How to create event with videoconference in Google Meet in C# using Google Calendar API?

Well.. I'm trying this code to create an Event
CalendarService service;
GoogleCredential credential;
try
{
string[] scopes = new string[] { CalendarService.Scope.Calendar };
using (var stream = new FileStream(#"C:\Prueba\meet.json", FileMode.Open, FileAccess.Read))
{
credential = GoogleCredential.FromStream(stream)
.CreateScoped(scopes);
}
service = new CalendarService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential
});
Event calendarEvent = new Event();
DateTime start = DateTime.Now;
calendarEvent.Kind = "";
calendarEvent.Summary = "prueba";
calendarEvent.Status = "confirmed";
calendarEvent.Visibility = "public";
calendarEvent.Description = "prueba";
calendarEvent.Creator = new Event.CreatorData
{
Email = "email#example.com", //email#example.com
Self = true
};
calendarEvent.Organizer = new Event.OrganizerData
{
Email = "email#example.com",
Self = true
};
calendarEvent.Start = new EventDateTime
{
DateTime = start,
TimeZone = "America/Mexico_City"
};
calendarEvent.End = new EventDateTime
{
DateTime = start.AddHours(1),
TimeZone = "America/Mexico_City"
};
calendarEvent.Recurrence = new String[] { "RRULE:FREQ=DAILY;COUNT=1" };
calendarEvent.Sequence = 0;
calendarEvent.HangoutLink = "";
calendarEvent.ConferenceData = new ConferenceData
{
CreateRequest = new CreateConferenceRequest
{
RequestId = "1234abcdef",
ConferenceSolutionKey = new ConferenceSolutionKey
{
Type = "hangoutsMeet"
},
Status = new ConferenceRequestStatus
{
StatusCode = "success"
}
},
EntryPoints = new List<EntryPoint>
{
new EntryPoint
{
EntryPointType = "video",
Uri = "",
Label = ""
}
},
ConferenceSolution = new ConferenceSolution
{
Key = new ConferenceSolutionKey
{
Type = "hangoutsMeet"
},
Name = "Google Meet",
IconUri = ""
},
ConferenceId = ""
};
//calendarEvent.EventType = "default";
EventsResource.InsertRequest request = service.Events.Insert(calendarEvent, "email#example.com");
request.ConferenceDataVersion = 0;
Event createEvent = request.Execute();
string url = createEvent.HangoutLink;
}
catch (Exception ex)
{
}
The source code is here
When I execute the line 116: Event createEvent = request.Execute();
I get this error: Google.Apis.Requests.RequestError Invalid conference type value. [400] Errors [Message[Invalid conference type value.] Location[ - ] Reason[invalid] Domain[global]
I don't know what means this error o with line I wrong
Could anyone help me with an example to create an event using classes C# from Google API Calendar?

As described in the C# library documentation for createRequest:
Either conferenceSolution and at least one entryPoint, or createRequest is required.
This means that you should use only CreateConferenceRequest as this conference is brand new (if it already existed then you would be wanting to use ConferenceSolution along with EntryPoints ). Therefore, simply remove ConferenceSolution and EntryPoints to leave just CreateConferenceRequest which as specified in the documentation is used for generating a new conference and attach it to the event.

How to create k8s deployment using kubernetes-client in c#?

I'm getting Microsoft.Rest.HttpOperationException: 'Operation returned an invalid status code 'BadRequest'' on this line.
var result = client.CreateNamespacedDeployment(deployment, namespace);
Kubernetes-client has a small number of good resources and most of them is written in other language such as java and python. So i'm referring to these documentations.
this is my implementation so far.
V1Deployment deployment = new V1Deployment()
{
ApiVersion = "extensions/v1beta1",
Kind = "Deployment",
Metadata = new V1ObjectMeta()
{
Name = "...",
NamespaceProperty = env,
Labels = new Dictionary<string, string>()
{
{ "app", "..." }
}
},
Spec = new V1DeploymentSpec
{
Replicas = 1,
Selector = new V1LabelSelector()
{
MatchLabels = new Dictionary<string, string>
{
{ "app", "..." }
}
},
Template = new V1PodTemplateSpec()
{
Metadata = new V1ObjectMeta()
{
CreationTimestamp = null,
Labels = new Dictionary<string, string>
{
{ "app", "..." }
}
},
Spec = new V1PodSpec
{
Containers = new List<V1Container>()
{
new V1Container()
{
Name = "...",
Image = "...",
ImagePullPolicy = "Always",
Ports = new List<V1ContainerPort> { new V1ContainerPort(80) }
}
}
}
}
},
Status = new V1DeploymentStatus()
{
Replicas = 1
}
};
var result = client.CreateNamespacedDeployment(deployment, namespace);
I want to know the proper way on how to create kubernetes deployment using kubernetes-client, and also i want to know the cause of this issue.

