how can utilize topshelf.ninject , incorporate owinninjectdependencyresolver (from ninject.web.webapi.owinhost)?

i can work need instantiate ninject kernel twice (once topshelf , 1 time httpconfiguration.dependencyresolver. not seem right way utilize ninject.

any help or illustration code related specific design helpful.

so had same problem , managed solve it.

the key to:

not utilize [assembly: owinstartup(...)] attribute bootstrap owin. inject ikernel using ninject service class beingness used configure topshelf. use start(startoptions options, action<owin.iappbuilder> startup) method of microsoft.owin.hosting.webapp class start self-hosted web-app. pass in injected kernel owin bootstrap routine via startup action. use passed-in reference kernel in phone call appbuilder.useninjectmiddleware(() => kernel); in owin startup routine, rather appbuilder.useninjectmiddleware(createkernel);. profit.

the finish solution follows:

create console application solution called backgroundprocessor. add packages listed in packages.config listing below solution using nuget. add app.config solution using listing below. add each of code files provided below solution; have provided total listings because of lines of code quite sensitive using statements because of heavy utilize of extension methods libraries utilized solution. compile , run project. test solution hitting url http://localhost:9000/test on local machine.
