I have an .NET Core 2 powered API that I would like to add Hangfire to. The project is already using NLog to log to a MySQL database and it works fine, but when I try to setup and use Hangfire I get the following error:
Method not found: 'Hangfire.Logging.ILog Hangfire.Logging.LogProvider.GetCurrentClassLogger()'.
The Hangfire dashboard works, but I get that error when trying to enqueue my first job like this:
BackgroundJob.Enqueue(() => Console.WriteLine("Fire-and-forget"));
I have read the Hangfire documentation over at:
http://docs.hangfire.io/en/latest/configuration/configuring-logging.html
and it says:
Starting from Hangfire 1.3.0, you are not required to do anything, if your application already uses one of the following libraries through the reflection (so that Hangfire itself does not depend on any of them). Logging implementation is automatically chosen by checking for the presence of corresponding types in the order shown below.
That list includes NLog, so apparently I am doing something wrong.
In my csproj I have:
<PackageReference Include="Hangfire" Version="1.6.19" />
<PackageReference Include="Hangfire.MySqlStorage" Version="1.0.5" />
<PackageReference Include="MySql.Data" Version="8.0.11" />
<PackageReference Include="NLog" Version="4.5.3" />
<PackageReference Include="NLog.Web.AspNetCore" Version="4.5.2" />
In Startup.cs and ConfigureServices I have:
services.AddHangfire(config => config.UseStorage(new MySqlStorage(appSettings.GetConnectionString("HangfireConnectionString"))));
and in Configure I have:
loggerFactory.AddNLog();
env.ConfigureNLog("nlog.config");
app.UseHangfireDashboard();
app.UseHangfireServer();
My nlog.config contains:
<target name="database" xsi:type="Database" dbProvider="MySql.Data.MySqlClient.MySqlConnection, MySql.Data" connectionString="server=localhost;Database=nlog;user id=root;password=;SslMode=none;">
and it does log to the MySQL database without Hangfire, so that seems to be working.
Looking at the Nlog documentation at:
https://github.com/NLog/NLog.Web/wiki/Getting-started-with-ASP.NET-Core-2
They seem to add NLog in Program.cs instead of Startup.cs, so I tried that approach as well, but I still get the same error.
Looks like the Hangfire.MySqlStorage library was the root cause of this error. After changing to Hangfire.MySql.Core everything works great without any changes being made to NLog.

I am trying to get miniprofiler and Dapper on MySql to work together to profile sql statements.
I have managed to get miniprofiler and swagger to work together but the sql generated and executed by dapper are not intercepted for some reason, I believe this is because Miniprofiler.Current always returns null for some reason.
I was wondering if anyone else can help.
sample project is attached.
run docker compose and run api manually.
test api download => https://gofile.io/?c=Qf6boJ
1st issue was that app.UseMiniprofiler() needs to come before app.UseMvc
2nd issue was that the db connection factory must look like this:
public IDbConnection Create()
{
return new StackExchange.Profiling.Data.ProfiledDbConnection(
new MySqlConnection(_storageSettings.ConnectionString),
MiniProfiler.Current
);
}
The packages that I use are as follows:
<PackageReference Include="Dapper" Version="2.0.30" />
<PackageReference Include="MySqlConnector" Version="0.61.0" />
<PackageReference Include="Microsoft.AspNetCore" Version="2.2.0" />
<PackageReference Include="MiniProfiler.AspNetCore.Mvc" Version="4.1.0" />
In my .NET Core app I use some environments and I want to do different paths to log files for every environment.
For example,
Development - c:\logs
Staging - d\apps\logs
For every environment I have config section in appsettings.{env}.json:
"LocalPaths": {
"LogFileRootDirectory": "c:\\logs\\"
}
And part of nlog.config:
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
internalLogLevel="Warn"
internalLogFile="${logFileRootDirectory}internal-nlog.txt">
...
</nlog>
What's the best way to implement that?
You could use (NLog) variables.
e.g.
<targets>
<target name="file" xsi:type="File"
fileName="${var:mydir}/logfile.txt" ... >
and in C#
LogManager.Configuration.Variables["mydir"] = "c:\logs";
When you change the variable, the path is automatically changed - no reload needed.
See also the docs for ${var}
Update: you could change the LogManager.Configuration after:
env.ConfigureNLog("nlog.config");
e.g. your startup.cs could look like this:
public void Configure(IApplicationBuilder app, IHostingEnvironment env,
ILoggerFactory loggerFactory)
{
//add NLog to ASP.NET Core
loggerFactory.AddNLog();
//add NLog.Web
app.AddNLogWeb();
//configure nlog.config in your project root.
env.ConfigureNLog("nlog.config");
LogManager.Configuration.Variables["mydir"] = "c:\logs";
...
NLog.Extension.Logging ver. 1.4 supports ${configsetting} for reading directly from appsetting.json:
<targets>
<target name="file" xsi:type="File"
fileName="${configsetting:LocalPaths.LogFileRootDirectory}/logfile.txt" ... >
See also: https://github.com/NLog/NLog/wiki/ConfigSetting-Layout-Renderer
See also: https://github.com/NLog/NLog/wiki/Environment-specific-NLog-Logging-Configuration
As they state it on their GitHub repository:
.NET Core issues:
${basedir} isn't working will in .NET Core
LogManager.GetCurrentClassLogger() will use the filename instead of
the full class name (class name and namespace, like in NLog 4). This
will be fixed in the final of NLog 5 (after the release of NETSTANDARD
2.0)
So you can't do that right now. Maybe they will fix that in the future.
I use Visual Studio 2017 and create a new ASP.NET Core project.
