How to enable Hot Reload in ASP.NET Core 7 web site project

I'm looking to enable Hot Reload to hopefully allow edits to *.cs and/or *.cshtml files without restarting debug cycle.

My original configurations in tasks.json and launch.json are as follows and everything worked (without Hot Reload)...after the site built and started, it found the log entry in terminal and launched the site with the uriFormat argument in a new/clean Chrome instance and all debugging working as expected.

Original tasks.json:

{
    "label": "debug",
    "hide": true,
    "command": "dotnet",
    "type": "process",
    "presentation": {
        "clear": true
    },
    "args": [
        "build", "${input:projectFile}",
        "/property:GenerateFullPaths=true",
        "/consoleloggerparameters:NoSummary"
    ],
    "problemMatcher": "$msCompile"
},

Original launch.json:

{
    "name": "Site",
    "presentation": {
        "order": 1,
        "group": "1. L@W Connect"
    },
    "type": "coreclr",
    "request": "launch",
    "preLaunchTask": "debug",
    "logging": {
        "moduleLoad": false
    },
    "program": "${workspaceFolder}/bin/Debug/net7.0/Nexgen.dll",
    "args": [],
    "cwd": "${workspaceFolder}",
    "stopAtEntry": false,            
    "serverReadyAction": {
        "action": "debugWithChrome",                              
        "pattern": "\\bNow listening on:\\s+(https?://\\S+)",
        "uriFormat": "%s/app/channel-home?aws=1&lp=0&datasource=1&showinspector=1&apidebug=ApiProxy_,RBLe_,DocGen_&rblcache=1&tracekatapp=0&sitekey=GOLD",
        "killOnServerStop": true
    },
    "sourceFileMap": {
        "/Views": "${workspaceFolder}/Views"
    },
    "launchSettingsProfile": "Site"            
},

I modified these files (with advice from Github Copilot) with the following.

New tasks.json:

1. New label
2. New args
3. Added isBackground
4. New presentation settings

{
    "label": "watch",
    "command": "dotnet",
    "type": "process",
    "args": [
        "watch",
        "run",
        "--project",
        "${input:projectFile}"
    ],
    "problemMatcher": "$msCompile",
    "isBackground": true,
    "presentation": {
        "reveal": "always",
        "panel": "shared"
    }
}

New launch.json:

1. serverReadyAction.action and serverReadyAction.uriFormat changed
2. Removed launchSettingsProfile (which is used by devs in Visual Studio proper)

{
    "name": "Site",
    "type": "coreclr",
    "request": "launch",
    "preLaunchTask": "watch",
    "program": "${workspaceFolder}/bin/Debug/net7.0/Nexgen.dll",
    "args": [],
    "cwd": "${workspaceFolder}",
    "stopAtEntry": false,
    "serverReadyAction": {
        "action": "openExternally",
        "pattern": "Now listening on: (https?://\\S+)",
        "uriFormat": "%s"
    },
    "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
    },
    "sourceFileMap": {
        "/Views": "${workspaceFolder}/Views"
    }
},

When I try to launch with updated settings, I get a dialog stating (even though there is a problemMatcher defined):

The task 'watch' has not exited and doesn't have a 'problemMatcher' defined. Make sure to define a problem matcher for watch tasks.

In the terminal window, my logging is as follows:

dotnet watch 🔥 Hot reload enabled. For a list of supported edits, see https://aka.ms/dotnet/hot-reload.  💡 Press "Ctrl + R" to restart.
