c# - Security Transparent alternative for RuntimeHelpers.PrepareDelegate -

i need pre-jit emitted delegates ahead of time , tried using runtimehelpers.preparedelegate this, method marked securitycritical attribute. assembly marked allowpartiallytrustedcallers attribute , can hence not phone call security critical code.

why preparedelegate , preparemethod security critical , alternatives alternatives have in pre-jitting delegates?

as referenced in msdn article ca2140: transparent code must not reference security critical items:

how prepare violations

to prepare violation of rule, 1 of following:

mark code element uses security critical code securitycriticalattribute attribute

- or -

remove securitycriticalattribute attribute code elements marked security critical , instead mark them securitysafecriticalattribute or securitytransparentattribute attribute.

you have mark method pre-jiting [securitysafecriticalattribute]. here in action:

using system; using system.runtime.compilerservices; using system.reflection; using system.security; [assembly: allowpartiallytrustedcallers] namespace consoleapplication1 { class programme { static void main(string[] args) { prejit(); } [securitysafecritical] static void prejit() { runtimehelpers.preparemethod( system.reflection.emit.dynamicmethod.getcurrentmethod() .methodhandle); } } }
