Check targetMetadata before reading file metadata. As written, every JSON/XML/YAML document is interpreted as having reserved schema fields even when T has no generated or legacy schema metadata, so an ordinary unversioned model with a business property such as string Version or int Version = 0 now throws FormatException before reaching the direct-load branch. These configurations previously deserialized normally and should not be subjected to schema validation.

Route metadata reads through the same recovery behavior as the actual configuration load. For a versioned model using CommonFileProvider, malformed primary JSON/XML/YAML makes ReadSchemaMetadata throw here before FormatProviderBase.LoadConfiguration is entered, so its exception handler never restores the latest valid backup. This disables the advertised corruption recovery precisely when a versioned configuration needs it.

Restrict this scan to attributes that actually rename serialized members. Currently every string-valued constructor argument is treated as a serialized name, so a harmless annotation such as [DefaultValue("Version")] on a differently named property produces the error-level CWWR006 diagnostic even though none of the serializers names that property Version, unnecessarily blocking the consumer's build.

Generate global::System.NotImplementedException or add the corresponding using directive. In projects with implicit usings disabled, applying this code fix to a file that does not already import System inserts an unresolved NotImplementedException, so the offered fix leaves the project uncompilable; the current code-fix test also uses such a source file but only reruns generator diagnostics rather than compiling the result.

Line 21 adds an abstract member to the public IWritableFileProvider interface. Every consumer-defined provider will fail to compile after an upgrade, even when it does not use migrations. Move backup support to an optional capability interface, or release this as a documented major-version breaking change.

Fully qualify NotImplementedException.
The generated method body uses the unqualified name. If the target file has no using System; and the project disables implicit usings, the fixed document does not compile. The fix adds a using directive for the previous namespace only. Use global::System.NotImplementedException so the result compiles in every file.

IIncrementalGenerator ForAttributeWithMetadataName avoid CompilationProvider RegisterSourceOutput performance
💡 Result:
To optimize incremental source generators and avoid performance issues in.NET, you should leverage ForAttributeWithMetadataName, minimize dependencies on the CompilationProvider, and correctly choose between RegisterSourceOutput and RegisterImplementationSourceOutput. ForAttributeWithMetadataName (FAWMN) FAWMN is the recommended approach for generators that need to inspect syntax or symbols based on attributes [1][2]. It is significantly more efficient than CreateSyntaxProvider—often 99x faster—because it utilizes a specialized, low-overhead index to filter syntax nodes, avoiding costly semantic analysis or syntax node realization for irrelevant code [1][2][3]. Avoiding CompilationProvider Performance Pitfalls Combining your generator's pipeline with the CompilationProvider is a common performance anti-pattern [4][5][6]. The CompilationProvider updates frequently (e.g., on almost every keystroke in an IDE), which triggers the entire downstream pipeline to re-run [4][6]. - Do not combine your pipeline with the CompilationProvider unless absolutely necessary [4][5]. - If you need specific compilation-dependent information (such as assembly names), use Select to extract only that specific value into a separate provider, rather than combining with the entire compilation [4][5]. - Ensure your transformation steps return simple, value-equatable objects (e.g., tuples, records, or types with custom equality comparers) [2][7]. Never store SyntaxNode or ISymbol instances in your models, as they are not value-equatable and will break incrementality [2][8][7]. RegisterSourceOutput vs. RegisterImplementationSourceOutput - RegisterSourceOutput: Use this when the generated code provides symbols, APIs, or metadata that you intend to be directly visible and usable by the developer within the IDE (e.g., new methods or properties on existing partial classes) [9]. - RegisterImplementationSourceOutput: Use this for code that does not impact the semantic understanding of user code in the IDE (e.g., mapping logic, internal helpers, or code only accessed via reflection) [8][9]. This method signals to the IDE that the generation can be deferred or optimized, potentially saving significant resources during interactive editing [8][9][10]. By keeping your pipeline focused on small, immutable, and equatable models—and by avoiding the frequent triggers caused by the CompilationProvider—you ensure that your generator only performs heavy work when actual, relevant changes occur [2][11][8].

