Folk, I finally found a simple way of naming certain Url paths as exempt
from Blazor Wasm routing. The Azure App Service has several virtual
directories which work in the traditional way:

However, if you deploy a Blazor Wasm app into the / root folder, then it
installs a Web.config file into the root with the following rewrite rule
that hijacks every request::
<rule name="Serve subdir">
<match url=".*" />
<action type="Rewrite" url="wwwroot\{R:0}" />
</rule>
To allow the virtual directories to work as usual, insert rules like this
before the previous one:
<rule name="Skip Test1" stopProcessing="true">
<match url="cadmium" />
<action type="None" />
</rule>
You can combine multiple <conditions> to make it less verbose. It took
hours of reading and frustrating experiments to get those 4 lines of xml
correct. Now...how do you alter the default Web.config that is deployed
with the Blazor app so you don't have to edit it manually every time?
