Basic authentication requires a secure connection to the server. in TFS

I was try to connect my TFS server using my credentials . But i am getting error 'Basic authentication requires a secure connection to the server.'
string username = "adminuser";
string pwd = "mypassword";
string domain = "http://localhost:8080/tfs/defaultcollection";
NetworkCredential networkCredential = new NetworkCredential(username, pwd);
BasicAuthCredential basicAuthCredential = new BasicAuthCredential(networkCredential);
TfsClientCredentials tfsClientCredentials = new TfsClientCredentials(basicAuthCredential)
{
AllowInteractive = false
};
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(new Uri(domain), tfsClientCredentials);
tfs.EnsureAuthenticated();
My tfs didn't have the https. Any alternative to fix it But browser level it is working fine

The BasicAuthCredential requires https://, I believe, and I wasn't able to access my TFS with https://. So I found another way to get from NetworkCredential to VssCredentials.
string username = "adminuser";
string pwd = "mypassword";
string domain = "http://localhost:8080/tfs/defaultcollection";
NetworkCredential networkCredential = new NetworkCredential(username, pwd);
//BasicAuthCredential basicAuthCredential = new BasicAuthCredential(networkCredential);
Microsoft.VisualStudio.Services.Common.WindowsCredential winCred = new Microsoft.VisualStudio.Services.Common.WindowsCredential(networkCredential);
VssCredentials vssCred = new VssClientCredentials(winCred);
TfsTeamProjectCollection tfs = new TfsTeamProjectCollection(new Uri(domain), vssCred);
tfs.EnsureAuthenticated();

Try using the following code:
String collectionUri = "http://localhost:8080/tfs/defaultcollection";
VssCredentials creds = new VssClientCredentials();
creds.Storage = new VssClientCredentialStorage();
VssConnection connection = new VssConnection(new Uri(collectionUri), creds);

getting error like "Connection did not succeed. Try again later". using Microsoft.Exchange with delegates and Impersonation

below Useexchangeservice method used for connect mail server and getting mail from server but its showing error like "Connection did not succeed. Try again later".
static void UseExchangeService()
{
string userEmailAddress = "xyz2#domain.com";
string userPassword = "testnew#123";
ExchangeService service = new
ExchangeService(ExchangeVersion.Exchange2010_SP2);
#region Authentication
service.UseDefaultCredentials = true;
service.TraceEnabled = true;
service.TraceFlags = TraceFlags.All;
var folder = new FolderId(WellKnownFolderName.Calendar, new Mailbox(userEmailAddress));
#endregion
#region Endpoint management
service.AutodiscoverUrl(userEmailAddress,
RedirectionUrlValidationCallback);
#endregion
EmailMessage email = new EmailMessage(service);
email.ToRecipients.Add("Lalit.Sharma2#securemeters.com");
email.Subject = "HelloWorld";
email.Body = new MessageBody("Sent by using the EWS Managed API");
email.Save(new FolderId(WellKnownFolderName.Drafts, "Lalit.Sharma2#securemeters.com"));
email.Send();
}

Getting error while Authenticating online TFS from WCF service

I am trying to connect online TFS using WCF service but it is throwing me exception "TF30063: You are not authorized to access https://abdul-r.visualstudio.com/DefaultCollection/TestTFS.".
Below is my sample code
NetworkCredential netCred = new NetworkCredential(
"*MyEmail*",
"*MyPassword*");
BasicAuthCredential basicCred = new BasicAuthCredential(netCred);
TfsClientCredentials credential = new TfsClientCredentials(basicCred);
credential.AllowInteractive = false;
string TFSServerPath = "https://abdul-r.visualstudio.com/DefaultCollection/TestTFS";
using (TfsTeamProjectCollection tfs1 = new TfsTeamProjectCollection(new Uri(TFSServerPath), credential))
{
tfs1.EnsureAuthenticated();
}
Any help would be appreciated.

