This issue has been moved from a ticket on Developer Community.


[severity:I'm unable to use this version]
One of our projects gets hung up about 3/4th the way through a publish of a Blazor WebAssembly AOT publish. The error and log are below:

Our project does not directly reference Microsoft.AspNetCore.Razor.Language.dll AFAICT.

Same issue here. I can compile using aot. However, when I include my telerik control and use aot. I get this error.
