    Trying to run Umbraco 9 leads to ReflectionTypeLoadException - does anyone know what is going on with this?

    I am trying to run Umbraco 9, but I am getting a System.Reflection.ReflectionTypeLoadException in the services.AddUmbraco block.

    More error message: System.Reflection.ReflectionTypeLoadException HResult=0x80131602 Message=Could not load all types from "Umbraco.Examine.Lucene, Version=9.0.1.0, Culture=neutral, PublicKeyToken=null" due to LoaderExceptions

    I followed the command line way of building the site -

    dotnet new -i Umbraco.Templates

    dotnet new umbraco --name Umbraco9A1

    dotnet run

    Opening it up in VS2019 does not get me any further.

    If i 'continue' in VS i get a whole load of errors:

    First being "TypeLoadException: Method 'GetDocumentCountAsync' in type 'Umbraco.Cms.Infrastructure.Examine.LuceneIndexDiagnostics' from assembly 'Umbraco.Examine.Lucene, Version=9.0.1.0, Culture=neutral, PublicKeyToken=null' does not have an implementation."

    then

    "TypeLoadException: Method 'GetSearcher' in type 'Examine.Lucene.Providers.LuceneIndex' from assembly 'Examine.Lucene, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' does not have an implementation."

    Does anyone know what the issue is?

    Is there a seperate nuget source for Umbraco 9?

    The problem is most likely this one: https://github.com/umbraco/Umbraco-CMS/issues/11179

    There's a solution in the issue, clear caches and try again. Apologies for the inconvenience! :)
