+# This workflow uses actions that are not certified by GitHub.
+# They are provided by a third-party and are governed by
+# separate terms of service, privacy policy, and support
+# documentation.
+
+# This workflow will build, test, sign and package a WPF or Windows Forms desktop application
+# built on .NET Core.
+# To learn how to migrate your existing application to .NET Core,
+# refer to https://docs.microsoft.com/en-us/dotnet/desktop-wpf/migration/convert-project-from-net-framework
+#
+# To configure this workflow:
+#
+# 1. Configure environment variables
+# GitHub sets default environment variables for every workflow run.
+# Replace the variables relative to your project in the "env" section below.
+#
+# 2. Signing
+# Generate a signing certificate in the Windows Application
+# Packaging Project or add an existing signing certificate to the project.
+# Next, use PowerShell to encode the .pfx file using Base64 encoding
+# by running the following Powershell script to generate the output string:
+#
+# $pfx_cert = Get-Content '.\SigningCertificate.pfx' -Encoding Byte
+# [System.Convert]::ToBase64String($pfx_cert) | Out-File 'SigningCertificate_Encoded.txt'
+#
+# Open the output file, SigningCertificate_Encoded.txt, and copy the
+# string inside. Then, add the string to the repo as a GitHub secret
+# and name it "Base64_Encoded_Pfx."
+# For more information on how to configure your signing certificate for
+# this workflow, refer to https://github.com/microsoft/github-actions-for-desktop-apps#signing
+#
+# Finally, add the signing certificate password to the repo as a secret and name it "Pfx_Key".
+# See "Build the Windows Application Packaging project" below to see how the secret is used.
+#
