Selenium C# - setting profile path

I want to use a specific firefox profile stored in a folder.
My code so far:
IWebDriver driver;
string pathToCurrentUserProfiles = #"C:\FirefoxProfile\";
string[] pathsToProfiles = Directory.GetDirectories(pathToCurrentUserProfiles, "*.default");
FirefoxProfile profile = new FirefoxProfile(pathsToProfiles[0]);
driver = new FirefoxDriver(profile);
driver.Manage().Timeouts().PageLoad = TimeSpan.FromSeconds(10);
driver.Navigate().GoToUrl("https://localhost");
Visual Studio though shows me this error:
Error CS1503 Argument 1: cannot convert from 'OpenQA.Selenium.Firefox.FirefoxProfile' to 'OpenQA.Selenium.Firefox.FirefoxOptions'

You need to create a FirefoxOptions object and set the Profile property:
FirefoxProfile profile = new FirefoxProfile(pathsToProfiles[0]);
FirefoxOptions options = new FirefoxOptions()
{
Profile = profile
};
driver = new FirefoxDriver(options);
You can infer this solution by looking at the arguments that the FirefoxDriver constructor accepts.

How to retrieve a list of subnets for launching a Fargate task?

I'm using the AWS SDK with C# in Visual Studio 2017, and have a prototype working which launches a Fargate service in ECS. As part of the setup, you instantiate a CreateServiceRequest object which requires a NetworkConfiguration.AwsVpcConfiguration setting with SecurityGroups and Subnets.
var request = new CreateServiceRequest();
request.ServiceName = "myService";
request.TaskDefinition = "myTask"; // family[:revision] of the task definition to use
request.ClientToken = Guid.NewGuid().ToString().Replace("-", ""); // max 32 characters!
request.Cluster = "default";
request.DesiredCount = 1;
request.LaunchType = LaunchType.FARGATE;
request.DeploymentConfiguration = new DeploymentConfiguration
{
MaximumPercent = 100,
MinimumHealthyPercent = 50
};
// configure the network and security groups for the task
List<string> securityGroups = new List<string>();
securityGroups.Add("sg-123456");
List<string> subnets = new List<string>();
subnets.Add("subnet-9b36aa97");
request.NetworkConfiguration = new NetworkConfiguration
{
AwsvpcConfiguration = new AwsVpcConfiguration
{
AssignPublicIp = AssignPublicIp.ENABLED,
SecurityGroups = securityGroups,
Subnets = subnets
}
};
When I configure a service manually via the AWS Console, they display a list of subnets from which to choose. So, I'm wondering how I might programmatically retrieve that list of subnets which are available in our VPC.
I'm searching their SDK documentation for possible solutions, any pointers to their docs or examples is appreciated!

Take a look at EC2Client, you'll find a lot of VPC-related APIs are associated with the EC2 service. Specifically check out AmazonEC2Client.DescribeSubnets(DescribeSubnetsRequest), method documentation here:
Request
Amazon.EC2.Model.DescribeSubnetsRequest
Response
Amazon.EC2.Model.DescribeSubnetsResponse
Response contains a list of Amazon.EC2.Model.Subnet that you will retrieve string property SubnetId from, when deciding which subnet to pass on to your Fargate request.
Example Usage (From the linked documentation):
var response = client.DescribeSubnets(new DescribeSubnetsRequest
{
Filters = new List<filter> {
new Filter {
Name = "vpc-id",
Values = new List<string> {
"vpc-a01106c2"
}
}
}
});
List<subnet> subnets = response.Subnets;

Pass to chromedriver capabilities as desiredCapabilities c#

I have software which does automated testing via chrome browser, but now this program failed with error message "Vector smash protection is enabled."
I've found a solution for this case, but this solution implemented via java API.
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability("chrome.switches", Arrays.asList("--incognito"));
ChromeOptions options = new ChromeOptions();
options.addArguments("test-type");
WebDriver driver = new ChromeDriver(capabilities);
How to implement a code the same as above via c#?

You need a Dictionary
// Capabilities Values
var imageSetting = new Dictionary<string, object> {{"images", 2}};
var content = new Dictionary<string, object> {{"profile.default_content_settings", imageSetting}};
var prefs = new Dictionary<string, object> {{"prefs", content}};
// List of Chromium Command Line Switches
var options = new ChromeOptions();
options.AddArguments(
"--disable-extensions",
"--disable-features",
"--disable-popup-blocking",
"--disable-settings-window");
// Add the Capabilities
var field = options.GetType().GetField("additionalCapabilities", BindingFlags.Instance | BindingFlags.NonPublic);
if (field != null)
{
var dict = field.GetValue(options) as IDictionary<string, object>;
if (dict != null) dict.Add(ChromeOptions.Capability, prefs);
}
// Create the Chrome Driver
var chromeDriver = new ChromeDriver(options);
Also you can send the driver path when you create the ChromeDriver object.

