Install - .NET Core Windows Dynamic Agent started as an IIS Site

.NET Core Compatibility

vFunction supports C# .NET Core versions 3.0, 6.0. 7.0, 8.0 applications.

Application Pool Prerequisites

The vFunction Agent requires a distinct Application Pool to be created for the Application if the current Application Pool is used by multiple Applications. Follow these steps to create a new Application Pool if needed.

Installation Workflow

  1. Ensure Prerequisites are met
  2. Download the vFunction Windows Controller Installation ZIP
  3. RDP to the Windows Server as the user who runs the Application
  4. Move the Installation ZIP to the location on the Windows Server where vFunction should run
  5. Extract the vFunction Installation Package
  6. Open PowerShell
  7. Add Environment Variables for the vFunction Dynamic Agent and install the Agent
### Replace the $CHANGE_ME values with the Required Configuration Settings. For detailed Settings explanations, see:
### https://kb.vfunction.com/installations/configurable-settings/mono-dynamic-agent/dotnet/windows/#required
### Replace $BASE_DIR with the Windows location where the vFunction Installation ZIP was extracted
powershell -NoProfile -ExecutionPolicy unrestricted -Command "
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_CONTROLLER_NAME -Value '$CHANGE_ME';
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_CONTROLLER_HOST -Value '$CHANGE_ME';
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_CONTROLLER_SERVER_APPLICATION_SERVER_USERNAME -Value '$CHANGE_ME';
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_SERVER_APPLICATION_SERVER_PASSWORD -Value '$CHANGE_ME';
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_SERVER_APPLICATION_NAME -Value '$CHANGE_ME';
New-Item -Path Env:\VF_CONTROLLER_DEFAULT_DOTNET_SERVER_APPLICATION_INCLUDE_CLASSES -Value '$CHANGE_ME';
$BASE_DIR\controller-installation\install.ps1 -instance default-dotnet -scriptMode true"
  1. Open the C:\Windows\System32\inetsrv\config\applicationHost.config to create the Environment Variables that hook the vFunction Dynamic Agent into the Application
  2. Search for the term applicationPools in the applicationHost.config. Find the relevant Application Pool, such as DefaultAppPool, to be modified
### Replace $BASE_DIR with the Windows location where the vFunction Installation ZIP was extracted
    <add name="DefaultAppPool" autoStart="true">
        <environmentVariables>
            <add name="VF_AGENT_CONF_LOCATION" value="$BASE_DIR\config\agent\instances\default-dotnet\conf.json" />
            <add name="CORECLR_PROFILER_PATH_64" value="$BASE_DIR\agent\vfagent.net.dll" />
            <add name="CORECLR_PROFILER_PATH_32" value="$BASE_DIR\agent\vfagent.net.x86.dll" />
            <add name="CORECLR_ENABLE_PROFILING" value="1" />
            <add name="CORECLR_PROFILER" value="{cd7d4b53-96c8-4552-9c11-6e41df8eab8a}" />
            <add name="DOTNET_TailCallOpt" value="0"/>
        </environmentVariables>
    </add>
  1. Recycle the relevant Application Pool from IIS Manager to affect only this Site. Or, run iisreset to restart all Sites
  2. Confirm that the Application comes up and functions as expected. If any issues arise:
  1. Start Learning in the vFunction UI
  2. Validate the vFunction data collectioncollecting data
