Hi to all,

today I tried to move ‘long time’ running, 100% ok umbraco app from srv2017 to ‘new’ srv2019std (This was my first close-encounter with 2019 srv)

Umbraco per-se started ok, but LeBlender models does not get compiled.

Below is error excerpt:

System.Web.HttpCompileException (0x80004005): C:\WebSites\xxx\appplugins\leblender\editors\leblendereditor\views\base.cshtml(14): error CS0246: The type or namespace name 'ViewDataDictionary' could not be found (are you missing a using directive or an assembly reference?) at System.Web.Compilation.AssemblyBuilder.Compile()

at ASP.PageViewsPartialsgrideditorsbasecshtml.Execute() in C:\WebSites\xxx\Views\Partials\grid\editors\base.cshtml:line 20

Facts:

• Additionally installed .net framework 3.5
• By default built-in user group IIS_IUSRS was missing. I added it manually for given server name
• Added correct rights over folders for IUSR and IIS_IUSRS
• App pool recycled several times, as well as deleted App_Data folder, as well as deleted .net framework temporary directory

Am I forget something. Does anybody have any issues with this. Maybe something in web.config (was just copy from old system), maybe some other system right(s) or server feature(s)

Best regards,
