Giving Copilot Agent in Visual Studio a try

After using the GitHub Copilot Agent mode for some time in VS Code, I finally found some time to give it a try in Visual Studio. Agent mode got introduced as part of the 17.14 release so if you are still using an older Visual Studio version, please update first.

Remark: Other interesting AI features in the same release are Next Edit Suggestions and AI comment generation.

Let’s dive in!

  • Open Visual Studio and go to the GitHub Copilot Chat window:

 

  • Click on the dropdown icon next to Ask and choose Agent:

Remark: Notice that the Edits feature has disappeared. So you only have Ask or Agent. I don’t know if the feature is still there, but at least I couldn’t find it…

  • Now we can ask the agent to perform specific tasks or let it figure out a solution based on a PRD (Product Requirement Document) or similar you’ve provided. So far so good.
  • The not-so-secret superpower of agents is that they are not limited to your IDE but can interact with the outside world. Out-of-the-box, you get access to MCP tools that can interact with GitHub:

 

  • Of course you are not limited to GitHub only and we can add other tools as well. Therefore create a .mcp.json file in your solution folder.
    • Notice the . in .mcp.json. This is not a typo!
    • The mcp configuration can be stored in multiple places. Some of these locations require .mcp.json while others require mcp.json. Don't ask me why!

 

    • In our MCP configuration we can point to multiple MCP servers. STDIO, SSE and HTTP based servers are supported.
    • After the file is saved and if the configuration is valid Github Copilot Agent will restart and the tools become available:

     

    • In case it doesn’t work, have a look at the GitHub Copilot information in the output window:

     

     

    If you prefer a video, here is a good starting point:

    .NET 8–Keyed/Named Services

    A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

    Kubernetes–Limit your environmental impact

    Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
