As @Gursharan points out they are saved inside of a binary database stored in %LOCALAPPDATA%\Google\Chrome\User Data\Default\Cache.

If you want to read them from your local disk you need use a utility to read Chrome's binary cache.

Alternately you can download them using the Request URL shown in Chrome's Cache Storage.

For example:

  1. Visit following sample blazor app
  2. Open Application > Cache Storage > blazor-resources/awesome-blazor-browser in Chrome developer tools.
  3. Select a .dll resource.
  4. In the headers tab and highlight the Request URL up until the .dll extension (highlighted in yellow below)
  5. Right click and choose Go To (shown in the bottom screen shot)
  6. If the assembly is signed and trusted it will download automatically. For example, netstandard.dll. Otherwise you need to click keep in the permissions prompt.

You can try this utility - https://www.nirsoft.net/utils/chrome_cache_view.html

On windows Chrome cache location is - C:\Users\%USERNAME%\AppData\Local\Google\Chrome\User Data\Default\Cache

This utility work with latest Microsoft Edge for Chrome also. It's cache location on windows is - C:\Users\%USERNAME%\AppData\Local\Microsoft\Edge\User Data\Default\Cache

The .dll files will be at the project folder, IIS Express runs the project directly from there, e.g. if on the Developers tool(F12) > Application tab > Cache Storage you see something like /_framework/_bin/Blazor%20WebAssembly.dll.sha256-dTdRmYzYOZYhTcSkqvmzcmpD/Pi03agjQ4oZTOgt8o8= in the name, then it'll be found here when debugging:

<project root>\bin\Debug\netstandard2.1\wwwroot\_framework\_bin
