c# - Where should I put logic for run once after web api server is bootstrapped? -

for example have server:

using (httpselfhostserver server = new httpselfhostserver(config)) {     server.openasync().wait();     console.writeline("press enter quit.");     console.readline(); } 

and controller:

public class productscontroller : apicontroller {     // here route("....")     public product getproductbyid(int id)     {         var product = productsprovider.firstordefault((p) => p.id == id);         if (product == null)         {             throw new httpresponseexception(httpstatuscode.notfound);         }         return product;     } } 

after server unexpectedly terminated want process requests cached in database. how can call controller/action or simulate request after server bootstrapped?
