This documentation how to upgrade and move to current .NET 7 based NetDaemon runtime v3.x to .NET 8 based NetDaemon runtime 4. There are some breaking issues but should be quite straight forward upgrade your applications and runtime environment.

Development environment

info

We try to always keep NetDaemon up-to-date with the latest versions of .NET. Since we are a small team of maintainers we can not maintain more than one version at a time. This is why new features never is added to old versions. We recommend users to update their apps when ever a new major version of NetDaemon.

The following changes have to be executed in order to develop your apps for NetDaemon 4 and .NET 8.

1. Update nuget packages​

In this release we decided to change naming of NetDaemon nuget packages. The names are basically the same but without the JoySoftware. The reason is we needed to make sure we got the ownership of the NetDaemon id on our nuget packages for security reasons.

  1. In all .NET project files *.csproj, rename all nuget references that starts with JoySoftware.NetDaemon to NetDaemon. For users that uses the source deploy option you will have to add theNetDaemon.AppModel.SourceDeployedApps nuget package!
  2. Change the target framework to 8.0
  3. Update Microsoft .NET references in your C# files to the corresponding .NET 8 versions

2. Update docker containers and add-ons​

The docker container, change the name from netdaemon3 to netdaemon4. All other settings are the same.

If you are using the addon write down the current settings in your current 3.x based addon and install the version 4 version and update settings as needed. In version 4 the default path had changed from config/netdaemon3 to config/netdaemon4.

3. Update the code generator​

As some of the namespaces have changed you should update your locally installed version of the Code generator by running the following command:

dotnet tool install -g NetDaemon.HassModel.CodeGen
warning

You may need to uninstall the old code generator by using the dotnet tool uninstall -g JoySoftware.NetDaemon.HassModel.CodeGen command. Since we have changed the namespace there will be conflicting tool command names.

...and then re-run the generator to create an updated version of HomeAssistantGenerated.cs

4. Update the CLI tool​

As some of the namespaces have changed you should first uninstall the cli tool by dotnet new uninstall JoySoftware.NetDaemon.Templates.Project and then install the new too by

dotnet new --install NetDaemon.Templates.Project
