Dependency injection in ASP.NET Core 2 throws exception

Question

I receive following exception when I try to use custom DbContext in Configure method in Startup.cs file. I use ASP.NET Core in version 2.0.0-previe

In ASP.NET Core 2.0 and newer you can simply inject the scoped service you need into the Configure constructor, like you tried to do initially:

public void Configure(
    IApplicationBuilder app,
    IHostingEnvironment env,
    ILoggerFactory loggerFactory,
    CommunicatorContext dbContext,
    ILdapService ldapService)
{
  // ...
}

This is a lot easier, thanks to the improvements in #1106.
