VSDiagnostics

This new release focused on bug fixes and maintenance rather than a slew of new features.

New features

Category	Name	Description
Async	VSD0041	A non-async, non-Task method should not end with -Async.
Strings	VSD0042	A string.Format() call lacks arguments and will cause a runtime exception

Bug fixes

• No more random NullReferenceException when certain analyzers are triggered that use the IsDefinedInAncestor helper
• Completely rewrote the "TryCast vs As/Not null" analyzer which makes it much more reliable in many different scenarios
• "Use explicit modifier" is no longer a message but instead works as a context action
• Changing a field to a property will no longer be suggested when the field is passed as ref or out inside that same class. If it is passed outside of it, it is still triggered and will introduce uncompilable code.
• Explicit interface implementations and partial methods no longer suggest an access modifier.
• Clarified message for the empty catch block analyzer.
• A rename IDE helper is added when conflicts due to renaming occur.
• No longer renaming when changing a field to a property.
• Using string.Empty now respects surrounding trivia.
• No more NullReferenceExceptions when using a doc comment that references Nullable{T}
• Naming conventions now handle different situations better, including SNAKE_UPPER_CASE
• No more NullReferenceException when defining an enum
• "OnPropertyChangedWithoutNameOf" now triggers on parenthesized expressions as well and triggers in partial classes too.
• Using an alias respects surrounding trivia.
• Improved VSD0036's message
• No longer trigger the string.Empty suggestion for case labels
• Improved 'Use alias' suggestions when affected by using statements

VSDiagnostics

Due to a small bundling issue of the NuGet release, v1.9.1-beta is the same as v1.9.0-beta but it should actually work this time.

VSDiagnostics

Finally, the next version of VSDiagnostics is here!

After two months of on-and-off work and a lot of collaboration help from @Hosch250, we can now distribute the next version of VSDiagnostics. This release contains a bunch of bug fixes and new features (obviously) and we also updated some dependencies like RoslynTester. This allowed us to more reliably test our diagnostics and as such reinforces our belief in solid workings. Nothing is bug-free however so we won't claim we are either. This release has been marked as pre-release to indicate that we would like further testing from you in a real-world scenario. Try out this new version and let us know if something behaves in a way you don't expect so we can fix that for the actual release!

Special thanks to @nemec as well for providing an analyzer.

VSDiagnostics

First stable release! Updated the dependencies to be in line with Visual Studio 2015's release and removed beta dependencies from NUnit.

VSDiagnostics

No new features in this release but several bugfixes and maintenance tasks instead. The full list of changes can be found here but in summary:

Bugfixes

• No more "empty string literal" warnings for attributes.
• Writing an incomplete method no longer crashes the analyzer.
• Improved SimplifyExpressionBodiedMember when it comes to trivia and attributes.
• private fields marked as constant or static now expect UpperCamelCase.

Tasks

• There are no longer dependencies on nightly builds: everything is based on RC2.
• Tests are now using RoslynTester v1.3.0 which means they are less verbose.
• Integrated build server in the releasing process.
• Renamed ArgumentExceptionWithNameofOperator to ArgumentExceptionWithoutNameofOperator.
• Cleaned up internal visibility.
