Azure function is not logging custom events, dependencies to app insights

We have a Azure Function V3 developed in C#. We tried to log some custom events, dependencies, etc to Azure Application Insights. We are not able to log in app insights using TelemetryClient. The code runs fine without any errors. Also, could see instrumentation key retrieved from config file. However Ilogger logs can be found in app insights traces table. Please find below code that we used,
public class CommunityCreate
{
private readonly TelemetryClient telemetryClient;
public CommunityCreate(TelemetryConfiguration telemetryConfiguration)
{
this.telemetryClient = new TelemetryClient(telemetryConfiguration);
}
[FunctionName("Function1")]
[return: ServiceBus("sample", Connection = "ServiceBusProducerConnection")]
public async Task<string> Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = "Account/{id:int?}")] HttpRequest req, string id, ILogger log)
{
//log.LogInformation("C# HTTP trigger function processed a request.");
DateTime start = DateTime.UtcNow;
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
var evt = new EventTelemetry("Function called");
evt.Context.User.Id = name;
this.telemetryClient.TrackEvent(evt);
// Generate a custom metric, in this case let's use ContentLength.
this.telemetryClient.GetMetric("contentLength").TrackValue(req.ContentLength);
// Log a custom dependency in the dependencies table.
var dependency = new DependencyTelemetry
{
Name = "GET api/planets/1/",
Target = "swapi.co",
Data = "https://swapi.co/api/planets/1/",
Timestamp = start,
Duration = DateTime.UtcNow - start,
Success = true
};
dependency.Context.User.Id = name;
this.telemetryClient.TrackDependency(dependency);
telemetryClient.TrackEvent("Ack123 Recieved");
telemetryClient.TrackMetric("Test Metric", DateTime.Now.Millisecond);
return name;
}
}

Please make sure you're using the correct packages as below:
Microsoft.Azure.WebJobs.Logging.ApplicationInsights, version 3.0.18
and
update the package Microsoft.NET.Sdk.Functions the latest version 3.0.9.
If you're running the project locally, please add the APPINSIGHTS_INSTRUMENTATIONKEY in local.settings.json, like below:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "xxxx",
"FUNCTIONS_WORKER_RUNTIME": "dotnet",
"APPINSIGHTS_INSTRUMENTATIONKEY": "xxx"
}
}
Or if you're running it on azure portal, please configure the Application insights with azure function.
Then I tested your code, the custom events or dependency are correctly logged into Application insights. Here is the screenshot:
If you still have the issue, please let me know(and please also provide more details).

How can we add existing links in Azure DevOps programmatically

I want to link the existing work items which are already created in a project under Azure DevOps by writing a code or program in C#, so is there any kind of API or SDK which can be used to link the work items programmatically?
The Workitems can be of any type i.e.
Bug
User Story
Issue
Task etc.
The linking between the Workitems can also be of any type i.e. Relational, Parent-Child, etc.
Recently I referred to this link for my problem.
The link contains issue very much related and similar to mine, however it is not working as expected when I tried it.

Given:
//int relatedId = ...
//int id = ...
//CancellationToken token = ...
//string organization = ...
//string projectName = ...
//WorkItemTrackingHttpClient azureClient = ...
Create a JsonPatchDocument as below:
JsonPatchDocument patchDoc = new JsonPatchDocument();
patchDoc.Add(
new JsonPatchOperation
{
From = null,
Operation = Operation.Add,
Path = "/relations/-",
Value = new {
rel = "System.LinkTypes.Related",
url = $"https://dev.azure.com/{organization}/{projectName}/_workitems/edit/{relatedId}",
attributes = new
{
comment = $"Created programmatically on {DateTime.Now}."
}
}
}
);
and call this async method of Azure DevOps SDK:
await azureClient.UpdateWorkItemAsync(patchDoc, id, false, true, true, WorkItemExpand.All, cancellationToken: token);
In the case above we created a related link using System.LinkTypes.Related referenceName.
For a full link types reference guide in Azure DevOps refer to this so's question or this microsoft's doc.

Graph API - adding Schema Extension using .Net Core 3.1

I need to add custom claims to my Azure B2C users, so I figured the way to do this is to add schema extensions to the User for my directory App with Graph API (beta).
I wrote a simple test for that:
SchemaExtension schemaExtension = new SchemaExtension
{
Id = schemaName,
Owner = _appClientId.ToString(),
Description = string.IsNullOrWhiteSpace(schemaDesc) ? string.Empty : schemaDesc.Trim(),
TargetTypes = new List<string>
{
"User"
},
Properties = new List<ExtensionSchemaProperty>
{
new ExtensionSchemaProperty
{
Name = "isGlobalAdmin",
Type = "Boolean"
},
new ExtensionSchemaProperty
{
Name = "isOrganizationAdmin",
Type = "Boolean"
}
}
};
SchemaExtension extension = await GraphClient.SchemaExtensions
.Request()
.AddAsync(schemaExtension);
First, it didn't work because of lack of permissions. So I created a new user in my directory and added Global Admin role to it. Then I set Treat application as a public client to true in the app authentication settings. That fixed permission problem.
But now I have this one:
Microsoft.Graph.ServiceException : Code: Service_InternalServerError
I tried changing params for the SchemaExtension but nothing helps.
How can I make this work?
API I use - Microsoft.Graph.Beta
UPDATE - Graph API init
private async Task<GraphServiceClient> InitGraphClientWithUserAndPassword()
{
try
{
IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
.Create(_appClientId.ToString())
.WithTenantId(_tenantId.ToString())
.Build();
UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication); // scopes
GraphServiceClient graphClient = new GraphServiceClient(authProvider);
SecureString securePass = new NetworkCredential("", _password).SecurePassword;
User me = await graphClient.Me.Request()
.WithUsernamePassword(_userEmail, securePass)
.GetAsync();
return graphClient;
}
catch (Exception ex)
{
const string ERR_MSG = "Could not create GraphAPI client";
_logger.LogError(ex, ERR_MSG);
throw new IlgGraphApiException(ERR_MSG, ex);
}
}

I have tested your code. It works fine for Azure AD but gets error Code: Service_InternalServerError\r\nMessage: Encountered an internal server error.\r\n\r\nInner error\r\n for Azure AD B2C.
I don't think Microsoft Graph API Create schemaExtension is supported for Azure AD B2C currently.
As this article says, Custom attributes in Azure AD B2C use Azure AD Graph API Directory Schema Extensions. Support for newer Microsoft Graph API for querying Azure AD B2C tenant is still under development.

