i've project using aspnet mvc5 webapi2, owin , simpleinjector ioc container.
i've read if you're using owin should httpconfiguration, you'll create 1 rather using globalconfiguration.
like in startup class, configuration method:
var config = new httpconfiguration(); config.dependencyresolver = new simpleinjectorwebapidependencyresolver(container); but receive error need parameterless contructor, , if use:
globalconfiguration.configuration.dependencyresolver = new simpleinjectorwebapidependencyresolver(container); combined (in simpleinjectorinitializer):
container.registerwebapicontrollers(globalconfiguration.configuration, appdomain.currentdomain.getassemblies()); it works, read on internet:
a common error in owin integration use of globalconfiguration.configuration. in owin create configuration scratch. should not reference globalconfiguration.configuration anywhere when using owin integration.
am doing ok owin , frameworks , technologies being used?
i've tried follow implementation of simpleinjector webapi (there they're using mvc changed little). mvc 5 template (asp.net identity 2.0) combined simple injector
this snippet of startup class now:
public partial class startup { public void configuration(iappbuilder app) { var container = simpleinjectorinitializer.initialize(app); globalconfiguration.configuration.dependencyresolver = new simpleinjectorwebapidependencyresolver(container); configureauth(app, container); } public void configureauth(iappbuilder app, container container) { // added ioc usage: see https://simpleinjector.codeplex.com/discussions/564822 app.use(async (context, next) => { using (container.beginexecutioncontextscope()) { await next(); } }); app.createperowincontext(() => container.getinstance<applicationusermanager>()); // enable application use cookie store information signed in user // , use cookie temporarily store information user logging in third party login provider app.usecookieauthentication(new cookieauthenticationoptions()); app.useexternalsignincookie(defaultauthenticationtypes.externalcookie); // configure application oauth based flow publicclientid = "self"; oauthoptions = new oauthauthorizationserveroptions { tokenendpointpath = new pathstring("/token"), provider = new applicationoauthprovider(publicclientid), authorizeendpointpath = new pathstring("/api/account/externallogin"), accesstokenexpiretimespan = timespan.fromdays(14), // in production mode set allowinsecurehttp = false allowinsecurehttp = true }; // enable application use bearer tokens authenticate users app.useoauthbearertokens(oauthoptions); } simpleinjectorinitializer class

if take @ same page got quote from, you'll see have register web api configuration owin's iappbuilder follows:
app.usewebapi(config);
