Hi,
We run a local staging instance of our Umbraco website on a IIS webserver. Up until Umbraco 17 this has worked fine.
After i upgraded our website to Umbraco 17 i can’t start our website on IIS anymore.
.NET 10 hosting bundle is installed and running (we have other .NET 10 web apps running on this IIS server).
When i start umbraco it fails with a “HTTP Error 500.30 - ASP.NET Core app failed to start”
If i look in the event log it fails with a “System.IO.FileNotFoundException” for BloomFilter.dll:
Application: w3wp.exe
CoreCLR Version: 10.0.326.7603

If i then look in the root folder for the website, the BloomFilter.dll is right there:
I can run the website just fine on my development PC.
