Using the .NET Portability Analyzer - (.NET Standard Portability Analysis)

The .NET Portability Analyzer is a tool that analyzes the compatibility of your .NET code with different .NET implementations, such as .NET Framework, .NET Core and .NET Standard. It helps you identify code that is not compatible with .NET Standard. In this tutorial, we will discuss how to use the .NET Portability Analyzer to analyze your code and make it compatible with .NET Standard.

Syntax

The .NET Portability Analyzer can be downloaded as a NuGet package or a Visual Studio extension. Once installed, you can run the analyzer on your code to generate a report of compatibility issues.

Example

To demonstrate how to use the .NET Portability Analyzer, let's consider a simple example. Suppose we have a console application that uses the HttpWebRequest class to make HTTP requests.

using System;
using System.IO;
using System.Net;

namespace MyApp
{
  public class Program
  {
    public static void Main(string[] args)
    {
      HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://example.com");
      HttpWebResponse response = (HttpWebResponse)request.GetResponse();
      
      using (StreamReader streamReader = new StreamReader(response.GetResponseStream()))
      {
        string result = streamReader.ReadToEnd();
        Console.WriteLine(result);
      }
    }
  }
}

When we run the .NET Portability Analyzer on this code, we will see that the HttpWebRequest class is not compatible with .NET Standard. To make this code compatible with .NET Standard, we need to use the HttpClient class instead.

using System;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;

namespace MyApp
{
  public class Program
  {
    public static async Task Main(string[] args)
    {
      using (HttpClient httpClient = new HttpClient())
      {
        string result = await httpClient.GetStringAsync("https://example.com");
        Console.WriteLine(result);
      }
    }
  }
}

Explanation

The .NET Portability Analyzer works by analyzing the code and determining which API calls are not compatible with .NET Standard. It generates a report that highlights the compatibility issues, along with recommendations on how to resolve them.

In the example above, the .NET Portability Analyzer detected that the HttpWebRequest class is not compatible with .NET Standard, and recommended using the HttpClient class instead.

Use

The .NET Portability Analyzer is a useful tool for developers who want to make their code compatible with .NET Standard. By identifying compatibility issues and recommending solutions, it helps developers ensure that their code can run on different .NET implementations.

Important Points

Here are some important points to keep in mind when using the .NET Portability Analyzer:

• The analyzer is not perfect and may occasionally produce false positives or false negatives.
• The analyzer only checks for compatibility with .NET Standard, not with other .NET implementations such as .NET Framework or .NET Core.
• The analyzer can also be used to identify dependencies that are not compatible with .NET Standard.

Summary

In this tutorial, we introduced the .NET Portability Analyzer, a tool that helps developers make their code compatible with .NET Standard. We discussed the syntax, example, explanation, use, and important points of using the analyzer. With this knowledge, you can use the .NET Portability Analyzer to ensure that your code is compatible with .NET Standard and can run on different .NET implementations.