Use an incremental, attribute-filtered pipeline instead of CompilationProvider.
RegisterSourceOutput consumes context.CompilationProvider, so each compilation change invokes Execute. CollectModels then recursively visits every type in the source assembly and every referenced assembly and calls GetAttributes() on each type. This can make IDE edits perform a full reference-graph scan. Use ForAttributeWithMetadataName for source models and restrict any cross-assembly lookup to relevant assemblies.

When an externally edited YAML file contains a numeric non-integer or Boolean schema value such as Version: 1.5 or Version: true, Convert.ToInt32 rounds/converts it instead of rejecting it. The resulting integer can select an unrelated migration or make the loader deserialize the document directly as the wrong schema, whereas the JSON and XML readers correctly require integer syntax. Validate the deserialized value's integral numeric type/value before converting it.

When the preceding model is nested, this derives its namespace by truncating the fully qualified name at the final dot, so global::Example.Container.SettingsV1 produces Example.Container even though Container is a type. The CWWR011 code fix then inserts using Example.Container; and shortens the parameter to SettingsV1, leaving the document uncompilable. Retain the fully qualified type name or carry the actual containing namespace from the symbol.

For a JSON options model containing [JsonIgnore] public string Version { get; set; }, this loop still treats the CLR member name as serialized and emits the error-level CWWR006 diagnostic, even though the configured serializer never writes that property. This rejects valid models and contradicts the diagnostic's stated serialized-name condition; ignore annotations for the supported serializers need to be considered before reporting the collision.

Keep an overridable hook in the normal save path instead of calling the new private helper directly. Existing CommonFileProvider subclasses can override the previously protected GenerateBackupFile to customize backup storage; after this change those binaries may fail to load and recompiled subclasses cannot override it. Overriding the new virtual TryBackup does not restore the behavior because SaveToFileAsync bypasses that method, so ordinary saves silently use the built-in filesystem backup implementation.

Do not suppress collision checking for every JsonIgnoreAttribute. Unlike the earlier unconditional-ignore case, a member such as [JsonIgnore(Condition = JsonIgnoreCondition.WhenWritingDefault)] public int Version { get; set; } is fresh evidence that the blanket check is unsafe: whenever the value is nondefault, JSON serialization writes that business Version after the injected schema Version, and the metadata reader can interpret the later value as the schema version, causing a file saved by the library to select the wrong migration or be rejected as newer. Only an unconditional ignore should skip this diagnostic.

Honor JsonSerializerOptions.PropertyNameCaseInsensitive when locating metadata. With that option enabled and no naming policy, the model deserializer accepts fields such as version or MODELID, but this lookup checks only the exact reserved name and one naming-policy conversion. A versioned file using another casing therefore defaults to version 1 and can run the wrong migration, while a differently cased model ID bypasses the mismatch guard; the equivalent lookup in JsonAotFormatProvider has the same defect.

When a watched configuration file is replaced with a valid document for another model ID, this InvalidOperationException escapes OptionsMonitorImpl.ReloadAndNotify, which only handles I/O, JSON, and format exceptions. Because the reload runs from a timer callback, the application can terminate instead of retaining the last valid value as the reload path intends; either classify this as a handled format error or explicitly catch the mismatch during reload.

When JsonSerializerOptions.UnmappedMemberHandling or [JsonUnmappedMemberHandling] is set to Disallow, the injected Version (and ModelId) properties are unknown to the options model because the generated metadata members are explicit interface implementations. Consequently, a versioned document written here cannot be loaded again by either JSON provider: metadata parsing succeeds, but the subsequent model deserialization throws for the unmapped fields. Remove the reserved properties before binding or otherwise make the deserializer recognize them.

For a model with [JsonExtensionData], loading a generated configuration captures the injected ModelId and Version as extension data because they are not model properties. This loop writes those captured keys after the authoritative metadata; after a migration that preserves the extension dictionary, the stale old Version becomes the last duplicate and JsonElement.TryGetProperty reads it on the next load, causing the migration to run again or select the wrong schema. Skip reserved metadata keys while copying the serialized object.

Fresh evidence in the revised conditional-ignore handling is that JsonIgnoreCondition.Never has underlying value 0, yet this predicate classifies value 0 as always ignored (while explicit Always is not). Thus [JsonIgnore(Condition = JsonIgnoreCondition.Never)] public int Version ... bypasses CWWR006 even though JSON always emits that business property after the injected schema version, allowing it to override migration metadata; check specifically for Always instead.
