This demo shows yoAnime Studio Web Surfaces running live inside Microsoft PowerPoint.
Instead of embedding a fragile ActiveX control, yoAnime uses a hybrid architecture: a normal editable PowerPoint shape acts as the placeholder, while a synchronized WebView2 overlay renders the live HTML/WebGL content exactly over that shape. The placeholder remains selectable, movable, and resizable like any regular PowerPoint object, while yoAnime handles the live visual layer on top.
In this example, the Web Surface Gallery inserts a Morphing Particles effect powered by HTML, JavaScript, WebGL, and Three.js. yoAnime tracks the PowerPoint slide geometry, shape bounds, zoom, pane layout, and slide changes, then keeps the web surface aligned with the actual PowerPoint shape.
The result is a live interactive web animation inside PowerPoint, without converting the slide into a video and without losing the editable PowerPoint workflow.
yoAnime is turning PowerPoint into a real visual engine.

![Fix Visual Studio IntelliSense Shows Errors but Compiles and Builds Successfully [SOLVED]](https://i.ytimg.com/vi/q_BlNPXNaf8/mqdefault.jpg "Fix Visual Studio IntelliSense Shows Errors but Compiles and Builds Successfully [SOLVED]
Struggling with Visual Studio showing hundreds of IntelliSense errors even though your project compiles, builds, and runs perfectly? Youre in the right place! This tutorial provides a quick, safe, and effective solution to fix these frustrating phantom errors.
In this video, I demonstrate a real-world scenario in my PowerPoint VSTO add-in project where the Error List showed 291 errors in the Build + IntelliSense view but showed zero errors and built successfully in Build Only mode. This is a common issue that can happen in any complex C# or .NET project when the Visual Studio cache becomes corrupted or outdated.
The root cause is often a stale cache stored in hidden folders within your solution. I will walk you through the simple, step-by-step process of safely locating and deleting the .vs, bin, and obj folders to force Visual Studio to regenerate them, resolving these phantom errors for good.
đź•’ TIMESTAMPS / CHAPTERS:
0:00 - Introduction: Explaining the IntelliSense Error Problem
1:04 - Proving the Build is Successful (Switching to Build Only mode)
1:58 - Explaining the Cause: Corrupted Visual Studio Cache
3:19 - Locating the Hidden .vs Folder in Windows Explorer
4:35 - The Solution: Deleting the .vs, bin, and obj Folders

đź’ˇ WHAT YOU WILL LEARN:
- How to differentiate between genuine build errors and IntelliSense cache errors.
- The purpose of the .vs, bin, and obj folders in a Visual Studio solution.
- The safe and correct procedure to clear your projects cache without losing any important data.
- How to force Visual Studio to perform a clean rebuild to fix corrupted file references.
- This solution is applicable to a wide range of C# and .NET projects, including:
- VSTO Add-ins (PowerPoint, Excel, Word, Outlook)
- WPF and WinForms Desktop Applications
- ASP.NET and .NET Core Web Applications
- Class Libraries and more.
