System.InvalidProgramException Error C# when creating CIMSession

Trying to remotly connect to another PC's WMI but when creating the CimSession I get the following error
System.InvalidProgramException:'Common Launguage Runtime detexted an invalid program'
The code I am running is as follows
using System;
using System.Text;
using System.Threading;
using Microsoft.Management.Infrastructure;
using Microsoft.Management.Infrastructure.Options;
using System.Security;
namespace SMAPIQuery
{
class Program
{
static void Main()
{
string computer = "ComputerB";
DComSessionOptions DComOptions = new DComSessionOptions();
DComOptions.Impersonation = ImpersonationType.Impersonate;
CimSession Session = CimSession.Create(computer, DComOptions);
}
}
}
Unsure as to what throws this error or how to get around it

The issue was I was using .Net Core and not .Net Framework

C# ScrapySharp 'System.Net.CookieException: 'The 'Name'='HttpOnly, NID' part of the cookie is invalid.'

So i'm facing an unexpected issue with my code. For some reason, I am unable to download & print the links out of my Google search... Help is much appreciated as I'm really not sure what is going on here... I am also using the DotNET SDK
using System;
using System.Threading.Tasks;
using ScrapySharp;
using ScrapySharp.Extensions;
using ScrapySharp.Network;
using static System.Console;
namespace Test
{
class Program
{
static async Task Main(string[] args)
{
var query = "scrapysharp";
Console.WriteLine($"Searching '{query}' on google");
var browser = new ScrapingBrowser();
browser.UseDefaultCookiesParser = false;
var resultsPage = await browser.NavigateToPageAsync(new Uri($"https://www.google.fr/search?q={query}"));
Console.WriteLine($"Results");
foreach (var link in resultsPage.Html.CssSelect("h3.r a"))
{
Console.WriteLine($"- {link.InnerText}");
}
}
}
Error:
System.Net.CookieException: 'The 'Name'='HttpOnly, NID' part of the cookie is invalid.'

I was facing the same issue, the quick workaround for me was bellow one line code.
browser.IgnoreCookies = true;
Leave everything else as is, add this line after the line where you are creating browser object and try it out.

Program not responding from SearchListResponse

I am trying to gather data of YouTube videos using a Winforms app. When I call YTSearch() method as seen below, The program stops responding when it gets to
var slResponse = await slRequest.ExecuteAsync();
The request is started, but does not stop, and is neither finished, nor triggering the catch on a try catch. I have managed to get the exact same thing working using a Discord bot, using Discord.NET. In the output is
Exception thrown: 'Google.GoogleApiException' in Google.Apis.dll
Exception thrown: 'Google.GoogleApiException' in mscorlib.dll
Exception thrown: 'Google.GoogleApiException' in mscorlib.dll`
Libraries:
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using System.Windows.Forms;
using Google.Apis.YouTube.v3;
using Google.Apis.Services;
using System.Diagnostics;
Method:
public async Task<List<Video>> YTSearch(string query)
{
string ytAPI = APIKEY; // Ommitted
var ytService = new YouTubeService(new BaseClientService.Initializer()
{
ApiKey = ytAPI,
ApplicationName = "YouTubeDownloader"
});
var slRequest = ytService.Search.List("snipper");
slRequest.Q = query;
slRequest.MaxResults = 10;
var slResponse = await slRequest.ExecuteAsync();
List<Video> vidList = new List<Video>();
return vidList;
}
Call:
private void btnSearch_Click(object sender, EventArgs e)
{
List<Video> vidList = YTSearch(txtSearch.Text).Result;
}

I haven't tested this, but I'm fairly sure you need to use ConfigureAwait(false). So in your YTSearch method you need to use the line:
var slResponse = await slRequest.ExecuteAsync().ConfigureAwait(false);
This is required because you are blocking for the result in the button handler, by using .Result.
This MSDN article is a little old, but explains the problem.

First off you have a small typo you should fix that is unrelated to your error. The first parameter is part valid values are
contentDetails: 2
id: 0
snippet: 2
You have snipper
It isn't clear that this is the issue as the error you are getting isn't related to the API.
The issue sounds more like a problem with the dll. I would try to reimport the nuget package make sure you are using.net 4.5 in your project

How do I make an Xpath element visible using Selenium?