Error authorized to tfs programmatically

I have local tfs 2012. On Visual studio 2012 , use c# , I write program which programmatically connect to tfs server. But I have error:
{"TF30063: You are not authorized to access http://server:8080/tfs."} System.Exception {Microsoft.TeamFoundation.TeamFoundationServerUnauthorizedException}
My code:
Uri collectionUri = new Uri("http://server:8080/tfs");
NetworkCredential netCred = new NetworkCredential("login","password");
BasicAuthCredential basicCred = new BasicAuthCredential(netCred);
TfsClientCredentials tfsCred = new TfsClientCredentials(basicCred);
tfsCred.AllowInteractive = false;
TfsTeamProjectCollection teamProjectCollection = new TfsTeamProjectCollection(collectionUri, netCred);
teamProjectCollection.EnsureAuthenticated();//throw error here
Can you help me fix this error?
P.S. I try do connect this way, but I have same error:
var projectCollection = new TfsTeamProjectCollection(
new Uri("http://myserver:8080/tfs/DefaultCollection"),
new NetworkCredential("youruser", "yourpassword"));
projectCollection.Connect(ConnectOptions.IncludeServices);
And this way:
Uri collectionUri = new Uri("http://server:8080/tfs/DefaultCollection");
NetworkCredential netCred = new NetworkCredential("login","password","Server.local");
BasicAuthCredential basicCred = new BasicAuthCredential(netCred);
TfsClientCredentials tfsCred = new TfsClientCredentials(basicCred);
tfsCred.AllowInteractive = false;
TfsTeamProjectCollection teamProjectCollection = new TfsTeamProjectCollection(collectionUri, netCred);
teamProjectCollection.EnsureAuthenticated();

Hope it helps you.
var tfsCon = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://server:8080/tfs"));
tfsCon.Authenticate();
var workItems = new WorkItemStore(tfsCon);
var projectsList = (from Project p in workItems.Projects select p.Name).ToList();
or
Uri TfsURL = new Uri(""http://server:8080/tfs"");
NetworkCredential credential = new NetworkCredential(Username, Password, Domain);
TfsTeamProjectCollection collection = new TfsTeamProjectCollection(TfsURL, credential);
collection.EnsureAuthenticated();
If fails here you need to configure in App.config to set the default proxy:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true"></defaultProxy>
</system.net>
</configuration>

(407) Proxy Authentication Required ( The ISA Server requires authorization to fulfill the request. Access to the Web Proxy filter is denied

I know that this error is very common, but I tried to apply the solutions to this problem and could not solve it.
Thats my code:
var endpoint = new EndpointAddress(new Uri("http://www3prz.bancobonsucesso.com.br/Servicos/app.svc"), EndpointIdentity.CreateDnsIdentity("bancobonsucesso.com.br"));
var binding = new WSHttpBinding();
binding.UseDefaultWebProxy = true;
binding.Security.Mode = SecurityMode.Message;
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
binding.Security.Message.EstablishSecurityContext = true;
binding.Security.Message.NegotiateServiceCredential = true;
var customBinding = new CustomBinding(binding);
SymmetricSecurityBindingElement security = customBinding.Elements.Find<SymmetricSecurityBindingElement>();
security.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
security.LocalClientSettings.DetectReplays = false;
SecureConversationSecurityTokenParameters secureTokenParams = (SecureConversationSecurityTokenParameters)security.ProtectionTokenParameters;
SecurityBindingElement bootstrap = secureTokenParams.BootstrapSecurityBindingElement;
bootstrap.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
bootstrap.LocalClientSettings.DetectReplays = false;
ws = new ServicoClient(customBinding, endpoint);
ws.ClientCredentials.ServiceCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None;
ws.ClientCredentials.UserName.UserName = "test";
ws.ClientCredentials.UserName.Password = "test";
var return = ws.EmitirBoleto("test");

IN the WCF Binding use useDefaultWebProxy:
<bindings>
<basicHttpBinding>
<binding name="bindingName" useDefaultWebProxy="true">
WebProxy wproxy = new WebProxy("new proxy",true);
wproxy.Credentials = new NetworkCredential("user", "pass");
WebRequest.DefaultWebProxy = wproxy;

This error may arise problem with proxy settings.
Please check Proxy setting with your web browser. Just changed connection settings Option -> settings -> connection settings to Auto detect proxy settings
Good luck ...
