asp.net core mvc - Dependencies in MVC 6 application of multilayered solution -

-

i developing solution includes data layer, business layer , ui layer (mvc 6 application).

mvc application works interfaces of business layer. doesn't know services (implementation of business layer) , data layer. has reference project contains business layer interfaces.

i have issue connected dependencies. according opinion, must add dependencies (including repositories , services) startup.cs file, mvc 6 application mustn't have references repositories or services.

how can add dependencies without adding references?

the mvc6 application must reference service , repository implementations, either directly or indirectly. thing should not construct instances of these implementations controller components.

so in other words, okay in startup.cs:

public void configureservices(iservicecollection services) {   services.addinstance<iserviceorrepo, serviceorrepoimpl>(); }

it not okay in controller:

private readonly iserviceorrepo _serviceorrepo;  public mycontroller() {   this._serviceorrepo = new serviceorrepoimpl(); }

but either way, @ runtime, controller must able resolve actual serviceorrepoimpl implementation instance 1 of referenced assemblies (via ioc container of course). means assembly or project contains implementation must referenced mvc project either directly or indirectly.

i trying debug c# code wrote consume web service. i'm hitting error when receiving response because content type of response doesn't match binding. exception snippet: an exception of type 'system.servicemodel.protocolexception' occurred in mscorlib.dll not handled in user code additional information: content type text/xml of response message not match content type of binding (application/soap+xml; charset=utf-8) the web service external can't change on end. know there lot of troubleshooting steps can take besides (and have tried many, it's not simple changing binding), there way view response message, or more info response, before hit exception? have custom message inspector written afterreceivereply method in it, exception occurs before method hit.

python - Terminate a gnome-terminal opened with subprocess -

using subprocess , command ' gnome-terminal -e bash ' can open gnome-terminal desired (and have stick around). done either p=subprocess.popen(['gnome-terminal', '-e', 'bash']) or p=subprocess.popen(['gnome-terminal -e bash'], shell=true) but cannot close terminal using p.terminate() or p.kill() . understand, little trickier when using shell=true did not expect run problems otherwise. to terminate terminal , children (in same process group): #!/usr/bin/env python import os import signal import subprocess p = subprocess.popen(['gnome-terminal', '--disable-factory', '-e', 'bash'], preexec_fn=os.setpgrp) # here... os.killpg(p.pid, signal.sigint) --disable-factory used avoid re-using active terminal can kill newly created terminal via subprocess handle os.setpgrp puts gnome-terminal in own process group os.killpg() used send signal group