An unhandled exception of type OpenQA.Selenium.InvalidSelectorException occurred in WebDriver.dll
Additional information: invalid selector: Unable to locate an element with the xpath expression //*[#id='hdtb-msb']/div[1]/div[4]/a) because of the following error:
SyntaxError: Failed to execute 'evaluate' on 'Document': The string '//*[#id='hdtb-msb']/div[1]/div[4]/a)' is not a valid XPath expression.
I have tried finding the element through Class as well -- didn't seem to be working. Then remembered that it could be a time issue. After reading several articles/posts, I am not sure what else to try.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
namespace Webdemo2
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver = new ChromeDriver();
driver.Url = "http://gooogle.com";
var searchbox = driver.FindElement(By.Id("lst-ib"));
searchbox.SendKeys("Pluralsight");
//adding timeout
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(7));
var images = driver.FindElement(By.XPath("//*[#id='hdtb-msb']/div[1]/div[4]/a)"));
images.Click();
}
}
}

At the end of your xpath expression:
/a)
I think you need to take that closing parenthesis out of the expression.

Im getting exception Typeload what the exception can be?

I added as reference 3 dll's: Google.Apis , Google.Apis.Translate.v2 , System.Runtime.Serialization
In Form1 i have one line:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Translator.translate(new TranslateInput());
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
Now the error the exception is on the first line in the class Translator:
The line that throw the error is: var service = new TranslateService { Key = GetApiKey() };
The class code is:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Web;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using Google.Apis.Util;
using Google.Apis.Translate.v2;
using Google.Apis.Translate.v2.Data;
using TranslationsResource = Google.Apis.Translate.v2.Data.TranslationsResource;
public class Translator
{
public static string translate(TranslateInput input)
{
// Create the service.
var service = new TranslateService { Key = GetApiKey() };
string translationResult = "";
// Execute the first translation request.
Console.WriteLine("Translating to '" + input.TargetLanguage + "' ...");
TranslationsListResponse response = service.Translations.List(input.SourceText, input.TargetLanguage).Fetch();
var translations = new List<string>();
foreach (TranslationsResource translation in response.Translations)
{
translationResult = translation.TranslatedText;
}
return translationResult;
}
private static string GetApiKey()
{
return "AIzaSyCjxMe6RKHZzd7xSfSh2pEsBqUdXYm5tA8"; // Enter Your Key
}
}
/// <summary>
/// User input for this example.
/// </summary>
[Description("input")]
public class TranslateInput
{
[Description("text to translate")]
public string SourceText = "Who ate my candy?";
[Description("target language")]
public string TargetLanguage = "fr";
}
The error is:
Could not load type 'Google.Apis.Discovery.FactoryParameterV1_0' from assembly 'Google.Apis, Version=1.1.4497.35846, Culture=neutral, PublicKeyToken=null'.
Tried to google for help and also tried to change the project type to x64 platform but it didnt help. So i put it back on x86
I have windows 7 64bit visual studio c# 2010 pro .net 4.0 profile client.
Cant figure out what is the error ?

This error as reported in the above-posted messages is due to a local copy in the bin\Debug folder of your solution or project. Even though you attempt to clean your solution, such copies will persist to exist.
In order to avoid this to happen, you have to force Visual Studio to refer to the correct DLL by adding reference paths within a project properties. Unfortunately, if you got several projects within your solutions, you will have to set the reference paths for the projects one after another until completed.
Should you wish to know how to setup reference paths follow these simple instructions:
1.Select your project, right-click, then click "Properties";
2.In the project properties, click "Reference Paths";
3.Folder, type or browse to the right location of your DLL, click [Add Folder].
You will need to perform these steps for as many different locations you may have for each of your DLLs. Consider setting an output path under the Build tab of the same project properties, so that you may output your DLLs in the same directory for each of them, thus assuring you to find all the latest builds under the same location, simplifying forward your referencing.
Note this can only be one reason for this error. But it is sure that is has to do something with a wrong copy of the mentioned assembly.
