I am choosing Empty template while creating a new asp.net core web application (.net core 3) as a option.
When I run project, I face with this error
System.TypeInitializationException: 'The type initializer for 'Microsoft.Extensions.Logging.EventSource.LoggingEventSource' threw an exception.'

What is this and how can I resolve it.
Thanks.
The problem was solved for me when I run the application on IIS instead of IIS Express.

My program.cs file in .NET Core 3.1 is like this I am creating web API in .net core but I am getting this error when hosted on server in IIS. API is working fine when hosted locally.
public class Program
{
public static void Main(string[] args)
{
var logger = NLogBuilder.ConfigureNLog(String.Concat(Directory.GetCurrentDirectory(), "/nlog.config")).GetLogger();
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
}).ConfigureLogging(logging =>
{
logging.ClearProviders();
logging.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace);
})
.UseNLog();
}

What is wrong here?
I am experiencing the same error, and I was trying to see what might cause it.
I came across this link with the same issue
and the thing that jumped out at me was the "non-graceful shutdown". To test, I recycled the application website on IIS, which did not trigger the error. I then tried turning off the app pool via IIS, and DID trigger the exception.
This leads me to believe it has something to do with a task running inside the application that is cut short when the non-graceful shutdown occurs.
In my case, I have a HostedService running in the background of my application, do you have something similar in yours?
I created an apk file and installed into my device. Afterwards, I try running my emulator on visual studio but it does not work anymore. It kept showing me errors. Does anyone know how to solve this issue?

I'm trying to Use this Blog for WCF RIA Applcation . So I Create a Silverlight Nevigation Applciation which gave me 2 projects abs & abs.Web
More I create 3 project in solution :
abs.Data (c#), DbContext Implemeantion of Repository Interfaces +Factory to provide What user want.
abs.Data.Contarct (c#) Interfaces for Operations Repository
abs.Data.Model (c#) - Contains POCO - EF 6
Now I created A wcf Service in abs.Web project which have constructor injection of a Repository to get my job done in operation contracts.
So I tried using Unity here under the guidence with below blog
http://jamesheppinstall.wordpress.com/2012/06/20/windows-communication-foundation-resolving-wcf-service-dependencies-with-unity/
Now I'm getting

My all classes are same as like Blog.
WCF Ria has its own factory.
Simply put
public class MyDomainServiceFactory : IDomainServiceFactory
{
#region IDomainServiceFactory Members
public DomainService CreateDomainService(Type domainServiceType, DomainServiceContext context)
{
try
{
if (!typeof (DomainService).IsAssignableFrom(domainServiceType))
{
throw new ArgumentException(String.Format("Cannot create an instance of {0} since it does not inherit from DomainService", domainServiceType), "domainServiceType");
}
if (IoC.IsRegistered(domainServiceType))
{
var dmnService = (DomainService) IoC.Resolve(domainServiceType);
dmnService.Initialize(context);
return dmnService;
}
else
{
//if the IoC container doesn't know the service, simply try to call its default constructor
//could throw proper exception as well
var dmnService = (DomainService) Activator.CreateInstance(domainServiceType);
dmnService.Initialize(context);
return dmnService;
}
}
catch (Exception ex)
{
ExceptionHandler.HandleException(ex);
return null;
}
}
public void ReleaseDomainService(DomainService domainService)
{
domainService.Dispose();
}
#endregion
}
and somewhere on your bootstrapping code add
DomainService.Factory = new MyDomainServiceFactory();
of course, the word IoC in the factory identify the unityContainer (is actually a static façade against it)
I just started a new Silverlight project with Visual Studio Express 2012 for Web.
I created a Silverlight-enabled WCF service to access a SQL Server database, with EF 5.
The problem I'm having is that the service doesn't seem to be able to return any entity retrieved from the database. A new entity or any old object is returned just fine, but when I try to return an entity from the context I get the following exception:
{System.ServiceModel.CommunicationException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.

The service method code couldn't be simpler:
[OperationContract]
public Contact GetContact(int aID)
{
Contact res = null;
using (var db = new OFBEntities())
{
try
{
res = db.Contacts.Find(aID);
}
catch (Exception ex)
{
res = null;
}
return res;
}
}
As I mentioned, if I return a newly created object (return new Contact(){ name="test contact};), or return a type that is not in context (say an integer for example), everything works fine.
Is this a limitation of the express version, or am I forgetting some settings? In the past I have created some Silverlight apps that consumed data services with VS 2010, Silverlight 4, and I don't remember having to set anything special, but maybe I just forgot that I did?
Any help is appreciated!
EDIT:
Could it have anything to do with DbContext and the way it is serialized? I've never used DbContext before, I always used the default ObjectContext in EF 4...
EDIT2: SOLUTION
It's been a while, but I had other things to work :o)
In case anybody is in the same boat, the problem was in the serialization by the service. DbContext by default creates proxies, which don't agree with serialization. I am not sure why yet - indeed, I need to educate myself about those proxies - but disabling them solves my serialization issue.
Thanks for the comment Pawel, I mistakenly thought my serialization was going OK, rechecking the server-side error put me back on the right track.
The problem was with automatic proxy creation by the DBContext, which interfered with the serialization.
Proxies are on by default in DBContext, you can disable them in the class constructor
this.Configuration.ProxyCreationEnabled = false;
or after creating an instance of your DBContext
using (var db = new myDBContext())
{
db.Configuration.ProxyCreationEnabled = false;
...
}
Not sure why yet, but it works. Time to go read up on that!