Disable images in Selenium Google ChromeDriver

How does one disable images in Google chrome when using it through Selenium and c#?
I've attempted 6 ways and none worked. I've even tried the answer on this StackOverflow question, however I think the info in it is out of date.
Chrome driver: V2.2
Chrome version: V29.0.1547.66 m
Selenium: V2.35
All the attempts I've made don't cause exceptions, they run normally but still display images:
Attempt 1:
ChromeOptions co = new ChromeOptions();
co.AddArgument("--disable-images");
IWebDriver driver = new ChromeDriver(co);
Attempt 2:
DesiredCapabilities capabilities = DesiredCapabilities.Chrome();
capabilities.SetCapability("chrome.switches", new string[1] { "disable-images" });
Attempt 3:
ChromeOptions co = new ChromeOptions();
co.AddAdditionalCapability("chrome.switches", new string[1] { "disable-images" });
Attempt 4:
var imageSetting = new Dictionary<string, object>();
imageSetting.Add("images", 2);
Dictionary<string, object> content = new Dictionary<string, object>();
content.Add("profile.default_content_settings", imageSetting);
var prefs = new Dictionary<string, object>();
prefs.Add("prefs", content);
var options = new ChromeOptions();
var field = options.GetType().GetField("additionalCapabilities", BindingFlags.Instance | BindingFlags.NonPublic);
if (field != null)
{
var dict = field.GetValue(options) as IDictionary<string, object>;
if (dict != null)
dict.Add(ChromeOptions.Capability, prefs);
}
Attempt 5:
ChromeOptions options = new ChromeOptions();
options.AddAdditionalCapability("profile.default_content_settings", 2);
Attempt 6:
Dictionary<String, Object> contentSettings = new Dictionary<String, Object>();
contentSettings.Add("images", 2);
Dictionary<String, Object> preferences = new Dictionary<String, Object>();
preferences.Add("profile.default_content_settings", contentSettings);
DesiredCapabilities caps = DesiredCapabilities.Chrome();
caps.SetCapability("chrome.prefs", preferences);

This is my solution
IWebDriver driver;
ChromeOptions options = new ChromeOptions();
options.AddUserProfilePreference("profile.default_content_setting_values.images", 2);
driver = new ChromeDriver(options);

You should use --blink-settings instead of --disable-images by:
options.add_argument('--blink-settings=imagesEnabled=false')
which also works in headless mode. Setting profile doesn't work in headless mode. You can verify it by screenshot:
driver.get_screenshot_as_file('headless.png')
Note: I was using python with selenium, but I think it should be easy to transfer to c#.

For your method 1-3, I don't see a Chrome switch called --disable-images listed here. So even if the code snippets are correct, they won't work no matter what. Where did you get that switch? Any references?
For the methods 4-6, I assume you got the idea from this chromdriver issue. I don't know if this {'profile.default_content_settings': {'images': 2}} is still valid or not, but you can give it a try with the following code (which was originally the answer to How to set Chrome preferences using Selenium Webdriver .NET binding?, answer provided by Martin Devillers).
public class ChromeOptionsWithPrefs: ChromeOptions {
public Dictionary<string,object> prefs { get; set; }
}
public static void Initialize() {
var options = new ChromeOptionsWithPrefs();
options.prefs = new Dictionary<string, object> {
{ "profile.default_content_settings", new Dictionary<string, object>() { "images", 2 } }
};
var driver = new ChromeDriver(options);
}

Use http://chrome-extension-downloader.com/ to download the "Block Image" extension (https://chrome.google.com/webstore/detail/block-image/pehaalcefcjfccdpbckoablngfkfgfgj?hl=en-GB). The extension prevents the image from being downloaded in the first place. Now it's just a matter of loading it using the following statement:
var options = new ChromeOptions();
//use the block image extension to prevent images from downloading.
options.AddExtension("Block-image_v1.0.crx");
var driver = new ChromeDriver(options);

An easier approach would be solely:
ChromeOptions options = new ChromeOptions();
options.addArguments("headless","--blink-settings=imagesEnabled=false");

I found out simple solution. This idea referred from Python:Disable images in Selenium Google ChromeDriver
var service = ChromeDriverService.CreateDefaultService(#WebDriverPath);
var options = net ChromeOptions();
options.AddUserProfilePreference("profile.managed_default_content_settings.images", 2);
IWebDriver Driver = new ChromeDriver(service, options);

I recommend that you create a new profile, customize this profile so that it does not load the images, and use this profile as a chromeOption to set up your driver.

Azure cache programatic configuration results in ErrorCode ERRCA0029 SubStatus ES0001 Authorization token passed by user Invalid

I am trying Proof of Concepts based on code at http://msdn.microsoft.com/en-us/library/windowsazure/gg618003. This cache is accesible if I use app.config settings. When I switched the application to use programatic configuration, I consistently get this error. I have already tried Azure cache programatically configuration fail to verify and many other solutions to no avail.
Here's my code snippet.
{code}
String acsKey = "AcsKey removed intentionaly";
DataCacheFactoryConfiguration cacheFactoryConfiguration;
DataCacheSecurity dataCacheSecurity;
DataCacheServerEndpoint[] serverEndpoints = new DataCacheServerEndpoint[1];
SecureString secureAcsKey = new SecureString();
serverEndpoints[0] = new DataCacheServerEndpoint("EndPont removed intentionaly", 22243);
//
// Create SecureString from string
//
foreach (char keyChar in acsKey)
{
secureAcsKey.AppendChar(keyChar);
}
secureAcsKey.MakeReadOnly();
dataCacheSecurity = new DataCacheSecurity(secureAcsKey);
//
// Initialize Factory Configuration
//
cacheFactoryConfiguration = new DataCacheFactoryConfiguration(); // This line throws exception. Note that the key is yet to be assigned to SecurityProperties as per documentation.
cacheFactoryConfiguration.Servers = serverEndpoints;
cacheFactoryConfiguration.SecurityProperties = dataCacheSecurity;
_cacheFactory = new DataCacheFactory(cacheFactoryConfiguration);
_cache = _cacheFactory.GetDefaultCache();
{code}

Try passing all the params at creation and not post creation?
var configFactory = new DataCacheFactoryConfiguration
{
Servers =
new List<DataCacheServerEndpoint>
{new DataCacheServerEndpoint(cacheServer, cachePort)},
SecurityProperties =
new DataCacheSecurity(Encryption.CreateSecureString(cacheAuthorization),
true)
};
