  JavaScript Code Changes Not Being Loaded in Blazor Wasm App Run in Chrome

  Jun 10, 2020 05:25 PM|CincySteve|LINK

  I am playing with a small Blazor Wasm app in which I am trying various things to better learn how they work.  Part of that includes JavaScript code that invokes Blazor methods as a way to pass object data from JS to Blazor.  My problem is that there are times when I make changes to the JS code, but the old code is what's used when I run the debugger.  I thought I understood the pattern that leads to this, but just discovered that's not so.  In particular, I had been switching between different versions of the same JS function by simply commenting out all but the one I wanted to test.  That's when it appeared the new code didn't load.  So I started making a single change to a line of code (adding a character to a string literal), which seemed to work.  But I just did that and it didn't work.  So, I'm back to needing to know what it takes to get JS code changes to be loaded?  Is this a caching problem that I can overcome with some sort of parameter?

  I am using Visual Studio Community 2019 v16.6.1 with AspNetCore v3.2.0 opening Chrome v83.0.4103.97.  My launchSettings.json are shown below.

  Thanks.  Steve
