Could not find a base address that matches scheme net.tcp for the endpoint with binding NetTcpBinding. Registered base address schemes are [http].

 

Recently I have create WCF service and hosted in IIS 7.5 under was.

Then I investigate the reason and found the reason.In order to over come this issue we need to have both http,net.tcp protocols in hosted web application advanced settings under Behavior section.

.

No connection could be made because the target machine actively refused it error in WAS hosted WCF service

 

Recently I have created wcf service which is on NetTCPBinding and hosted in WAS.But when I try to create proxy using WCFtestClient its always failed prompting this error.

The reason for this is the host sent a reset signal, instead of an ack when the client tried to connect. It is therefore not a problem in the code. Either there is a firewall blocking the connection or the process that is hosting the service is not listening on that port.

• There fore we need to marks service port  as allowed port in the server firewall by defining new rule.
• Need to running NetTcpPort Sharing windows service and Net.Tcp  Distner adapter windows service.

After doing above two steps its works   

Doesn’t show windows authentication in IIS 7

Recently when I try to deploy my web application to newly setup windows server, in the IIS it doesn’t listed the windows authentication option  under authentication

In order to have listed windows authentication you need to install it by going to the Server Manager and checking Windows Authentication Check box

Server Manager—>web Service--->Add Role Service

Note : - In this machine already installed the Windows authentication .other wise check box will be enabled.

404.2 The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server

recently I got this error when I deploy my asp .net application to the IIS.Reason for is that by default iis 7 didn’t allow ISAPI and CGI.There fore you need to allow those properties manually by using actions pane

 

login failed for user ‘rob’ reason the account has expired

 

Promoting this error message my application has stopped working.The reason for that is expiration of the user which i have use to connect to sql server.later on i have investigate the user account in sqlserver and identified the root cause for that.

when i was creating the user i have checked the Enforce Password Expiration Check

Finally i uncheck the check and changed the password again.now its work fine

In C#, how to check if a TCP port is available?

When hosting wcf service which is use net tcp binding and without port sharing in a windows service , we should make sure the availability of our wcf port number. Other wise service doesn't start.

There fore as a best practice its is better to have code which will check the availability of the port when starting the service.This code should included to the service startup event. 

   1: protected override void OnStart(string[] args)

   2:        {

   3:            try

   4:            {

   5:                if (serviceHost != null)

   6:                {

   7:                    serviceHost.Close();

   8:                }

   9:  

  10:                PortChecker pc = new PortChecker();

  11:  

  12:                if (pc.IsPortAvailable())

  13:                {

  14:                    serviceHost = new ServiceHost(typeof(M3ISPlusService));

  15:                    serviceHost.Open();

  16:                }

  17:            }

ANd this is the port checker class

   1: public bool IsPortAvailable()

   2:         {

   3:             bool isAvailable = false;

   4:             TcpListener tcpListner = new TcpListener(GetServerIp(), GetPort());

   5:             Logger logger = Logger.GetLogger();

   6:  

   7:             try

   8:             {

   9:                 tcpListner.Start();

  10:                 isAvailable = true;

  11:             }

  12:             catch (Exception ex)

  13:             {

  14:                 logger.Log(ex.Message);

  15:             }

  16:  

  17:             finally

  18:             {

  19:                 try

  20:                 {

  21:                     tcpListner.Stop();

  22:                     tcpListner = null;

  23:                 }

  24:                 catch (Exception)

  25:                 {

  26:                     tcpListner = null;

  27:                 }

  28:             }

  29:  

  30:             return isAvailable;

  31:         }

To get port in code please refer my previous post :- Read End point address programmatically

Happy Coding :)

Programmatically reading endpoint address from web.config file?

 

There are some instances where we have to read wcf endpoint url from the code.As following you can accomplish that task.

once we add a service to the code it will get added to web.config under <system.serviceModel> section.

so we can access web config like this.

ServicesSection servicesSection = (ServicesSection)ConfigurationManager.GetSection(BASE_ADDRESS_PATH);

var item = servicesSection.Services[0].Host.BaseAddresses[0].BaseAddress;
Uri baseAddress = new Uri(item);
