Angular 4–Visual Studio 2017 - error TS2420: Class 'MdButton' incorrectly implements interface 'CanDisable'. Property 'disabled' is missing in type 'MdButton'.

After upgrading to Angular 4, my Visual Studio turned red from all the TypeScript errors.

Some samples:

/node_modules/@angular/material/typings/button/button.d.ts(40,22): error TS2420: Class 'MdButton' incorrectly implements interface 'CanDisable'.
  Property 'disabled' is missing in type 'MdButton'.

/node_modules/@angular/material/typings/button/button.d.ts(40,39): error TS2507: Type '(new (...args: any[]) => CanDisable) & typeof MdButtonBase' is not a constructor function type.
The strange thing was, that when I used the Angular CLI and ng build(or serve) no errors appeared and everything seemed to work. 
I first tried to remove my node_modules folder and do a clean install –> didn’t help Sad smile
Then I removed my globally installed node_modules and reinstalled them as well –> didn’t help Sad smile
Then I upgraded my TypeScript version and the related Visual Studio tooling –> didn’t help Sad smile
In the end I found a solution that worked for me here, I had to update to Visual Studio 2017 Update 15.2. I don’t understand why upgrading an Angular version will get Visual Studio into trouble. I hope this experience will improve as I will become hesitant to upgrade Angular in the future.
Remark: Afterwards I noticed that a colleague already sent me an email telling me to update my Visual Studio before upgrading. Better read my mails next time… Confused smile

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         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
