Solution
This is known issue in latest couple of .Net SAML SP versions.
SecurityException error when running saml2.exe happens if .NET runtime 2.0 is installed on the host windows server
Workaround is to create saml2.exe.config file in same folder with saml2.exe to override what runtime version saml2.exe is to use.
saml2.exe.config contents :
<?xml version="1.0"?>
<configuration>
<startup>
<supportedRuntime version="v4.0"/>
</startup>
</configuration>
