How to get the application's ProductName in Silverlight - silverlight

Question

Is it possible to programmatically get the ProductName of a Silverlight application? I'm looking for the Silverlight equivalent of this WinForms/WPF instruction:
string productName = System.Windows.Forms.Application.ProductName;
Thank you

You can use the following method, but only if you can guarantee that you call it from the "entry" assembly.
public static void GetProductAndVersionEasy(out string productName, out Version productVersion)
{
var callingAssembly = Assembly.GetCallingAssembly();
// Get the product name from the AssemblyProductAttribute.
// Usually defined in AssemblyInfo.cs as: [assembly: AssemblyProduct("Hello World Product")]
var assemblyProductAttribute = ((AssemblyProductAttribute[])callingAssembly.GetCustomAttributes(typeof(AssemblyProductAttribute),false)).Single();
productName = assemblyProductAttribute.Product;
// Get the product version from the assembly by using its AssemblyName.
productVersion = new AssemblyName(callingAssembly.FullName).Version;
}
(You can replace GetCallingAssembly with GetExecutingAssembly if the method is in your entry assembly).
I also figured out how to hack this information from the .xap file. I load the main assembly's bytes into memory, then read the product and version info from the last few bytes. I had to write this because I needed a method I could reuse in a base library which can be called from anywhere (ie. not the executing or calling assembly).
public static void GetProductAndVersionHack(
out string productName,
out Version productVersion)
{
// Get the name of the entry assembly
var deployment = System.Windows.Deployment.Current;
var entryPointAssembly = deployment.EntryPointAssembly + ".dll";
// Get the assembly stream from the xap file
StreamResourceInfo streamResourceInfo = Application.GetResourceStream(
new Uri(
entryPointAssembly,
UriKind.Relative));
Stream stream = streamResourceInfo.Stream;
// The VERSION_INFO struct as at the end of the file. Just read the last 1000 bytes or so from the stream
// (Keep in mind that there are a lot of zeroes padded at the end of the stream. You should probably
// search for the real stream.Length after trimming them off)
stream.Position = stream.Length - 1000;
StreamReader streamReader = new StreamReader(stream, Encoding.Unicode);
string text = streamReader.ReadToEnd();
// Split the string on the NULL character
string[] strings = text.Split(
new[] { '\0' },
System.StringSplitOptions.RemoveEmptyEntries);
// Get the Product Name (starts with unicode character \u0001)
int ixProductName = strings.FindIndexOf(line => line.EndsWith("\u0001ProductName"));
productName = ixProductName >= 0 ? strings[ixProductName + 1] : null;
// Get the Product Version
int ixProductVersion = strings.FindIndexOf(line => line.EndsWith("\u0001ProductVersion"));
productVersion = ixProductVersion >= 0 ? Version.Parse(strings[ixProductVersion + 1]) : null;
}
public static int FindIndexOf<T>(
this IEnumerable<T> source,
Func<T, bool> match)
{
int i = -1;
foreach (var item in source)
{
++i;
if (match(item)) return i;
}
return -1;
}

Not sure what device your deving for, but for WP7 silverlight, In the Properties folder contained a file called WMAppManifest.xml, and under Deployment>App their is a field called Title, you can pull the XML out of there?
I hope that helps.

The AssemblyName class provides parsing of the Assembly FullName property.
Try this
string productName = (new System.Reflection.AssemblyName(this.GetType().Assembly.FullName)).Name;
