Implementing a custom FormsAuthenticationProvider using Owin, Katana, and Nancy -

i working on implementing custom formsauthenticationprovider , i'm getting middleware conversion error.

no conversion available between system.func`2[system.collections.generic.idictionary`2 [system.string,system.object],system.threading.tasks.task] , microsoft.owin.owinmiddleware parameter name: signature 

my stack includes

• owin
• katana
• nancy

my specific question advice on example on how implement custom formsauthenticationprovider? unless can spot problem.

my implementation looks like:

startup.cs

app.useformsauthentication(new formsauthenticationoptions             {                 loginpath = "/login",                 logoutpath = "/logout",                 cookiehttponly = true,                 authenticationtype = constants.chainlinkauthtype,                 cookiename = "chainlink.id",                 expiretimespan = timespan.fromdays(30),                 provider = kernel.get<iformsauthenticationprovider>()             }); 

if remove app.useformsauthentication(...) application runs without error.
