Type: Bug

The problem is that suggested object parameters do not appear anymore when using the keyword New to initialize a new object, illustrated below.

var test = {
best: function(west){
this.west = west;
}
};
new test.best()

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.75.1. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

This is probably an OmniSharp issue since that extension is what provides C# support to VSCode.

This is probably an OmniSharp issue since that extension is what provides C# support to VSCode.

Hadn't thought of this yet but I rolled OmniSharp (C# Extension) back to a previous version to no avail. I've tried a lot of different settings and versions of extensions as well to no avail. Even tried an old code branch where I was certain it worked before to no avail.

Seems to have something to do with the object constructor being inside another object as putting "best" outside of "test" works and gives me parameter hints.

I think our "is this a class?" logic might not trigger on function expressions at all, not sure.
