Outer Build (Multi-Targeting Entry Point) + +When MSBuild encounters a project with `StrideGraphicsApiDependent=true` and multiple `TargetFrameworks`: + +```xml + + + net8.0;net8.0-android + true + + +``` + +MSBuild performs an **outer build** that: +1. Calls `_ComputeTargetFrameworkItems` target +2. For each framework, calls `_StrideQueryGraphicsApis` to get the API list +3. Creates inner builds for each `(Framework, API)` pair +4. Passes `TargetFramework` and `StrideGraphicsApi` to each inner build + +#### 2. Inner Build (Actual Compilation) + +Each inner build receives: +``` +TargetFramework=net8.0 +StrideGraphicsApi=Vulkan +``` + +The inner build then: +1. Sets `StrideGraphicsApiDefines` based on `StrideGraphicsApi` +2. Adds defines to `DefineConstants` +3. Sets output path to `bin\$(Configuration)\$(TargetFramework)\$(StrideGraphicsApi)\` +4. Compiles the code with API-specific defines + +#### 3. Design-Time Build (IntelliSense) + +Visual Studio and IDEs perform frequent **design-time builds** for IntelliSense. These are marked with `DesignTimeBuild=true`. + +For API-dependent projects, the design-time build needs to pick a single API. The priority order is: + +1. `StrideDefaultGraphicsApiDesignTime` (if set in `Stride.props`) +2. `StrideDefaultGraphicsApi` (first API in the list) + +**Developer Tip**: When working on Vulkan-specific code, uncomment this line in `sources/targets/Stride.props`: + +```xml + +Vulkan +``` + +This makes Visual Studio show Vulkan-specific code as active instead of graying it out. + +## Output Path Structure + +### API-Dependent Projects + +Projects with `StrideGraphicsApiDependent=true` organize outputs by API: + +``` +bin/ +└── Release/ + └── net8.0/ + ├── Direct3D11/ + │ ├── Stride.Graphics.dll + │ ├── Stride.Graphics.pdb + │ └── Stride.Graphics.xml + ├── Direct3D12/ + │ ├── Stride.Graphics.dll + │ └── ... + ├── Vulkan/ + │ ├── Stride.Graphics.dll + │ ├── libvulkan-1.dll (native) + │ └── ... + ├── OpenGL/ + │ └── ... + └── OpenGLES/ + └── ... + +obj/ +└── Release/ + └── net8.0/ + ├── Direct3D11/ + │ └── Stride.Graphics.dll + ├── Vulkan/ + │ └── Stride.Graphics.dll + └── ... +``` + +This is controlled by `Stride.targets`: + +```xml + + false + false + + obj\$(Configuration)\$(TargetFramework)\$(StrideGraphicsApi)\ + bin\$(Configuration)\$(TargetFramework)\$(StrideGraphicsApi)\ + +``` + +### API-Independent Projects + +Regular projects (without `StrideGraphicsApiDependent`) use standard .NET output paths: + +``` +bin/ +└── Release/ + └── net8.0/ + ├── MyGame.dll + └── MyGame.exe +``` + +## NuGet Package Structure + +### Runtime Library Packages + +Stride runtime packages (like `Stride.Graphics`) include all API variants: + +``` +Stride.Graphics.nupkg +└── lib/ + └── net8.0/ + ├── Stride.Graphics.dll (placeholder, smallest API) + ├── Stride.Graphics.xml (shared documentation) + ├── Direct3D11/ + │ └── Stride.Graphics.dll + ├── Direct3D12/ + │ └── Stride.Graphics.dll + ├── Vulkan/ + │ ├── Stride.Graphics.dll + │ └── (native Vulkan dependencies) + ├── OpenGL/ + │ └── Stride.Graphics.dll + └── OpenGLES/ + └── Stride.Graphics.dll +``` + +**Important**: The top-level `.dll` is a **placeholder** that allows NuGet to recognize the package as compatible with `net8.0`. The actual API-specific DLLs are in subfolders. + +### How Package Resolution Works + +When you reference `Stride.Graphics` in your game project, the build system uses special targets to resolve the correct API variant: + +#### For PackageReference (NuGet Packages) + +`Stride.GraphicsApi.PackageReference.targets` handles package resolution: + +```xml + + + + <_StrideGraphicsApiCurrent>$(StrideGraphicsApi) + <_StrideGraphicsApiCurrent Condition="'$(_StrideGraphicsApiCurrent)' == ''">$(StrideDefaultGraphicsApi) + + + + + <_StrideGraphicsRuntimeCopyLocalFodlers