Hi,

I want to implement apm for dotnet 4.5 framework. Have found from below link that its not supported by agent.

[https://www.elastic.co/guide/en/apm/agent/dotnet/current/supported-technologies.html](https://www.elastic.co/guide/en/apm/agent/dotnet/current/supported-technologies.html)

Is there anyway to get it working.

Regards,  
Bryce Fernandes.

Hi @Bryce_Fernandes,

no, unfortunately there isn't. I know some super old `4.5.x` version is still supported by Microsoft, however the downside of supporting that old version would not be worth the effort on our side. So at this point `4.6.x` is the oldest which is supported by the agent.

From the technical point of view: the agent uses some types which are not supported on `4.5`, so we couldn't compile it for that version.
