API Breaking Changes

Version 1.1.0

Removed VisualBasicCommandLineParser.ctor

During a toolset update we noticed the constructor on VisualBasicCommandLineParser was public. This in turn made many of the protected members of CommandLineParser a part of the API surface as it gave external customers an inheritance path.

It was never the intent for these members to be a part of the supported API surface. Creation of the parsers is meant to be done via the Default singleton properties. There seems to be little risk that we broke any customers here and hence we decided to remove this API.

PR: dotnet/roslyn#4169

Changed Simplifier methods to throw ArgumentNullExceptions

Changed Simplifier.ReduceAsync, Simplifier.ExpandAsync, and Simplifier.Expand methods to throw ArgumentNullExceptions if any non-optional, nullable arguments are passed in. Previously the user would get a NullReferenceException for synchronous methods and an AggregateException containing a NullReferenceException for asynchronous methods.

PR: dotnet/roslyn#5144

Version 1.3.0

Treat a method marked with both public and private flags as private

The scenario is loading an assembly where some methods, fields or nested types have accessibility flags set to 7 (all three bits set), which mean public AND private. After the fix, such flags are loaded to mean private. The compat change is we’re trading a compile-time success and runtime failure (native compiler) against a compile-time error (restoring the behavior of v1.2).

Details below:

• The native compiler successfully compiles the method and field case (those only yield runtime error System.TypeLoadException: Invalid Field Access Flags) and reported an accessibility error on the nested type.
• The 1.2 compiler generated errors:

error BC30390: 'C.Private Overloads Sub M()' is not accessible in this context because it is 'Private'.
error BC30389: 'C.F' is not accessible in this context because it is 'Private'.
error BC30389: 'C.C2' is not accessible in this context because it is 'Protected Friend'.
error BC30390: 'C2.Private Overloads Sub M2()' is not accessible in this context because it is 'Private'.

• The 1.3 compiler crashes.
• After fix, the same errors as 1.2 are generated again.

PR: dotnet/roslyn#11547

Don't emit bad DateTimeConstant, and load bad BadTimeConstant as default value instead

The change affects compatibility in two ways:

• When loading an invalid DateTimeConstant(-1), the compiler will use default(DateTime) instead, whereas the native compiler would produce code that fails to execute.
• DateTimeConstant(-1) will still count when we check that you don’t specify two default values. The compiler will produce an error, instead of succeeding (and producing IL with two attributes).
