11/15/2015 Nova CodeDOM v6.4, Nova Studio v2.3

  • Fixed an issue with the caching of extension methods added in the last release that could cause resolve errors.

11/1/2015 Nova CodeDOM v6.3, Nova Studio v2.3

  • Possible BREAKING change: Split new NamedObjectDictionary/NamedObjectGroup out from existing NamedCodeObjectDictionary/NamedCodeObjectGroup classes - the first can hold metadata (IMemberDefinition/MemberInfo) objects, while the second is now restricted to INamedCodeObjects. Client code making use of NamedCodeObjectGroup should be changed to use NamedObjectGroup instead if compile errors occur. This change was made to support part of the implementation of the caching of extension method lookups for better performance (see below).

  • Fixed a resolving problem involving delegate fields in base classes with inferred type arguments.

  • Added support for InternalsVisibleTo assembly attributes that require resolving of the entire containing code unit in order to evaluate the string constant parameter (due to references to constant strings declared later in the file).

  • Performance: Removed all uses of HasFlag() for up to 10% better performance.

  • Performance: Added caching of extension method lookups on namespaces for up to 33% better performance on very large projects with heavy use of extension methods (minor or insignificant difference on smaller projects or with little extension method use).

  • Performance: Added caching of other parts of partial types for a significant performance improvement when there are a lot of partial types. The cached lists of other parts are reset for all parts when any TypeDecl is added/removed to/from a parent NamespaceDecl or TypeDecl.

  • Performance: Improved handling of messages by Solution and CodeUnit, for much better performance on projects with very large numbers of messages (such as errors).

  • UI Performance: Improved performance of very large numbers of messages (such as errors) in the UI.

10/3/2015 Nova CodeDOM v6.2, Nova Studio v2.1

  • Added support for implicit conversion of Literal interpolated strings to parameters of type IFormattable (C# 6.0).

  • Fixed line/col info for expression objects parsed from interpolated strings.

  • Added UI support in Nova Studio for expression objects parsed from interpolated strings.

  • Added Index.FindTypeArgument() to allow IndexerRef.EvaluateType() to revert to the default behavior of evaluating any type arguments without causing any recursion problems.

3/22/2015 Nova CodeDOM v5.53, Nova Studio v1.53
