Hello,

I'm trying to make my app culture invariant by adding the InvariantGlobalization = true property in the project file

```auto
<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
	<GenerateDocumentationFile>true</GenerateDocumentationFile>
	<NoWarn>$(NoWarn);1591</NoWarn>
	<DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
	<PlatformTarget>x64</PlatformTarget>
	<InvariantGlobalization>true</InvariantGlobalization>
  </PropertyGroup>

```

When I did, I start getting these errors on app-start, and can't figure out where to fix this

```auto
[07:21:15 ERR] {SystemTotalCpuProvider} Error instantiating 'Processor' performance counter
System.Globalization.CultureNotFoundException: Only the invariant culture is supported in globalization-invariant mode. See https://aka.ms/GlobalizationInvariantMode for more information. (Parameter 'culture')

```

Any ideas?

Hi @jimmie,

thanks for bringing this to our attention.

Would you mind creating a [GitHub issue](https://github.com/elastic/apm-agent-dotnet/issues/new/choose) for that?  
That way can consider the problem in our planning and triaging sessions and you can better follow the progress.

Thanks,  
Wolfgang