Include="@(RuntimeCopyLocalItems->'%(RootDir)%(Directory)$(_StrideGraphicsApiCurrent)')" + Condition="Exists('%(RootDir)%(Directory)$(_StrideGraphicsApiCurrent)')"> + + + + + + + + + + + + +``` + +**Flow**: +1. Checks `$(StrideGraphicsApi)` (e.g., `Vulkan`) +2. Looks for `lib/net8.0/Vulkan/` subfolder in package +3. Removes the placeholder `lib/net8.0/Stride.Graphics.dll` +4. Adds `lib/net8.0/Vulkan/Stride.Graphics.dll` to build output + +#### For ProjectReference (Development) + +When building from source, `Stride.GraphicsApi.Dev.targets` handles project-to-project references: + +```xml + + + + + + + + + <_MSBuildProjectReferenceExistent Condition="'%(_StrideGraphicsApiDependentItems.StrideGraphicsApiDependent)' == 'true'"> + $(_StrideGraphicsApiCurrent) + %(SetTargetFramework);StrideGraphicsApi=$(_StrideGraphicsApiCurrent) + + + +``` + +**Flow**: +1. For each ``, query if it has `StrideGraphicsApiDependent=true` +2. If yes, pass current `StrideGraphicsApi` to that project +3. If no, remove `StrideGraphicsApi` from build properties (avoid unnecessary rebuilds) + +### Reference Chain Example + +``` +MyGame.csproj (no API dependency) + └── References: Stride.Engine + ├── StrideGraphicsApiDependent=false + └── References: Stride.Graphics + ├── StrideGraphicsApiDependent=true + └── Built with API=$(StrideGraphicsApi from MyGame) +``` + +When building `MyGame` with `StrideGraphicsApi=Vulkan`: +1. `MyGame` builds normally (no API variant) +2. `Stride.Engine` receives `StrideGraphicsApi=Vulkan` but ignores it (not API-dependent) +3. `Stride.Graphics` receives `StrideGraphicsApi=Vulkan` and builds the Vulkan variant +4.

into property values +- Helpful for support/issues + +**Effort:** 1-2 days + +### 4.4 Build Performance Metrics + +**Problem:** Hard to identify slow parts of build. + +**Proposal:** Add timing targets: + +```xml + + + $([System.DateTime]::Now.Ticks) + + + + + + $([System.DateTime]::Now.Ticks) + $([System.TimeSpan]::FromTicks($([MSBuild]::Subtract($(StrideBuildEndTime), $(StrideBuildStartTime)))))) + + + +``` + +**Benefits:** +- Track build performance over time +- Identify regressions +- Optimize slow steps + +**Effort:** 2-3 days + +## Phase 5: Modern MSBuild Features + +### 5.1 Use Central Package Management + +**Problem:** Package versions scattered across many `.csproj` files. + +**Proposal:** Use `Directory.Packages.props`: + +```xml + + + + true + + + + + + + + +``` + +```xml + + + + +``` + +**Benefits:** +- ✅ Single source of truth for versions +- ✅ Easier updates +- ✅ Consistent across solution +- ✅ Standard .NET 8+ feature + +**Effort:** 2-3 weeks (migrate all projects) + +**Risk:** Low (.NET SDK feature) + +### 5.2 Use SDK-Style Project Files + +**Problem:** Some projects still use legacy `.csproj` format. + +**Example migration:** + +```xml + + + + + Debug + AnyCPU + + + + + + + + + + + + + + + + + + + + true + + + + +``` + +**Benefits:** +- Shorter, more readable +- Automatic globbing (no need to list every file) +- Better tooling support + +**Effort:** 3-4 weeks + +**Risk:** Low (well-established pattern) + +### 5.3 Use .NET 10 Features + +**Proposal:** Adopt .NET 10-specific MSBuild improvements: + +- **OutputItemType** for better NuGet pack control +- **SuppressTfmSupportBuildWarnings** to clean up warnings +- **EnableTrimAnalyzer** for ahead-of-time compilation readiness +- **IsTrimmable** for mobile optimization + +```xml + + + true + true + + + true + +``` + +**Benefits:** +- Modern .NET features +- Better mobile app size +- AOT compilation readiness + +**Effort:** 4-6 weeks (requires code changes for trimming) + +## Long-Term Vision + +### Complete Rewrite Using MSBuild SDK + +**Goal:** Create `Stride.Sdk` that encapsulates all build logic. + +**Usage (project file):** + +```xml +
