I can't run execute the method neither from console nor directly from my code, here's the important part of logs

 

LCPDFR.log:

[ERROR - 12:35:13] [Plugin.TestPlugin] System.MissingMethodException: Method not found: 'Void LCPD_First_Response.LCPDFR.API.Functions.StartCallout(System.String)'.
   at API_Example.TestPlugin.Process()
   at ay.b()
[ERROR - 12:35:13] [ExceptionHandler]  API_Example.TestPlugin.Process() L_ffffffff 
 ay.b() L_00a0 
Error hash: 4B730627DA46BEDC75E6101A0431339BD749D283

My VS links the StartCallout() properly but every in-game usage ends in the same way - an exception.

Have you ensured the assembly in the IV folder and the assembly you have referenced in your VS project are exactly the same?

Thank to your tip I managed to resolve the issue. My *.dll had an older version of LCPD First Response.dll as a reference, after recompilation with the newer one it works alright. Thanks LMS! 

Great to hear, no problem!
