System.Linq.Dynamic.Core | NET Standard / .NET Core version | Database library

This is my first test with MVVM in Xamarin. I am trying to display a list of objects (examples) noted as ExampleList provided by a web API. It receives the correct data and object structure with the api & app models being pretty much 1:1.

When the page loads it presents all 9 correct elements though the text for these elements doesnt display. I know this data is correct because when an element is clicked it displays its fields of the object within a display alert.

I am certain the issue is with the markup as you can see below it is declared as: object.property , usually i would declare this as just property without the object but when doing this method the app will not compile showing the following error:

I have an application using ASP.NET Core MVC and an Angular UI framework.

I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:

Uncaught SyntaxError: Unexpected token '<'

These pages look like they are loading the index page as opposed to the .js or .css files.

Here is a snippet of the underlying runtime.js as it should be loaded into browser, it is not loaded with index.html.

I have a Kendo jquery DropdownList with Server Filtering.

I am trying to use System.Linq.Dynamic.Core with an ImmutableArray for dynamic OrderBy but I get the following exception:

Expression of type 'System.Collections.Immutable.ImmutableArray`1[$customType]' cannot be used for parameter of type 'System.Collections.Generic.IEnumerable`1[$customType]' of method 'System.Linq.IOrderedEnumerable`1[$customType] OrderByDescending[$customType,Int32](System.Collections.Generic.IEnumerable`1[$customType], System.Func`2[$customType,System.Int32])' (Parameter 'arg0')

Why is this? Have they defined specific validations for Immutable types? Normal OrderBy is perfectly capable of sorting it. Should this be submitted to them as a feature request or am I missing something obvious? Once it is cast to a List it works like a charm.

I have next LINQ-query which imitates full outer join on two datatables

I'm currently using System.Linq.Dynamic.Core to generate the SQL statements in my application. The problem is when I tried

I have a dynamic query that brings me dynamic columns (System.Linq.Dynamic.Core):

I'm trying to build a dynamic filter, where the user can search for columns in tables. To that I'm trying to use System.Linq.Dynamic.Core

I have an ad-hoc reporting system; I have no compile-time knowledge of the source type of queries or of the required fields. I could write expression trees at runtime using the System.Linq.Expressions.Expression factory methods, and invoke LINQ methods using reflection, but Dynamic LINQ is a simpler solution.

The reporting system is to allow for queries which returns the result of a LEFT JOIN. There are fields in the joined table which are NOT NULL in the database; but because this is a LEFT JOIN, those fields will contain NULL for certain records. The EF6-generated expression falls on this, because the expression projects to a non-nullable value type.

If I was doing this in compile-time LINQ, I would explicitly cast to the nullable type:
