Stored procedures are now easier to map and execute, with better support for complex return types. Developers can now bind stored procedures to strongly typed models, eliminating the need for manual SQL parsing.
How to Migrate NET 10 From Previous Versions?
Migrating to .NET 10 is a strategic decision that enhances performance, security, and long-term support. However, to ensure a smooth transition, developers must follow a structured approach to updating their applications while avoiding breaking changes.
Step 1: Check System Requirements
Before migrating, ensure your development environment meets the necessary system requirements for .NET 10. As running an application on an unsupported platform or outdated development tools may cause compatibility issues.
System Prerequisites:
- Windows 10/11, macOS (latest version), or Linux.
- Visual Studio 2022 (latest version) or JetBrains Rider.
- Docker (if working with containerized applications).
- Ensure all third-party dependencies support .NET 10.
To check the installed .NET versions on your system, run:
<![CDATA[
dotnet --list-sdks
]]>
Step 2: Install .NET 10 SDK
Once you confirm your system requirements, the next step is installing the .NET 10 SDK. You can download it from the official Microsoft website.
After installing, verify the installation by running:
dotnet –version
If successfully installed, this command will return a version number like 10.0.x.
Step 3: Update Project Files and Dependencies
If your project was built on an older .NET version (.NET 9 or older), you must update the project file (.csproj) to target .NET 10.
1. Modify the Target Framework in .csproj File
<![CDATA[Locate your .csproj file and change the <TargetFramework> property:]]>
Before (for .NET 7 or .NET 8):
<![CDATA[ <TargetFramework>net7.0</TargetFramework> ]]>
After (for .NET 10):
<![CDATA[ <TargetFramework>net10.0</TargetFramework>]]>
The above command will ensure your application runs using .NET 10.
2. Upgrade NuGet Packages
Updating dependencies is crucial to avoid compatibility issues. Run the following commands:
dotnet nuget locals all --clear
dotnet restore
dotnet outdated
dotnet add package Microsoft.AspNetCore.App --version 10.0.0
Alternatively, you can update dependencies manually in NuGet Package Manager within Visual Studio.
Step 4: Refactor Code to Align with .NET 10 Standards
After updating dependencies, it’s essential to check for deprecated APIs and rewrite code where necessary. .NET 10 introduces new features and optimizations, so updating your codebase will help you fully utilize its capabilities.
1. Identify and Replace Deprecated APIs
Use the .NET Upgrade Assistant to analyze your project for outdated APIs:
dotnet upgrade-assistant analyze.
This tool provides a report on deprecated methods and suggests alternative implementations.
Common Fixes in .NET 10:
- Update Identity APIs for authentication.
- Refactor Entity Framework Core Queries for compatibility.
- Use new ASP.NET Core middleware configurations.
2. Implement C# 14 Features for Better Code Efficiency
.NET 10 ships with C# 14, which introduces new language features for better code readability and maintainability.
C# 14 allows primary constructors in all types, reducing unnecessary boilerplate code.
Before (.NET 8 and older):
public class User
{
public string Name { get; }
public int Age { get; }
public User(string name, int age)
{
Name = name;
Age = age;
}
}
After (.NET 10 with C# 14):
public class User(string name, int age)
{
public string Name { get; } = name;
public int Age { get; } = age;
}
Use Collection Expressions for Cleaner Code
C# 14 makes initializing lists and dictionaries simpler:
Before:
var numbers = new List { 1, 2, 3, 4, 5 };
After (.NET 10 with C# 14):
var numbers = [1, 2, 3, 4, 5];
Step 5: Test and Debug the Upgraded Application
Once your project is updated, testing is crucial to ensure stability and detect potential issues.
1. Run Unit Tests
Use the following command to execute unit tests and verify functionality:
dotnet test. If any tests fail, update the affected code accordingly.
2. Performance Benchmarking
Dot Net 10 comes with improved performance optimizations, so running benchmarks can help you analyze speed improvements.
Install BenchmarkDotNet and run tests:
dotnet add package BenchmarkDotNet
Example Benchmark Code:
using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;
public class PerformanceTest
{
private List numbers = Enumerable.Range(1, 1000000).ToList();
[Benchmark]
public void TestSorting()
{
numbers.Sort();
}
}
BenchmarkRunner.Run();
This will compare performance before and after migration.
Step 6: Rebuild, Deploy, and Monitor
After testing, the final step is rebuilding and deploying the updated application.
1. Rebuild and Publish
Run the following command to create a production-ready build:
dotnet publish -c Release -o ./publish. This generates optimized binaries for deployment.
2. Deploy to Production Environment
Deploy your application to a web server, Azure, AWS, or a self-hosted environment.
For Dockerized Applications:
If your application is containerized, update the Dockerfile to use .NET 10:
FROM mcr.microsoft.com/dotnet/aspnet:10.0 AS base
WORKDIR /app
COPY . .
ENTRYPOINT ["dotnet", "YourApp.dll"]
Then rebuild and deploy:
docker build -t yourapp-dotnet10 .
docker run -d -p 5000:80 yourapp-dotnet10
