Converting liquid template to razor.

[rwxzig]

How would the filename look like so that the template engine will pick it up?

I am trying to convert the blog template from liquid to razor and I am stuck at this two lines (for now):

{{ Model.Content.BlogPost-Category | shape_render }}
{{ Model.Content.BlogPost-Tags | shape_render }} 

I have BlogPost-Category.cshtml and BlogPost-Tags.cshtml but I still get this error:

RuntimeBinderException: Cannot perform runtime binding on a null reference
CallSite.Target(Closure , CallSite , object )
System.Dynamic.UpdateDelegates.UpdateAndExecute1<T0, TRet>(CallSite site, T0 arg0)
AspNetCoreGeneratedDocument.Views_Content_BlogPost.ExecuteAsync() in Content-BlogPost.cshtml
+
@await DisplayAsync(Model.Content.BlogPost.Category)

I also tried BlogPost.Category.cshtml and BlogPost.Tags.cshtml but without result.

This is the object if it helps:

{"Subtitle": {
    "Text": "Problems look mighty small from 150 miles up"
  },
  "Image": {
    "Paths": [
      "post-bg.jpg"
    ],
    "MediaTexts": [
      ""
    ],
    "Anchors": [
      {
        "X": 0.5,
        "Y": 0.5
      }
    ]
  },
  "Tags": {
    "TermContentItemIds": [
      "45aqajy6ngm6c2rstpj765xvx7",
      "47pv6mxcd73j95pphm7zh4bjdn",
      "46cp0wkw4sc2wx15rjkv3r2q4b"
    ],
    "TaxonomyContentItemId": "459m6ykspchd9tbv75en8xsym1",
    "TagNames": [
      "Earth",
      "Exploration",
      "Space"
    ]
  },
  "Category": {
    "TermContentItemIds": [
      "42tb4enhpzcjvzkmftdk2tn7dy"
    ],
    "TaxonomyContentItemId": "4756rg85hv9yd1fya5cbg73n54"
  }
}

Or is it something else that is causing the error?

Edit 1:
Also I am trying to remove some parts same as from the liquid template:

remove: 
{% shape_remove_item Model.Content "HtmlBodyPart" %}
{% shape_remove_item Model.Content "Blog-Image" %}

{{ Model.Content | shape_render }}
add instead:
@Model.ContentItem.Content.Remove("HtmlBodyPart")
@Model.ContentItem.Content.Blog.Remove("Image")
@await DisplayAsync(Model.Content)

But instead I get: True True and the entire content from the blog item.
Apparently it returns some boolean variable, but isn't .Remove method supposed to remove some body parts of the Model?
