…st-processed operation from original action. This results in another PostProcess being called on the codeaction. If postprocess was overriden in originalaction that'll be ignored the second time

Is it possible to have any sort of test for this? It seems really easy for this sort of thing to regress with all the virutal-members+crazy-inheritance that goes on in that type. |

I tried to get a test added, but there's nothing that appears to cover the types involved. |

* Remove duplicate lock DocumentState.s_syntaxTreeToIdMapLock This lock is only being used to protect access to an instance which contains internal synchronization. * Better handle surrounding directives when inlining a local variable. * Add tests. * Share code between VB and C#. * Reduce allocations in UnboundLambda Fixes #23463 * Restore ReturnInferenceCacheKey as the key for _returnInferenceCache * Update code to more closely follow patterns of the original code * Cleanup from code review * basic fix for intellisense in Immediate window * better comments and cleanup * Add basic integration tests * cleanup inproc Immediate window integration test helper * fix incorrect comment * address PR feedback * create Immediate window on ImmediateWindow_InProc.GetText() * Verify MSBuild version in Developer CMD prompt Roslyn is designed to have the simplest possible contribution story: clone then build. Every pre-req needed is either located on the machine or bootstrapped via NuGet. All the way down to using an xcopy MSBuild if needed. The one case which causes a problem is the VS command prompt. In this case MSBuild is pre-installed on the machine and may or may not be suitable for building Roslyn. Previously when building from a VS command prompt we just used whatever MSBuild was provided. The assumption being a developer command prompt was an explicit statement of whath MSBuild you wanted to use. Based on all of our customer reports though this does not seem to be the assumption that consumers of our repo have. The build gave them no explicit errors about the provided toolset and hence when the build failed they assigned flakiness to our repo. Going forward we are applying the same version validation to MSBuild when provided via a developer command prompt. If it doesn't match we will refuse to build asking the user to upgrade VS or build from a normal command prompt. * Remove unneeded debugging line * Comment about pre-release * Added minimum version * Add Omit If Default style option * Add space to be like test without the omit * Add/Remove without needing a property * Reformat * PR feedback * Fix VB diagnostic based on feedback * Handle case of NotApplicable modifier and field declaration list * Fix tests * PR feedback * PR feedback * PreviewCodeAction was overriding ComputeOperations but returning a post-processed operation from original action.

(#24512) * put listener change back in (#24120) * leave old types in legacy folder until partner teams move to new interface * added legacy waiter to support partner teams * Remove methods indirecting access to _metadataFileNameToConvertedProjectReference This field is documented as being written and read from any thread, but in practice all uses are guarded by an AssertIsForeground(). Thus we can get rid of the helper methods that are trying to "help" by locking before accessing the fields, making it really hard to track all the real uses of it. * Make method static that doesn't need state * add a comment to address PR feedback * Fix up tests of P2P to metadata reference conversion It turns out we had some tests, but the tests were disabled. This was because the tests weren't working properly anyways: they were calling into UpdateProjectBinPath which only updated some (but not all) of the project state. That was an internal helper method that shouldn't be used by tests. Updating the tests to use SetBinOutputPathAndRelatedData works better. * Delete debug-only reference validation This was some legacy code that tried to verify that the references we have from the project system match up to what DTE and other sources say. This was debug-only, and the actual asserts were commented out. This is deadweight at this point, so delete it. * added and cleaned up logs around build and live diagnostics. (#24551) also added RoslynActivityLogger that can be enabled through project-system-tool * Avoid closure allocations on the BindSyntaxTreeToId fast path * CS1628 error text mentions in parameters; fixes #24584 * Small cleanup of completion logic. * Move to xunit.console for CoreClr tests Previously we were using xunit.console for desktop tests and dotnet-xunit for our CoreClr tests. This change unifies us on top of xunit.console (now that it has a netcoreapp2.0 version available). * Move unix builds to xunit.runner.console as well * Get actual directory name, not file * Fix dir name issue * fixed build break

PreviewCodeAction was overriding ComputeOperations but returning a post-processed operation from the original action. This results in another PostProcess being called on the codeaction. If postprocess was overriden in originalaction that'll be ignored the second time
Customer scenario
Bring up the a lightbulb for a codeaction that has the postprocess method overridden. Click on the Preview Changes button to bring up the preview dialog and then apply the codeaction. This can lead to the codeaction crashing and being disabled.

Workarounds, if any
Also, why we think they are insufficient for RC vs. RC2, RC3, or RTW
Risk
This is generally a measure our how central the affected code is to adjacent
scenarios and thus how likely your fix is to destabilize a broader area of code
Performance impact
(with a brief justification for that assessment (e.g. "Low perf impact because no extra allocations/no complexity changes" vs. "Low")
Is this a regression from a previous update?
Root cause analysis
How did we miss it? What tests are we adding to guard against it in the future?
How was the bug found?
(E.g. customer reported it vs. ad hoc testing)
Test documentation updated?
If this is a new non-compiler feature or a significant improvement to an existing feature, update https://github.com/dotnet/roslyn/wiki/Manual-Testing once you know which release it is targeting.
