Error Occurred In Deployment Step 'Recycle IIS Application Pool' - Invalid Namespace SharePoint

Recently, we were developing a custom webpart for SharePoint 2019 On-Premise. We got the below error while deploying the solution,

Error occurred in deployment step 'Recycle IIS Application Pool': Invalid namespace

We have faced this issue in the past . We thought it was an issue in the .Net framework of the project. We tried to reduce the .Net framework to 4.5. But that didn't solve the issue this time. Then we Googled the issue and found out there were some configuration changes we need to do in the development environment.

We found out that we need to add a "IIS 6 WMI Compatibility" feature. Please follow the below steps to add the same,

• If you are using Windows server, go to server manager.

• Click on “Add Roles and Feature”

• It will open “add feature” dialog. Click next until you reach “Server Roles”.

• In that, expand “Web Server (IIS)”

• In that expand “Management Tools”

• In that expand “IIS 6 Management Compatibility”
