary from 150 MB to 300 MB or for some devices up to 1GB of application memory usage.

How to find if the user has tapped on the Screen in Windows Phone 8 App?

//     A wired headset for output only; the input is received from the default microphone.

WiredHeadsetSpeakerOnly = 5,

BluetoothWithNoiseAndEchoCancellation = 6,


Note: You need to add the ID_CAP_VOIP capability in your WMAppManifest file.

Windows Phone performance killers and tips

Don’t use too many Converters and Bindings they are Performance Killers

Converters are one of the most significant killers of performance (second perhaps to binding itself) in a XAML application.


Load only the content needed.

The smaller the content, the faster loading occurs.

Use DXT to compress textures.

Compressed the content is smaller, sometimes dramatically smaller. This reduces loading time.

Allocate memory for Reusable Objects.

Allocate a set of reusable objects and reinitialize them as needed. Reusable objects never need to be freed, and reduce the number of additional allocations.

Manually call GC.Collect()

Manually call the garbage collector at the time of loading screen.

Measuring Performance

There several tools available for analyzing the .NET garbage collection heap. One tool available from Microsoft is the CLR Profiler. The tool is free and it is available for download at

Steps to run the CLR profiler

Download the CLR Profiler, and then extract the files.

Navigate to CLRProfiler\Binaries\x86 (or x64), and then run CLRProfiler.exe.

Click Start Application, and then select your application.

It will generates a graph that displays information about all objects in the garbage collection heap, and a references related to these structures.

Keep overall memory use under 90 MB.