I add migration for Entity Framework Core as below
add-migration "Initial Create"
and get the following error:
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework\Add-Migration' for Entity Framework 6.
Build Failed.
Do you know how to resolve this error?
UPDATE 1 - March 14, 2017 - Result received after running command
PM> dotnet ef migrations add "Initial Create"
I see the following output with error message at the end.

How I resolve this in VS 2017|2019
Remove EntityFramework (not EntityFrameworkCore) references from all projects in the solution
Open the solution folder in Explorer (Windows Explorer)
Close VS
delete folder
Open the solution again
Run update-database and the alert is gone
You cannot see '.vs' folder?
For those using the new port of Entity Framework 6.3 and later to .Net Core, there is a good chance that a solution will include both EfCore and Ef6 artifacts.
e.g. I had migrated an older EF6 repository from .Net Framework to Core, but wanted to make use of the out-of-the-box AspNet Identity Core subsystem, which uses EfCore.
Invariably, during migrations, I would aribtrarily receive errors like:
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework6\Update-Database' for Entity Framework 6.
or
Both Entity Framework 6 and Entity Framework Core are installed. The Entity Framework 6 tools are running. Use 'EntityFrameworkCore\Add-Migration' for Entity Framework Core
The solution is simple - when running migration commands, as per the warning, always qualify the commands with the fully qualified:
EntityFramework6\Add-Migration Foo
EntityFramework6\Update-Database
or
EntityFrameworkCore\Add-Migration Foo
EntityFrameworkCore\Update-Database
Note that for EF6 fans, at time of writing, the migration tools port to Core isn't quite up to scratch yet, as per here.
Similarly, if you have multiple DbContexts even in the same framework version (EfCore vs Ef6 on Core), you'll need to specify the name of the specific DbContext that you are trying to target, e.g.
EntityFramework6\Add-Migration Foo -Context BarDbContext
EntityFramework6\Add-Migration Baz -Context FooDbContext
Perhaps you have at least two projects in your solution each one using either version of EF. By issuing "Manage NuGet packages for solution..." you can verify if this is the case. Then, maybe you'd need to sacrifice the one using EF 6.x. After that you'll need to restart VS, maybe some caching prevents removing the package completely when you uninstall it.
EDIT: .. or you may live well with both of them, but read carefully the message and follow what it says...
If both Entity Framework Core and Entity Framework 6 are installed, and you wanna use The Entity Framework 6.
Use this command in the Package Manager Console:
'EntityFramework\Update-Database'.
No needs to delete or change anything. Just add **EntityFramework** before your EF6 Commands.
To add a migration for EF7 use the dotnet command: dotnet ef migrations add Initial
To update your database use the dotnet command: dotnet ef database update
Just...
Edit your project (Project -> right button -> edit) and DELETE EntityFramewok Line
DELETE a line like
<PackageReference Include="Entityframework" Version="6.2.0" />
And use ONLY EntityFramework Core
I have a simple CXF RS bundle deployed in Fuse 4.2 that works fine upon initial installation. But, when I update or re-install the bundle, the REST service in no longer accessible.
I tried a various configurations and found that using cxf-extension-osgi was the issue...
from this...
<import resource="classpath:META-INF/cxf/osgi/cxf-extension-osgi.xml"/>
to this...
<import resource="classpath:META-INF/cxf/cxf-extension-http-jetty.xml"/>
Also, I updated the address to be non-relative...ending up with this configuration (that works after bundle restarts, etc)
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-http.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-http-jetty.xml" />
<jaxrs:server id="testService" address="http://localhost:9000/">
<jaxrs:serviceBeans>
<ref bean="testBean" />
</jaxrs:serviceBeans>
</jaxrs:server>
Any idea what is causing this issue when using cxf-extension-osgi? Also, what is the trade-off when using cxf-extendsion-http-jetty instead (functional, performance, etc)?
thanks
Sorry, it seems to be error in cxf/servicemix integration. The problem is, cxf tries to register service under the address that is already used (by older version of this service).
Both REST and SOAP services are unaccessible after bundle restart/update. Restart of whole servicemix. Hovewer, when business logic is in other bundle, and the bundle with SOAP/REST service contains only interface, restart is needed only when interface has changed.
We were fighting with this error long, but unfortunatelly without effort.
I just tested this in Fuse 4.3.0-fuse-03-00 and it seems to work fine. The related issue below must have addressed my issue as well...
https://issues.apache.org/jira/browse/CXF-2947
Up until recently I had a working service using NHibernate 2.0. I have upgraded to 2.1, but now try to instantiate the ItemManager:
IItemManager manager = Container.Instance.Resolve<IItemManager>();
I get an exception:
Castle.MicroKernel.ComponentNotFoundException was unhandled by user code
Message="No component for supporting the service Distribution.WMS.OrderManagement.Business.Contracts.IItemManager was found"
The mapping in my windsor config looks like this:
<component
id="item.manager"
service="Distribution.WMS.OrderManagement.Business.Contracts.IItemManager, Distribution.WMS.OrderManagement.Business.Contracts"
type="Distribution.WMS.OrderManagement.Business.Managers.ItemManager, Distribution.WMS.OrderManagement.Business.Managers"
lifestyle="transient">
<parameters>
<repository>${som.item.repository}</repository>
</parameters>
</component>
IItemManager is in the namespace: Distribution.WMS.OrderManagement.Business.Contracts
Am I missing something simple or is there something else I must do after upgrading?
I found my answer, not an upgrade related issue. This project depends on a common library that I had to update the NHibernate reference in. Since the last time I got latest someone decided to change where the windsor config file was located so when I got latest and updated my reference it was no longer able to find my config.
