Enabling C# 7 in an ASP.NET Application

ASP.NET is a powerful web development framework that allows developers to build dynamic and interactive web applications. One of the key components of ASP.NET is the C# programming language, which provides a robust and efficient way to write server-side code.

By default, ASP.NET uses a specific of C# for compiling and executing code. However, if you want to take advantage of the features and enhancements introduced in C# 7, you need to enable it in your ASP.NET application.

Step 1: Update the Target Framework

The first step to enable C# 7 in an ASP.NET application is to update the target framework. Open your project in Visual Studio and to the project properties. In the Application tab, you will find the Target Framework . Change it to “.NET Framework 4.7” or later, as C# 7 is only supported in these versions.


Step 2: Enable C# 7 Features

Once you have updated the target framework, you need to enable C# 7 features in your ASP.NET application. To do this, you need to modify the project file and add the necessary language version settings.

Open the project file (with the .csproj extension) in a text and add the following lines inside the element:


This will enable the latest language version, which includes C# 7 features, in your ASP.NET application.

Step 3: Use C# 7 Features

Now that you have enabled C# 7 in your ASP.NET application, you can using its features in your code. Let's take a look at a few examples:

// Example 1: Local Functions
void MyMethod()
    void LocalFunction()
        // Code goes here


// Example 2: Pattern Matching
void ProcessObject( obj)
    if (obj is string str)
        // Code for string 
    else if (obj is int num)
        // Code for integer objects

// Example 3: Tuples
(string, int) GetPerson()
    return ("John Doe", 30);

var person = GetPerson();
Console.WriteLine($"Name: {person.Item1}, Age: {person.Item2}");

These are just a few examples of the powerful features introduced in C# 7. By enabling C# 7 in your ASP.NET application, you can leverage these features to write cleaner and more efficient code.

Remember to build and run your application after making these changes to ensure that everything is working correctly. If you encounter any issues, double-check the target framework and language version settings.

In conclusion, enabling C# 7 in an ASP.NET application is a straightforward that involves updating the target framework, enabling C# 7 features, and using the new language features in your code. By following these steps, you can take advantage of the latest enhancements in C# and the development experience of your ASP.NET application.
