Method not found: 'Void Microsoft.Framework.Logging.LoggerFactory.AddProvider

Hello,

I upgraded a Project from ASP.NET 5 Beta 7 to Beta 8 and I keep getting the following error which I am not able to solve:

    MissingMethodException: Method not found: 'Void Microsoft.AspNet.Razor.CodeGenerators.GeneratedTagHelperContext.set_HtmlEncoderPropertyName(System.String)'.

    Microsoft.AspNet.Mvc.Razor.MvcRazorHost..ctor(IChunkTreeCache chunkTreeCache, RazorPathNormalizer pathNormalizer)

I have the following packages on my project:

    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-beta8",
    "Microsoft.AspNet.Razor": "4.0.0-beta8-15575",
    "Microsoft.AspNet.Razor.Runtime": "4.0.0-beta8-15575",

Thank You,

Miguel
