Migrate from ASP.NET Core in .NET 8 to ASP.NET Core in .NET 9
This article explains how to update an ASP.NET Core in .NET 8 to ASP.NET Core in .NET 9.
Prerequisites
Visual Studio 2022 Preview with the ASP.NET and web development workload.
Update the .NET SDK version in global.json
If you rely on a global.json
file to target a specific .NET Core SDK version, update the version
property to the .NET 9.0 SDK version that's installed. For example:
{
"sdk": {
- "version": "8.0.100"
+ "version": "9.0.100"
}
}
Update the target framework
Update the project file's Target Framework Moniker (TFM) to net9.0
:
<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
- <TargetFramework>net8.0</TargetFramework>
+ <TargetFramework>net9.0</TargetFramework>
</PropertyGroup>
</Project>
Update package references
In the project file, update each Microsoft.AspNetCore.*
, Microsoft.EntityFrameworkCore.*
, Microsoft.Extensions.*
, and System.Net.Http.Json
package reference's Version
attribute to 9.0.0 or later. For example:
<ItemGroup>
- <PackageReference Include="Microsoft.AspNetCore.JsonPatch" Version="8.0.2" />
- <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="8.0.2" />
- <PackageReference Include="Microsoft.Extensions.Caching.Abstractions" Version="8.0.0" />
- <PackageReference Include="System.Net.Http.Json" Version="8.0.0" />
+ <PackageReference Include="Microsoft.AspNetCore.JsonPatch" Version="9.0.0-preview.1.24081.5" />
+ <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="9.0.0-preview.1.24081.2" />
+ <PackageReference Include="Microsoft.Extensions.Caching.Abstractions" Version="9.0.0-preview.1.24080.9" />
+ <PackageReference Include="System.Net.Http.Json" Version="9.0.0-preview.1.24080.9" />
</ItemGroup>
