Can't edit files in Visual Studio after installing 1.8.4 On Update 2 CTP

[OSUblake]

TypeScript Version:
1.8.4

Visual Studio Version:
Community 2015 CTP 14.0.25008.00

Everything was working fine using TypeScript 1.8.1 beta. After installing 1.8.4 last night, the editor no longer works. Typing does nothing. The onlys keys it responds to are enter, delete, backspace. The three drop-down lists at the top of the editor that let you jump to certain parts of your code are all blank.

I've tried all of the following with no luck.

• Repair/uninstall Visual Studio and TypeScript
• Disable extensions
• Uninstall ReSharper
• Clear MEF component cache
• Update devenv.exe.config

I also can't seem to stop Visual Studio from updating to the CTP when I reinstall. I started getting a lot of JavaScript language service crashes after installing the CTP. Viewing a compiled TS file would cause JavaScript to stop working.

I have the same problem. My co worker does not and the only major difference is I have the vs2015.2 CTP and he just has vs2015.1 rtm. Hope that helps

I ran into the same problem as well.

I was playing using the newly added ability to add comments to the tsconfig.json file. If I added a comment at the very top of the file, then this behavior occurred after a restart of VS.

To resolve, remove any comments at the top of the tsconfig.json file (only use inline comments to the json), and then restart VS. To be safe, you might try removing any comments to the file and restarting VS and see if that fixes it.

Update 2 CTP does not support TS 1.8.4. We are looking into why the setup did not show the correct blocking message.
TS has dependency on internal APIs that changed in Update 2, trying to install TS 1.8.4 (targeting Update1) will cause the language service to be broken.
Update 2 CTP has TS 1.8.1-beta in box, the next public release of Update2 should have the TS 1.8.4. sorry for the inconvenience.

@mhegazy - thanks for the update. Partly our fault for running a CTP :) The perf improvements have been worth it though.

If you've got some hacky way of rolling back to the 1.8.1-beta that'd be splendid.

uninstall TS 1.8.4, repair Update 2 entry in Add/Remove programs should do the trick.

Despite having Update 2 CTP installed, my Add/remove programs just shows
Microsoft Visual Studio Enterprise 2015 with Update 1

But CTP for update 2 was definitely installed and indeed when I run VS 2015 it says it's CTP for update 2

I guess the incorrect info being reported in add/remove programs is the reason why installation of TypeScript 1.8.4 wasn't blocked.

So I've uninstalled TS 1.8.4 - it was really quick and then repaired the only VS2015 entry (update 1) in add/remove programs so I no longer get those crashes in VS pointing me to the activity log but I also get a read-only TypeScript editing experience.

Sorry for so many words - I wanted to be specific and anticipate what you might suggest :) My other thread has the things I've tried already with regards to uninstall, reinstall, repair, etc.

I went to my layout folder for the update 2 CTP and found the pair of Typescript *.msi files. They wouldn't install as a newer version of the product was already present. Removing TypeScript 1.7.x and 1.8.x from add/remove programs still didn't let the *.msi files executes.

So I then fired up Windows Installer Cleanup Utility. It lists many packages for CTP update 2 - so that's good. It also still listed the TypeScript packages. I nuked them and then ran the ones from the update 2 ctp folder.

That got me back to VS 2015 throwing errors directing me to the activity log upon opening a TypeScript file.

I visited add/remove programs and removed TypeScript from there. Opening VS 2015 got me back to the behaviour described in this thread where I get the read-only TypeScript experience (but no errors raised in the GUI). Strange that even after uninstalling TypeScript I still got syntax highlighting, etc.

I'm now running a full repair from the VS 2015 Update 2 CTP installer. Fingers crossed.

🙅
Reboot after repair and it's still read-only. I noticed however that I can cut & paste code to the editor. Saving doesn't recompile the JS files though.

I'm heading home (GMT + 10 here) and will check this thread again in an hour or two. I have some work to do tonight so am very happy to be a guinea pig for any suggested fixes you may have.
