Filtering by dropdown value
Why doesn't below code work?
```
var childrenInCat = Model.Parent.Children.Where<BlogPost>(x => x.blogPostCategory = category);
```
I get "Type IEnumerable is Defined in an assembly that is not reference.

Top of the page reads:
```
@inherits UmbracoViewPage<BlogPost>
```
I am using the v8 compatible notation.

I've tried to follow documentation by appears that the only overload for Where I can use is Where<>(), documentation shows all examples with Where()

https://our.umbraco.com/Documentation/Reference/Querying/IPublishedContent/Collections

Really lost at this point.

I guess you have tried removing the <BlogPost> part? That should be inferred from the Children type which is IEnumerable<IPublishedContent>. If you want to cast them to BlogPost you can do:
```
Model.Parent.Children.Where(x => x.Id == 123).Select(x=> new BlogPost(x));
```
If you want to filter the children by doctype you can do:
```
Model.Parent.Children.OfType<BlogPost>()
```

Ok so this turned out to be some sort of .NET Visual Studio issue.

I've Googled the exception what was showing up when debugging the page.

you must add a reference to assembly 'netstandard, version=2.0.0.0, culture=neutral, publickeytoken=cc7b13ffcd2ddd51'.

Solution was to add following to Web.Config
```
<assemblies>
        <add assembly="netstandard, Version=2.0.0.0, Culture=neutral, 
            PublicKeyToken=cc7b13ffcd2ddd51"/>
```
