PowerTools crashes during visual studio launch time

[abhiranjankumar00]

FSharp PowerTools is crashing with following exception after last upgrade. Seems to be some issue with tasklist comment manager.

Below is the related component from ActivityLog.xml

Known workarounds

None.

Tried following

• Repairing
• devenv /setup
• devenv /clearcache -> devenv /updateconfiguration
• deleting %LOCALAPPDATA%\Microsoft\Visual Studion{version}\ComponentModelCache

Related information

• Operating system : Windows 7
• Extension version: 2.5.6.2340

@abhiranjankumar00 turn off task list comments on settings dialog.

This project is not actively maintained anymore, everything has been ported to Visual F# Tools and is available in VS 2017.

@smoothdeveloper may fix the bug, but frankly I don't see the point. Just use VS 2017.

[abhiranjankumar00]

Thanks.

Version 2.5.2 2.5.0 works for this config. Can't upgrade to 2017, on work system.

@vasily-kirichenko Many people are stuck on VS2013 and VS2015 for a long time to come (enterprises are often 2-5 years behind in VS editions). Can we do a patch release to turn off task list comments by default?

[smoothdeveloper]

@abhiranjankumar00 can you confirm disabling the setting @vasily-kirichenko points at is a valid workaround?

When I compile/run VFPT in DEBUG, I've seen error related to TODO comment extractor which I think is related to this component, but haven't seen the issue in RELEASE builds.

I'm still in process of completing update to latest FCS in #1496 but there are obscure test failures I haven't had chance to look at (beside the one related to Fantomas, which will be fixed with the new nuget package).

[abhiranjankumar00]

Nope, it's not working even after disabling task list. No release since 2.5.2 has been working for me. Had to switch to 2.5.0.

In later versions, there's no rename refactoring option, no code outlining and few more.
While generating references for F# interactive this exception is thrown:

Just use whatever version that works for you.

@abhiranjankumar00 thanks for the update, I'm seeing this is running on VS2013 while I was testing in 2015.

For example that last message seems to be an issue with conflicting FSharp.Core, because one older version is loaded in VS2013 process.

I think your best course of action is to try to build the stuff locally to try to troubleshoot to make it work in VS2013 (I can help you with that) or to find the last release which effectively supports VS2013 (which we will put in the readme).

Sure, I will try after somedays. Going on a vacation now.

to find the last release which effectively supports VS2013 (which we will put in the readme).

That's 2.5.0.
