Problem with self-extracting archive in WPF C# with the DotNetZip library

[ilsanto2]

I tried the following example code, but it doesn't work in WPF C#

using Ionic.Zip;

string DirectoryPath = folder;
using (ZipFile zip = new ZipFile())
{
zip.AddDirectory(DirectoryPath, System.IO.Path.GetFileName(DirectoryPath));
zip.Comment = "This will be embedded into a self-extracting WinForms-based exe";
var options = new SelfExtractorOptions
{
Flavor = SelfExtractorFlavor.WinFormsApplication,
DefaultExtractDirectory = "%USERPROFILE%\\ExtractHere",
PostExtractCommandLine = ExeToRunAfterExtract,
SfxExeWindowTitle = "My Custom Window Title",
RemoveUnpackedFilesAfterExecute = true
};
zip.SaveSelfExtractor("archive.exe", options);
}

names are not found in wpf c# project

SelfExtractorOptions
SelfExtractorFlavor
ExeToRunAfterExtract
SaveSelfExtractor

How can I solve it?
