Is it possible to install a .NET application on Windows Sandbox?

Question

I'm using Windows Sandbox currently and it looks like there's no way to run a .NET application. Although the Sandbox has .NET 4.8 installed, when I try to run a downloaded .NET desktop application it complains that the runtime is not available.

Trying to install a specific runtime (4.7.2 is what the download takes me to) gives the error above.

So is there some way to run .NET applications on the Sandbox?

it's a bug introduced with KB4495620 and (again) KB4502584. See also this page on Redddit .
