Hi,  
I wanted to test apm .net but I couldn't run the MVC [ASP.NET](http://ASP.NET) .net framework (with Profiler Auto instrumentation). Do I need any code changes?

I followed the general steps here for IIS10

> **[Profiler Auto instrumentation | APM .NET Agent Reference \[1.x\] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup-auto-instrumentation.html)**

 ![app-pool](https://us1.discourse-cdn.com/elastic/original/3X/5/d/5d89764abf6b9b4499664855d64296e5754faed5.png)

**Kibana version** : 8.5.1

**Elasticsearch version** : 8.5.1

**APM Server version** : elastic\_apm\_profiler\_1.18.0

Hi @aysekisik_kisilan,

could you give me more details on the issue you are experiencing?  
Do you see anything in Kibana (e.g. Service, metrics but no transactions) or don't you see anything?

The [troubleshooting page](https://www.elastic.co/guide/en/apm/agent/dotnet/current/troubleshooting.html) explains how to collect agent logs. If you could attach those, this would be helpful.

Thank you

Hi @aysekisik_kisilan,

it looks like you are using `DOTNET_STARTUP_HOOKS` as well.  
However, `DOTNET_STARTUP_HOOKS` is not yet ready for .NET 7 (see this [issue](https://github.com/elastic/apm-agent-dotnet/issues/1900)).  
However, we are working on that at the moment and a new agent release with .NET 7 support should be available soon.

Are you using the profiler as well? You should not use both approaches (`DOTNET_STARTUP_HOOKS` and the profiler) in the same process.

I'm sorry for the late reply,

I was trying in net 6 for testing. DOTNET\_STARTUP\_HOOKS then for .NET 7 I guess. thank you.  
I saw this here ([zero code change setup](https://www.elastic.co/guide/en/apm/agent/dotnet/current/setup-dotnet-net-core.html) )(.NET5+)

2).NET Framework 4.6.1+

I am using a simple application for IIS. I was using this for the .NET Framework 4.6.1+  
(IIS 10), but Services, traces, and metrics do not show up on APM server.

```auto
$appcmd = "$($env:systemroot)\system32\inetsrv\AppCmd.exe"
$appPool = "<application-pool>" 
$profilerHomeDir = "<unzipped directory>" 
$environment = @{
  COR_ENABLE_PROFILING = "1"
  COR_PROFILER = "{FA65FE15-F085-4681-9B20-95E04F6C03CC}"
  COR_PROFILER_PATH = "$profilerHomeDir\elastic_apm_profiler.dll"
  ELASTIC_APM_PROFILER_HOME = "$profilerHomeDir"
  ELASTIC_APM_PROFILER_INTEGRATIONS = "$profilerHomeDir\integrations.yml"
  COMPlus_LoaderOptimization = "1" 
}

$environment.Keys | ForEach-Object {
  & $appcmd set config -section:system.applicationHost/applicationPools /+"[name='$appPool'].environmentVariables.[name='$_',value='$($environment[$_])']"
}

```

This error

`[system.application][error] .NET Runtime version 4.0.30319.0 - Failed to load profiler during CoCreateInstance. Profiler CLSID: '{FA65FE15-F085-4681-9B20-95E04F6C03CC}'. HRESULT: 0x800700c1. Process ID (decimal): 3656. Message ID: [0x2504].`

Hi @aysekisik_kisilan,

is your application 32-bit by any chance? The Profiler only works for 64-bit applications.

If you need this feature (32-bit), here is a [GitHub issue](https://github.com/elastic/apm-agent-dotnet/issues/1866) for it. If you leave a comment, this helps us aligning our priorities.
