Perhaps I am not especially observant or maybe, just maybe, Visual Studio 2019 lacks code snippets for TryParse. I created two for use with Visual Basic .NET.

I imported these via the code snippet manager, which may be accessed either through the View menu or by pressing the following key combination in rapid succession: CTRL + K, CTRL + B