Azure Storage Emulator - Configuring CORS dynamically throws Server Authentication error

I'm using Microsoft.WindowsAzure.Storage C# library in .Net Core 2.0.
Using this library I'm trying to configure CORS dynamically in Azure Storage Emulator but getting error:
"Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature".
public async void ConfigureCors() {
ServiceProperties serviceProperties = await this.blobClient.GetServicePropertiesAsync();
serviceProperties.Cors = new CorsProperties();
serviceProperties.Cors.CorsRules.Clear();
serviceProperties.Cors.CorsRules.Add(new CorsRule() {
AllowedHeaders = allowedCorsHeaders,
ExposedHeaders = allowedCorsExposedHeaders,
AllowedOrigins = allowedCorsOrigin,
AllowedMethods = allowedCorsMethods,
MaxAgeInSeconds = allowedCorsAgeInSeconds
});
await blobClient.SetServicePropertiesAsync(serviceProperties);
}
I'm able to generate SAS key for upload files on local server directly, but is not able to configure CORS dynamically so that I can access storage via C# code.
Strange thing to note is that the above code is working perfectly fine when using Azure Storage Cloud but local emulator is throwing this error.
Version info:
WindowsAzure.Storage version is 8.4.0
Windows Azure Storage Emulator version 5.2.0.0
Azure storage explorer version is 0.9.01
Credentials used for connection:
AccountName=devstoreaccount1;
AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuF‌​q2UVErCz4I6tq/K1SZFP‌​TOtr/KBHBeksoGMGw==;

According to your description, I have created a test demo on my side. It works well.
I guess the reason why you get the Server failed to authenticate the request error is the wrong azure storage package version and storage emulator version.
I suggest you could update the storage version to 8.4.0 and storage emulator version to 5.2 firstly and try again.
More details about my test demo, you could refer to below codes:
CloudStorageAccount storageAccount = CloudStorageAccount.Parse("UseDevelopmentStorage=true");
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
ServiceProperties serviceProperties = blobClient.GetServicePropertiesAsync().Result;
serviceProperties.Cors = new CorsProperties();
serviceProperties.Cors.CorsRules.Clear();
serviceProperties.Cors.CorsRules.Add(new CorsRule()
{
AllowedHeaders = new List<string>() { "*" },
ExposedHeaders = new List<string>() { "*" },
AllowedOrigins = new List<string>() { "*" },
AllowedMethods = CorsHttpMethods.Put | CorsHttpMethods.Get | CorsHttpMethods.Head | CorsHttpMethods.Post,
MaxAgeInSeconds = 1800
});
var re = blobClient.SetServicePropertiesAsync(serviceProperties);
Result:

Connect CouchDB with asp.net C# application

How to connect couchDB with ASP.NET C# application? If any one can you give a sample application.

I had the same need and after evaluating the options available, to meet the requirements of my application, I created any components that helped me a lot and maybe they can help you and also others. I make it clear that I have no intention of promoting myself here, just sharing something that may be useful.
The detailed explanation of how to configure and use it is on Github.

Example of use for retrieving documents with mango-querie:
IList<User> users;
var sts = new List<String> { "ACTIVE", "LOCKED" };
using (UserRepository db = new UserRepository())
{
var query = db.FindOf("list-status", new { id = "OwnerIdloop.user.7", statuses = sts });
users = db.List<User>(query);
}
Array.ForEach(users.ToArray(), Console.WriteLine);
Example of adding documents:
User user = createUser("email#email.com");
using (UserRepository db = new UserRepository())
{
var result = db.Insert<User>(user); // add document and return instance changed with operation revision id
Console.WriteLine(result.Revision);
}
Example of changing documents:
using (UserRepository db = new UserRepository())
{
// Load document data by ID
var user = db.Get<User>("email#email.com");
user.Name = user.Name + "::CHANGED";
var result = db.Update<User>(user); // update document and return instance changed with operation revision id
Console.WriteLine(result.Revision);
}
Example of deleting documents:
using (UserRepository db = new UserRepository())
{
// Load document data by ID
var user = db.Get<User>("email#email.com");
var result = db.Delete<User>(user); // delete document from database. Return true case sucess or false case not deleted
Console.WriteLine($"Sucesso: {result}");
}

After installing the NuGet, just create an instance of MyCouch.Client and pass it the URL of your database.
using (var client = new MyCouchClient("http://127.0.0.1:5984/test"))
{
//Consume here
}
The format is: {scheme}://[{username}:{password}]/{authority}/{localpath}. From v0.11.0, there's a specific MyCouchUriBuilder that you can use for building the Uri. It will automatically e.g. apply Uri.EscapeDataString to username and password when calling SetBasicCredentials.
var uriBuilder = new MyCouchUriBuilder("http://localhost:5984/")
.SetDbName(TestConstants.TestDbName)
.SetBasicCredentials("foob#r", "p#ssword");
return new MyCouchClient(uriBuilder.Build());
