ReferenceConfiguration¶

Configure metadata references for test compilations. Call once via [ModuleInitializer] to make your project's types available in test source code.

Setup¶

internal static class TestInit
{
    [ModuleInitializer]
    public static void Init() =>
        ReferenceConfiguration.AddReferencesFromTypes(
            typeof(AutoNotifyAttribute),
            typeof(MyModel));
}

This ensures that when SymbolsFor(source), AnalyzeWith<T>(source), etc. compile the source string, they can resolve your attribute types and other dependencies.

Methods¶

Method	Description
`AddReferencesFromTypes(params Type[] types)`	Add references from types' containing assemblies
`AddReferences(params Assembly[] assemblies)`	Add references from assemblies directly
`AddReferences(params MetadataReference[] references)`	Add pre-built metadata references
`AddReferencesFromPaths(params string[] assemblyPaths)`	Add references from file paths
`Clear()`	Remove all configured references

When to Use¶

You need ReferenceConfiguration when your test source code references types from your own packages:

// This source references [AutoNotify] — needs the assembly reference
const string source = """
    [AutoNotify]
    public partial class Customer { }
    """;

await AnalyzeWith<MustBePartialAnalyzer>(source)
    .ShouldReportDiagnostic("RK1002");

Without configuration, the compilation would fail to resolve AutoNotifyAttribute.

What's Included by Default¶

RoslynTestBase automatically includes references to:

.NET base class libraries (System, System.Collections, etc.)
Microsoft.CodeAnalysis assemblies
Deepstaging.Roslyn core library

You only need to add references for your own assemblies.
