the diagnosticLogging was key to helping me figure it out.

Microsoft please make this easier... Really, vscode could have figured this out or at least guided me more on the process.

Anyway here's what finally worked in my launch.json:

"url": "http://localhost:8080/",
"sourceMaps": true,
"webRoot": "${workspaceRoot}",
"diagnosticLogging": true,
"sourceMapPathOverrides": { "webpack:///src/*": "${workspaceRoot}/src/*" }

my tsconfig.json:

"outDir": "dist",
"sourceMap": true

my webpack.config.js:

output: {
   path: 'dist/dev',
   filename: '[name].js'
},
...
module: {
    loaders: [...],
    preLoaders: [{
        test: /\.js$/,
        loader: "source-map-loader"
    }]
}
...
plugins: [
    new webpack.SourceMapDevToolPlugin(),
    ...
],
devtool: "cheap-module-eval-source-map",
