Download image from url in C#

Simply You can use following methods.

using (WebClient client = new WebClient()) 
  {
    client.DownloadFile(new Uri(url), @"c:\temp\image35.png");

     //OR 

    client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png");
   }

If You don’t know the Format(.png, .jpeg etc) of Image

public void SaveImage(string filename, ImageFormat format) {

    WebClient client = new WebClient();
    Stream stream = client.OpenRead(imageUrl);
    Bitmap bitmap;  bitmap = new Bitmap(stream);

    if (bitmap != null) 
      bitmap.Save(filename, format);

    stream.Flush();
    stream.Close();
    client.Dispose();
}

Get CPU and Memory usage of system in C#

PerformanceCounter cpuCounter=new PerformanceCounter("Processor", "% Processor Time", "_Total");
PerformanceCounter ramCounter= new PerformanceCounter("Memory", "Available MBytes");

// The method nextValue() always returns a 0 value on the first call. So you have to call this method a second time
cpuCounter.NextValue();
Thread.Sleep(1000);
var cpuUsage = cpuCounter.NextValue();
string cpuUsageStr = string.Format("{0:f2} %",cpuUsage);

var ramAvailable = ramCounter.NextValue();
string ramAvaiableStr = string.Format("{0} MB", ramAvailable);

Problem in installing Dot Net Core 1.0.0 VS 2015 Tools Preview 2

Each time I try to install the DotNetCore.1.0.0-VS2015Tools.Preview2.exe package I get an error saying the following:

Setup Failed One or more issues caused the setup to fail. Please fix the issues and then retry setup. For more information see the log file. Setup has detected that Visual Studio 2015 Update 3 may not be completely installed. Please repair Visual Studio 2015 Update 3, then install this product again.

After changing the VS Community UpdateVersion string value from 14.0.25424 to 14.0.25420 in the registry, the installer worked fine for me
