Seems like a regression, see: https://github.com/dotnet/razor/issues/11203

[ScarletKuro]

This is all because of this line:

MudBlazor/src/MudBlazor/Components/DataGrid/MudDataGrid.razor.cs

Line 36 in c8529ab

private PropertyInfo[] _properties = typeof(T).GetProperties();

And we are forced to add this DAM annotation to all DataGrid classes that use generic and are dependent on datagrid class and it's descendants.
Perhaps we would want to redo this feature to not have this annotation almost everywhere in the datagrid.

@ScarletKuro LGTM. Just want to check azure hosting is ready

[mikes-gh]

Because we publish self-contained the runtime on azure doesn't matter
dotnet publish ${{ inputs.project-directory }} -c Release --runtime win-x64 --self-contained -o ${{ inputs.web-app-name }}

Therefore, I am inclined to merge this and just see if dev.mudblazor.com works.
