When I try to call
var ninjectKernel = new StandardKernel();
I get the below error. I can successfully use ninject with constructor injection. I only get this error when I try to grab a service by hand.

I recently went through Confluent Kafka library in C# .net 4.7.2 framework version. But, many times I faced Local Value serialization error. Is this error is a generic one? or this error tells anything specifically? I'm not sure when will this error raises?
var rs = (RecordSchema)RecordSchema.Parse(#"{
""namespace"": ""Confluent.Kafka.Examples.AvroSpecific"",
""type"": ""record"",
""name"": ""ProduceConsumeUser2"",
""fields"": [
{""name"": ""name"", ""type"": ""string""},
{""name"": ""favorite_number"", ""type"": [""int"", ""null""]},
{""name"": ""favorite_color"", ""type"": [""string"", ""null""]}
]}");
using (var schemaRegistry = new CachedSchemaRegistryClient(schemaRegistryConfig)){
using (var genericProducer = new ProducerBuilder<string, GenericRecord>(producerConfig)
.SetValueSerializer(new AvroSerializer<GenericRecord>(schemaRegistry).AsSyncOverAsync())
.Build())
{
var genericRecord = new GenericRecord(rs);
genericRecord.Add("name", "my name 2");
genericRecord.Add("favorite_number", 44);
genericRecord.Add("favorite_color", null);
var message = new Message<string, GenericRecord>
{
Key = contentEventName,
Value = genericRecord
};
Task.Run(() => genericProducer.ProduceAsync(contentEventName, message)).ConfigureAwait(false).GetAwaiter().GetResult();
}}

I cannot be for certain. But I got to this page because I had the same exception details /issue...
For me, solving the issue was making sure I had the correct credentials for the Schema Registry. DOH! Hope this helps for at least someone else!
In my C# test using the Confulent.Kafka and Confluent.SchemaRegistry the (username:password) are that exact syntax with the (:) colon in one string
string credentials ="MyUserName:mypassword";
var schemaRegistryConfig = new SchemaRegistryConfig()
{
Url = config.GetValue<string>("ConfluentCloud:SchemaRegistry:Url", string.Empty),
BasicAuthUserInfo = config.GetValue<string>("ConfluentCloud:SchemaRegistry:Credentials", string.Empty),
};
// no serializer required for string key
using (var schemaRegistry = new CachedSchemaRegistryClient(schemaRegistryConfig))
... etc. etc.
I am trying to upgrade my web api to use OData V4 query syntax. After upgrading the dlls am able to issue $filter and $select queries for my web api.
But When I issue a request like https://localhost:65000/api/Entitlement?$apply=groupby((Grade)), getting below exception (am using NHibernate ORM)

I am using Umbraco 7.5.7 for my application When ever I click on the content item in CMS it shows me this error, I have provided the code below, can some help me on this.
HttpContext.Current.Session and UmbracoContext.Current.HttpContext.Session is always null in Umbraco CMS while accessing content and throwing
Received an error from the server
-"value cannot be null. Parameter Name: httpSessionState" error on the cms UI
IManageState.cs

I have also tried the below code, I replaced this line
get { return _session ?? new HttpSessionStateWrapper(HttpContext.Current.Session); }
with
get { return _session != null ? _session : HttpContext.Current.Session != null ? new HttpSessionStateWrapper(HttpContext.Current.Session): UmbracoContext.Current.HttpContext.Session ; }

Here is what I have
I have a view component as
public class TestViewComponent : ViewComponent
{
public async Task<IViewComponentResult> InvokeAsync(int param1, int param2)
{
return Content(param1.ToString() + param2);
}
}
And a controller as
public class HomeController : Controller
{
private Dictionary<string, object> _dict = new Dictionary<string, object>();
public IActionResult Index()
{
_dict = new Dictionary<string, object>() { ["param1"] = 100, ["param2"] = 200 };
return ViewComponent("Test", _dict)
}
public IActionResult Index1()
{
var obj = new { param1 = 100, param2 = 200 };
var objString = JsonConvert.SerializeObject(obj);
_dict = JsonConvert.DeserializeObject<Dictionary<string, object>>(objString);
return ViewComponent("Test", _dict);
}
}
When I call the first Index action everything is good. It works as expected but when I call the Index1 action I get an error with the following stack trace
System.InvalidCastException: Unable to cast object of type 'System.Int64' to type 'System.Int32'.

It seems there is some issue after the Deserialization. The exception is thrown even before the InvokeAsync method of the view component is called.
I have been stuck on this for a while. Any help will be really appreciated.
Thanks.
The error message is pretty much telling what's happening here. The actual objects in the deserialized dictionary are Int64s, which the arguments expected by the ViewComponent are Int32 (also called int in C#).
Maybe I'm not understanding what a VirtualFileResult is, but I'm not sure why it's throwing a FileNotFoundException when the file exists. Here's the code:
if (System.IO.File.Exists(fileName))
{
FileInfo info = new FileInfo(fileName);
return File(fileName, FileUtility.GetContentType(fileName), info.Name);
}
(Edit: FileUtility.GetContentType (correctly) returns the Mime type of the file, which in my case is "application/pdf".)
Here's the exception I get: (I removed the file path)
System.IO.FileNotFoundException: Could not find file: [file path removed]
File name: '[file path removed]'

It's seemingly bugging out even though an explicit check was done for whether the file exists or not. I can also manually confirm the file exists.
Maybe I'm not understanding what a VirtualFileResult is (File method returns this). On the documentation here it doesn't really describe what it is.
I'm using ASP.NET 5 RC1.
The method you're looking for is PhysicalFile():
return PhysicalFile(fileName, FileUtility.GetContentType(fileName), info.Name);
Beware, don't use a caller-supplied path with this.
The VirtualFileResult class needs the virtual path to the file in its constructor.
This means you need to provide the path relative to the wwwroot folder because it use HostingEnvironment's WebRootFileProvider.
private IFileProvider GetFileProvider(IServiceProvider requestServices)
{
if (FileProvider != null)
{
return FileProvider;
}
var hostingEnvironment = requestServices.GetService<IHostingEnvironment>();
FileProvider = hostingEnvironment.WebRootFileProvider;
return FileProvider;
}
}
Check the code on github
No luck with File("index.html") or File("~/index.html"), Virtualfileresult throws NotFound.
My solution was to use Microsoft.AspNetCore.Mvc.ControllerBase
method File(Stream fileStream...) :
public virtual FileStreamResult File(Stream fileStream,
string contentType, string fileDownloadName);
Index controller sample:
using System.IO;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
public class IndexController : Controller
{
ILoggerFactory Logger;
public IndexController(ILoggerFactory loggerFactory)
{
Logger = loggerFactory;
}
static string sep = Path.DirectorySeparatorChar.ToString();
[HttpGet("/index")]
[HttpGet("/")]
public IActionResult Index()
{
var log = Logger.CreateLogger("trace");
var path = $"{Startup.RootPath}{sep}index.html";
log.LogWarning(path);
Stream fileStream = new System.IO.FileStream(path, FileMode.Open);
return File(fileStream, "text/html");
}
}
// AspnetCore version 1.1.1 :
// <TargetFramework>netcoreapp1.1</TargetFramework>
// <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="1.1.1" />
Your VirtualFileResult must be a relative path from the application's wwwroot.
return File("~/foo.js","text/javascript")
is going to point to wwwroot/foo.js