For the full clarity and future visitors, it's worth to mention, what is exactly behind this bad request error (code: 400) returned from API server, when using your code sample:
"the API version in the data (extensions/v1beta1) does not match the expected API version (apps/v1)"
Solution:
ApiVersion = "extensions/v1beta1" -> ApiVersion = "apps/v1"
Full code sample:
private static void Main(string[] args)
{
var k8SClientConfig = new KubernetesClientConfiguration { Host = "http://127.0.0.1:8080" };
IKubernetes client = new Kubernetes(k8SClientConfig);
ListDeployments(client);
V1Deployment deployment = new V1Deployment()
{
ApiVersion = "apps/v1",
Kind = "Deployment",
Metadata = new V1ObjectMeta()
{
Name = "nepomucen",
NamespaceProperty = null,
Labels = new Dictionary<string, string>()
{
{ "app", "nepomucen" }
}
},
Spec = new V1DeploymentSpec
{
Replicas = 1,
Selector = new V1LabelSelector()
{
MatchLabels = new Dictionary<string, string>
{
{ "app", "nepomucen" }
}
},
Template = new V1PodTemplateSpec()
{
Metadata = new V1ObjectMeta()
{
CreationTimestamp = null,
Labels = new Dictionary<string, string>
{
{ "app", "nepomucen" }
}
},
Spec = new V1PodSpec
{
Containers = new List<V1Container>()
{
new V1Container()
{
Name = "nginx",
Image = "nginx:1.7.9",
ImagePullPolicy = "Always",
Ports = new List<V1ContainerPort> { new V1ContainerPort(80) }
}
}
}
}
},
Status = new V1DeploymentStatus()
{
Replicas = 1
}
};

Closing this issue (Resolved)
Reference: https://github.com/Azure/autorest/issues/931
Cause of issue: incorrect version of Kubernetes ApiVersion.
Solution: get and replace ApiVersion from kubernetes api.
Can also handle the exception using:
try
{
var result = client.CreateNamespacedDeployment(deployment, namespace);
}
catch (Microsoft.Rest.HttpOperationException httpOperationException)
{
var phase = httpOperationException.Response.ReasonPhrase;
var content = httpOperationException.Response.Content;
}

bad request - request too long

I use IdentityServer3. My startup class is bellow.
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/identity", idsrvApp =>
{
var corsPolicyService = new DefaultCorsPolicyService()
{
AllowAll = true
};
var idServerServiceFactory = new IdentityServerServiceFactory()
.UseInMemoryClients(Clients.Get())
.UseInMemoryScopes(Scopes.Get());
//.UseInMemoryUsers(Users.Get());
idServerServiceFactory.CorsPolicyService = new Registration<IdentityServer3.Core.Services.ICorsPolicyService>(corsPolicyService);
idServerServiceFactory.ViewService = new Registration<IViewService, CustomViewService>();
idServerServiceFactory.UserService = new Registration<IUserService>(resolver => new CustomUserService());
var options = new IdentityServerOptions
{
EnableWelcomePage = false,
Factory = idServerServiceFactory,
SiteName = "Justice Identity Server",
IssuerUri = IdentityConstants.ecabinetIssuerUri,
PublicOrigin = IdentityConstants.ecabinetSTSOrigin,
AuthenticationOptions = new IdentityServer3.Core.Configuration.AuthenticationOptions() {
CookieOptions = {
AllowRememberMe=false,
Prefix="IC"
},
EnablePostSignOutAutoRedirect = true,
},
SigningCertificate = LoadSertificate(),
CspOptions = new CspOptions()
{
Enabled = true,
ScriptSrc = "'unsafe-inline'",
ConnectSrc = "*",
FrameSrc = "*"
},
};
idsrvApp.UseIdentityServer(options);
});
}
X509Certificate2 LoadSertificate()
{
return new X509Certificate2(string.Format(#"{0}\certificates\cert.pfx", AppDomain.CurrentDomain.BaseDirectory), "123", X509KeyStorageFlags.MachineKeySet);
}
}
After sometimes I have got "bad request-request too long" ,when I clear cookie it works. I have seen in console a lot of nonce cookies.
Anyone could help me?
thanks you

This is a known issue.

Royal Mail Shipping API C#

I'm trying to integrate the Royal Mail SOAP API into my .NET Code. I have followed the advice here Consume WCF Royal Mail API in c# Console Application and here C# WCF Namespaces Move To Header & Use NS Prefix.
I have created a custom IClientMessageFormatter to be able to attach the namespaces to the beginning of the soap envelope, but I still can't seem to get this to work. I keep receiving the following error. Could not establish trust relationship for the SSL/TLS secure channel with authority 'api.royalmail.com', and the inner exception is: The remote certificate is invalid according to the validation procedure.
I am using Visual Studio 13 and .Net version 3.5, I've tried numerous other versions but with no further progress. When I debug I can see that the normal message been passed into the RoyalMailMessage but when it runs OnWriteStartEnvelope I can't see any changes to the _message object. I've created a trace to see what soap request is been sent.
I have sent my XML request to Royal Mail support who validate that the reason it is failing is due to the namespaces not been declared in the envelope and the missing prefixes.

The error you are getting is basically because of the certificate.
Having said that, I think you should use the v2 of the API as although it is still awful, there are examples out there and you don't need to use a cert.
Rick Strahl has successfully changed the namespaces in the v2 version, see here https://weblog.west-wind.com/posts/2016/Apr/02/Custom-Message-Formatting-in-WCF-to-add-all-Namespaces-to-the-SOAP-Envelope .

There is one new Royal Mail Shipping API 2 available , after I've lost many hours try development the integration with Royal Mail I finally found a way. I'm sharing my project in the git.
