Trying to get DataTables to work in a ASP.NET Core 2 project. When the following line of code executes, the application throws exception on OrderBy
var data = (from app in _context.Applications select app);
//Sorting
if (!(string.IsNullOrEmpty(sortColumn) && string.IsNullOrEmpty(sortColumnDir)))
{
data = data.OrderBy(sortColumn + " " + sortColumnDir);
}
The exception is:
{System.TypeInitializationException: The type initializer for 'System.Linq.Dynamic.ExpressionParser' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Is there a way to use this OrderBy in ASP.NET Core, or suggest an alternative option?
Sorry I'm a bit late to your question, but I had exactly this problem and I've just fixed it. I'm also using Core 2.0 and was using System.Linq.Dynamic and got that error when I used an OrderBy extension, but I uninstalled it and installed System.Linq.Dynamic.Core instead, and now it's working perfectly

So I'm testing out the Discord.Addons.Interactive namespace to see what it offers. So I write a little InteractiveBase that looks something like this:
public class Interactive : InteractiveBase
{
[Command("book")]
private async Task BookAsync()
{
await PagedReplyAsync(new PaginatedMessage
{
Title = "Book",
Color = HelperFunctions.GenColor(),
Pages = "This is a book".Split(" ")
});
}
}
So I run the discord bot, everything is well, and then I test out the new book command. Then all of a sudden this happens:
Discord.Commands.CommandException: Error occurred executing "book" for USERNAME#XXXX in SERVER/CHANNEL.
---> System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task`1<Discord.Rest.RestUserMessage> Discord.WebSocket.ISocketMessageChannel.SendMessageAsync(System.String, Boolean, Discord.Embed, Discord.RequestOptions)'.
I don't see what I did wrong, but if you do please tell me.
EDIT:
Someone asked for the project file so here it is:

There seems to be an issue between Discord.Addons.Interactive and Discord.Net having the right versions. That's what usually causes System.MissingMethodException

It works locally but when I tried pushing it to the testproject.io I get the above error message.
I am not able to change it to the recommend selenium web driver version.
The package you are using is not .NET Core compliant. With some restructure of the code what you need is available with
using OpenQA.Selenium.Support.UI;
Then take the code that used the SeleniumExtras wait helpers and change to use methods on your driver class such as
WebDriverWait browserWait = new WebDriverWait(driver, TimeSpan.FromSeconds(90));
browserWait.Until(driver => driver.FindElement(By.Id("logonIdentifier")).Displayed);
You could easily check the properties on the driver as well, say for the Url, such as
const string expectedUrl = "https://www.google.com";
browserWait.Until(driver => driver.Url == expectedUrl);
Then go remove the package you are no longer using from your project
dotnet remove package DotNetSeleniumExtras.WaitHelpers
Which funny enough is pretty much the homepage of https://www.selenium.dev/documentation/en/ but when you search you tend to get distracted by the SeleniumExtras project.
On Startup.cs in my Azure Function v2 project:
using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection;
using MyCompany.MyLib.Contracts; //namespace from external library
[assembly: FunctionsStartup(typeof(Startup))]
namespace Test
{
public class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
builder.Services.AddTransient(typeof(Logging.ILogger<>), typeof(Logging.Logger<>));
builder.Services.AddTransient<IUserLogic, UserLogic>();
builder.Services.AddTransient<IBillingLogic, BillingLogic>(); //---> loads up from above referenced "MyCompany.MyLib.Contracts" namespace and this namespace is from externally referenced class library but with in same solution
}
}
}
The above code with my own custom classes within function app project like "EmailLogic", "Logger" works fine.
But the moment I added up custom classes to services container like "BillingLogic" from external C# library project which is added as reference project from the existing visual studio solution it throws up below issue:
"A host error has occurred during startup operation '945918c0-af3a-4d50-ab1d-ac405d4f1c7b'. [2/3/2020 2:11:02 PM] MyFunction.FunctionApp: Could not load file or assembly 'MyCompany.MyLib.Contracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621). System.Private.CoreLib: Could not load file or assembly ''MyCompany.MyLib.Contracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"
If these lines from "referenced external projects" are removed,
using MyCompany.MyLib.Contracts;
builder.Services.AddTransient<IBillingLogic, BillingLogic>();
startup.cs works as expected but referring this external class from referenced project is must for my solution.

How to set dependencies when I use .NET Standard 2.0 DLL libraries with a .NET Framework console application?
which is on all your std libs add
<RestoreProjectStyle>PackageReference</RestoreProjectStyle>
so on both your standard libs
<PropertyGroup>
<TargetFramework>netstandard2.0</TargetFramework>
<RestoreProjectStyle>PackageReference</RestoreProjectStyle>
</PropertyGroup>
if this does not work i will delete

I want to get these to copy to my output folder so that I can reflect into the unit test DLL.
No Answer, just workaround;
This happened when reflecting into a Microsoft DLL; it seems that in .net core reflection changed a little bit and just blindly reflecting over every dll in a folder is no longer safe. Filtering the Dll by their dependency was possible, and that if how I narrow the scope; But even though I load every DLL the GetTypes will throw an error as mentioned above.
How you filter is less important than that you filter down what DLL's you look into.
Both start the same
foreach (string dll in Directory.GetFiles(path, "*.dll"))
assemblies.Add(Assembly.LoadFile(dll));
Bad code:
foreach (var assembly in assemblies)
{}
Good Code:
foreach (var assembly in assemblies.Where(a=>a.GetReferencedAssemblies().Any(x=>x.Name.Contains("YourCompanyNamespace"))))
{}
I'm attempting to create a custom FileConfigurationProvider implementation for some configuration elements in a .Net Core WebApi application.
It looks something like this..
public class MyProvider : FileConfigurationProvider
{
public MyProvider(FileConfigurationSource source) : base(source) { }
public override void Load(Stream stream)
{
try
{
// Stream reading things
}
catch
{
throw new Exception("Failed to load stream.");
}
}
}
Despite the simplicity of this example, the override of Load(Stream stream) gives me an indicator in VS2017 that there is no suitable method for override. Furthermore an additional error hint states that FileConfigurationProvider(System.IO.Stream) is not implemented.
Extracting to a delegate using ReSharper has revealed a new hint for the call to Load(Stream stream) stating that Argument type System.IO.Stream [System.IO, Version=4.1.0.0...] is not assignable to parameter of type System.IO.Stream [System.Private.CoreLib, Version=4.0.0.0...]
Despite these error hints I can still successfully build and run this code.
Can someone help me understand what is wrong here?
