Not sure if this is related/helpful but FWIW I recently had to get a codesign certificate for my windows store app (for local testing/installs). The following command line scripts work for me in case they help anyone else.

Part 1: Generate the Cert

(Run these from Visual Studio 201x Command Prompt)

# 1) Generate .PVK and .CER
MakeCert /n "CN=YourMSPartnerPublisherIDString" /r /h 0 /eku "1.3.6.1.5.5.7.3.3,1.3.6.1.4.1.311.10.3.13" /sv MyAppName.pvk MyAppName.cer

# 2) Generate .PFX
Pvk2Pfx /pvk  MyAppName.pvk /pi "password" /spc MyAppName.cer /pfx MyAppName.pfx /po "password"

Part 2: Create the APPX from EXE and sign the APPX w/the Cert

(Run these from Command Line as Administrator)

# 3) Generate APPX from EXE
# (Assumes you have your App EXE and valid AppManifest.xml in C:\MyAppFolder\AppxPackage folder)
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64\makeappx.exe" pack /p "C:\MyAppFolder\MyAppName.appx" /d "C:\MyAppFolder\AppxPackage"

# 4) Sign APPX with Cert
"C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x64\signtool.exe" sign /fd sha256 /a /f "C:\MyAppFolder\CertMyAppName.pfx" /p password "C:\MyAppFolder\MyAppName.appx"
