Hands-on with MCP Resources in Visual Studio

In the first post of this series, we explored what MCP resources are and why they're the overlooked piece of the MCP puzzle. In a second post we showed how to use MCP resources in Visual Studio Code. Before I continue with a next post on building your own MCP server, I first want to show you how Visual Studio handles MCP resources.

Setting up your MCP server with resources in Visual Studio.

Let's start by installing an MCP server that provides resources. We'll use the GitHub MCP Server as our example because it's widely used and demonstrates several resource patterns.

We’ll use an mcp.json file to configure our mcp server:

  • Create .vscode/mcp.json in your workspace root
  • Add your server configuration:
  • Save the file—Visual Studio will detect it and try to load the MCP server.
  • If you now try to use this MCP server, you’ll notice that it doesn’t work yet.
  • This is because we first need to authenticate and fetch an OAUTH token.
  • Click on the … next to the MCP server and click on the Authentication option
  • On the Authentication popup, click on Authenticate.

Using MCP resources

Once you have an MCP server installed and running, let's explore its resources.

  • Click on the + icon in the chat menu and choose MCP resources:

 

  • Choose the MCP resource template you want to use and provide the necessary parameters
    • Remark: Notice that the path used in the Github MCP server is case sensitive!

 

  • Now our agent can use this resource in the same way as a local resource.

That’s it!

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...
