Is there a way to get the value that is stored in the AssemblyVersion
attribute that's in AssemblyInfo.cs?

Yes, you can get a reference to the currently executing assembly and
then get it's custom attributes (filtering by type: AssemblyVersionAttribute)
like this,

using System.Reflection;
// . . .
Assembly assy = Assembly.GetExecutingAssembly( );
AssemblyVersionAttribute[] versionAttrs = (AssemblyVersionAttribute[ ])
assy.GetCustomAttributes( typeof( AssemblyVersionAttribute), false);
if ( versionAttrs != null && 0 < versionAttrs.Length ) {
Console.WriteLine( "Assembly version is {0}.", versionAttrs[ i].Version);
}

GetCustomAttributes( ) works for any Attribute but it returns an array of
plain object references, so don't forget to typecast it to the appropriate
Type of Attribute. If you pass the Type as the argument then you can be
guaranteed that the typecast is valid.

Of course I left off the qualifying phrase: "in .Net Compact Framework".
Grrr. GetCustomAttribute is not in the Compact Framework. Might just go
back to what I had originally, hard-coded value in C#.

Except pseudo custom attributes such as AssemblyVersionAttribute. To
get the version you use assy.GetName().Version.

Please reply only to the newsgroup.

Or a slightly simpler way:

string version = Assembly.GetExecutingAssembly().GetName().Version.ToString();
