This page contains steps to build and run the .NET MAUI repository from source. If you are looking to build apps with .NET MAUI please head over to the .NET MAUI documentation to get started.
In most cases, when you have Visual Studio installed with the .NET workloads checked, these steps are not required.
- Install the latest .NET 6:
- Install the released 6.0.2xx SDK as well:
This is a known issue where we can't use rollback files from one SDK band in another. dotnet/sdk#23402
- Clear your nuget cache:
dotnet nuget locals all --clear
NOTE: this is going to contain the "stable" versions of the packages, so you will have to clear the NuGet cache when this feed changes and when .NET ships. The various
darc-pub-dotnet-*
feeds are temporary and are generated on various builds. These feeds my disappear and be replaced with new ones as new builds come out. Make sure to verify that you are on the latest here and clear the nuget cache if it changes. - If you're on a Windows development machine, install SDK 20348
- If you're on a MacOS development machine, install PowerShell
You'll probably need to run these commands with elevated privileges:
Install the .NET MAUI workload using the versions from a particular branch:
-
First, install .NET SDK 6.0.300
-
Next run the following workload command:
dotnet workload install maui `
--from-rollback-file https://aka.ms/dotnet/maui/6.0.300/rc.1.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/darc-pub-dotnet-runtime-323bf2dd/nuget/v3/index.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/darc-pub-dotnet-emsdk-572aeedc/nuget/v3/index.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json `
--source https://api.nuget.org/v3/index.json
-
First, install .NET SDK 6.0.300
-
Next run the following workload command:
dotnet workload install maui `
--from-rollback-file https://aka.ms/dotnet/maui/main.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/darc-pub-dotnet-runtime-bd261ea4/nuget/v3/index.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/darc-pub-dotnet-emsdk-52e9452f-3/nuget/v3/index.json `
--source https://pkgs.dev.azure.com/dnceng/public/_packaging/dotnet6/nuget/v3/index.json `
--source https://api.nuget.org/v3/index.json
Windows:
iwr https://aka.ms/dotnet/maui/maui-install.ps1 -OutFile maui-install.ps1;
.\maui-install.ps1 -b 'release/6.0.2xx-preview14' -v '6.0.200-preview'
MacOS:
curl -O -L https://aka.ms/dotnet/maui/maui-install.ps1
sudo pwsh -File ./maui-install.ps1 -b 'release/6.0.2xx-preview14' -v '6.0.200-preview'
NOTE: the branch (
-b 'release/6.0.2xx-preview14'
) and version (-v 6.0.200-preview
) parameters. The "preview 14" branch currently requires the 6.0.200 SDK band since the manifests are all in that SDK band - this will change in the future
iOS and MacCatalyst will require Xcode 13.3 Stable. You can get this here.
Android API-31 (Android 12) is now the default in .NET 6.
This will build and launch Visual Studio using global workloads
dotnet tool restore
dotnet cake --target=VS-NET6 --workloads=global
You can run a Cake
target to bootstrap .NET 6 in bin\dotnet
and launch Visual Studio:
dotnet tool restore
dotnet cake --target=VS-NET6
NOTES:
- If the IDE doesn't show any Android devices try unloading and reloading the
Sample.Droid-net6
project.
You can also run commands individually:
# install local tools required to build (cake, pwsh, etc..)
dotnet tool restore
# Provision .NET 6 in bin\dotnet
dotnet build src\DotNet\DotNet.csproj
# Builds Maui MSBuild tasks
.\bin\dotnet\dotnet build Microsoft.Maui.BuildTasks.sln
# Builds the rest of Maui
.\bin\dotnet\dotnet build Microsoft.Maui.sln
# (Windows-only) to launch Visual Studio
dotnet cake --target=VS-DOGFOOD
To build & run .NET 6 sample apps, you will also need to use .\bin\dotnet\dotnet
or just dotnet
if you've installed the workloads globally:
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.Droid\Maui.Controls.Sample.Droid.csproj -t:Run
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.iOS\Maui.Controls.Sample.iOS.csproj -t:Run
Try out a "single project", you will need the -f
switch to choose the platform:
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-android
.\bin\dotnet\dotnet build src\Controls\samples\Controls.Sample.SingleProject\Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-ios
💡 VS Mac is not yet supported.
# install local tools required to build (cake, pwsh, etc..)
dotnet tool restore
# build MAUI
dotnet build Microsoft.Maui-mac.slnf
Try out a "single project", you will need the -f
switch to choose the platform:
dotnet build src/Controls/samples/Controls.Sample.SingleProject/Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-ios
dotnet build src/Controls/samples/Controls.Sample.SingleProject/Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-maccatalyst
dotnet build src/Controls/samples/Controls.Sample.SingleProject/Maui.Controls.Sample.SingleProject.csproj -t:Run -f net6.0-android
To build and run Blazor Desktop samples, check out the Blazor Desktop wiki topic.
To build and run WinUI 3 support, please install the additional components mentioned on the Getting Started page and run:
dotnet tool restore
dotnet cake --target=VS-WINUI
To workaround a performance issue, all Resource.designer.cs
generation is disabled for class libraries in this repo.
If you need to add a new @(AndroidResource)
value to be used from C#
code in .NET MAUI:
-
Comment out the
<PropertyGroup>
inDirectory.Build.targets
that sets$(AndroidGenerateResourceDesigner)
and$(AndroidUseIntermediateDesignerFile)
tofalse
. -
Build .NET MAUI as you normally would. You will get compiler errors about duplicate fields, but
obj\Debug\net6.0-android\Resource.designer.cs
should now be generated. -
Open
obj\Debug\net6.0-android\Resource.designer.cs
, and find the field you need such as:
// aapt resource value: 0x7F010000
public static int foo = 2130771968;
-
Copy this field to the
Resource.designer.cs
checked into source control, such as:src\Controls\src\Core\Platform\Android\Resource.designer.cs
-
Restore the commented code in
Directory.Build.targets
.
