Constructors

EfModelAnalyzer(ICompilationFactory, IFileSystem, IEntityFileDiscovery)

Infrastructure implementation for advanced Entity Framework model analysis using Roslyn and semantic models.

public EfModelAnalyzer(ICompilationFactory compilationFactory, IFileSystem fileSystem, IEntityFileDiscovery entityFileDiscovery)

Parameters

compilationFactory ICompilationFactory

The factory for creating Roslyn compilations.

fileSystem IFileSystem

The file system abstraction for reading source files.

entityFileDiscovery IEntityFileDiscovery

The service for discovering entity-related source files.

Methods

AnalyzeContextAsync(string, string?)

Analyzes an Entity Framework DbContext file to extract entity and relationship information.

public Task<EfModel> AnalyzeContextAsync(string path, string? contextName)

Parameters

path string

The file path to the DbContext class.

contextName string

Optional name of the specific context to analyze. If null, the first context found is used.

Returns

Task<EfModel>

A Task<TResult> that resolves to an EfModel containing entities and relationships.

Exceptions

AnalysisException

Thrown when DbContext is not found in the file or semantic symbol cannot be resolved.

public Task<EfModel> AnalyzeSnapshotAsync(string snapshotPath, string? snapshotName)

Parameters

snapshotPath string

The file path to the ModelSnapshot class.

snapshotName string

Optional name of the specific snapshot to analyze. If null, the first snapshot found is used.

Returns

Task<EfModel>

A Task<TResult> that resolves to an EfModel containing entities and relationships.

Exceptions
