Introduction

I have never liked making many errors when developing especially if they bar me from continuing with my project. One issue developers may encounter is when the CreateCoreWebView2EnvironmentWithOptions function is called with three parameters. This will result in an error, as the function does not support three arguments.t take 3 arguments”. This article will not only illustrate what the error message signifies, how it really works and why it occurs but also provide you with all the information and practical advice that you will need in order to effectively overcome this frequent obstacle in WebView2 programming.

What is WebView2?

Again, we recalled that WebView2 is a control from Microsoft used by developers to create applications with Chromium base Microsoft Edge browser to include Web Contents Besides, it can enable HTML, CSS, and JavaScript can be integrated into native applications, making it easier to develop applications that combine both web and native elements.
