Typescript: Loss of Syntax Highlighting & TS Project Settings after install of VS2015 TS1.8.6

[rankida]

I chose to upgrade Typescript today. I uninstalled TS1.7.X and installed the latest VS2015 Tools for TS 1.8.6.

Since then I have lost syntax highlighting in visual studio and when I look at the properties of a project I get an error:

I suspect the issue was with the uninstall of the previous version rather than the install of 1.8.6.

Any ideas how I get the missing resources and syntax highlighting back?

@rankida can you share the install logs? %temp%\dd_TypeScript*?

also does repairing the TS1.8 installer fix the issue?

[rankida]

@mhegazy sadly a repair of TS1.8 has not fixed it. Nor has a reinstall of TS1.7.

All my install logs are attached. Sorry for the large dump of files.

[mhegazy]

what version of VS do you have installed?

[mhegazy]

From the logs, looks like you installed 1.8.4 on 2016-02-23, was that when it stooped working? or were there issues before that?

[rankida]

Sorry I should have added that info to the original post. I am running VS2015 Community Update 1

Microsoft Visual Studio Community 2015
Version 14.0.24720.00 Update 1
Microsoft .NET Framework
Version 4.6.01038

Installed Version: Community
...
TypeScript   1.8.6.0
TypeScript tools for Visual Studio

My current issues started today (around 3 hours ago) when I uninstalled TS1.7 and installed TS1.8, but I am also the originator of issue #7210. To resolve #7210 I ended up uninstalling the previous version of TS1.8 and re-installing TS1.7. With the new release of 1.8 I thought I would give it a go today, but it has not gone smoothly.

Looking at other issues I see #7445 which relates to failed builds due to the COMPUTE_PATHS. I also got this after my uninstall/reinstall but a restore of TS fixed it.

looks like multiple issues here.. the net result is an inconsistent state..
i need to know where to start looking.. here is what i see:

When was it working last? and what is happening now? can you edit files? can you build? what is the version of C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.8\tsc.exe, C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\TypeScript\TypeScript.Tasks.dll, and C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TypeScript\Microsoft.VisualStudio.LanguageServices.TypeScript.dll?

[rankida]

Sorry for the mess. Once I broke things I tried very hard to try and fix it.

I have been using TypeScript 1.7.6 successfully for a number of weeks. I started the upgrade to 1.8.6 at 2016-03-15 14:05:34 but Visual Studio was still running so I cancelled the install. I then thought I should uninstall the previous version, so you see the uninstall of 1.7.6 at 2016-03-15 14:15:11 and then proceeded to install the upgrade at 2016-03-15 14:18:41.

Having completed the above I was left with a system that was unable to build (COMPILE PATHS issue), errored in the project settings (as posted originally), syntax highlighting was lost, and compile on save did nothing. I then proceeded to perform 2016-03-15 14:28:21 repair 1.8.6 and 2016-03-15 14:32:18 instal 1.7.6 after which I was able to build the typescript from a project build, but the projects settings, syntax highlighting and compile on save still did not work. I have not managed to improve on this situation, though you can see I did try other installs/repairs with no success.

I am considering, though have not yet done, a repair of visual studio to see if that would fix it.

As for versions of files:

• C:\Program Files (x86)\Microsoft SDKsTypeScript\1.8\tsc.exe
  
• C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0TypeScriptTypeScript.Tasks.dll
  
• C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\MicrosoftTypeScript\Microsoft.VisualStudio.LanguageServices.TypeScript.dll

Can you try deleting: %localappdata%\Microsoft\VisualStudio\14.0\ComponentModelCache, running devenv /setup from the Developer Command Prompt for VS2015 (as an admin), and starting VS.

[rankida]

@paulvanbrenk Thanks!! That worked! I deleted ComponentModelCache and ran devenv /setup as admin and now I have syntax highlighting, compile on save and can view the TS settings in a project's properties. A few of my colleagues have also experienced similar issues (they ended up performing a system restore) so I will share the solution with them.

I have uploaded the copy of ComponentModelCache that I removed, if it is helpful. Ideally an uninstall/reinstall of TypeScript shouldn't corrupt Visual Studio, but I am just happy with the fix.

Thanks again!

Encountered the same issue with VS2015 update 3 and TypeScript Tools for VS 2015 2.0.6. Same fix worked, thanks!

[ilcorvo]

That didn't worked for me!!
What else can I do?

[stasku]

@paulvanbrenk , thank you. This worked for me on VS 2015 and TS 2.3.1.0

[birjitningomba]

Issue: Loss of Syntax Highlighting, Loss of ability to comment or uncomment code in visual studio for typescript files, unable to perform Ctrl + K and Ctrl + D
In my case the TS version is Version 2.1.4. and VS 2015 Update 3, Installing and uninstalling TS does not work.
I find the whole folder C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\MicrosoftTypeScript had only one file, TypeScriptTemplateRegistration.pkgdef
Also TypeScriptSourceMapReader.dll was missing from C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies

Solution:

1. I take from a friend the contents of the folder C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\MicrosoftTypeScript and paste it in mine.
2. I also copy the file, TypeScriptSourceMapReader.dll(_from a friend_) at from C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies
3. I go to C:\Users\10251338\AppData\Local\Microsoft\VisualStudio\14.0ComponentModelCache and delete all files
4. I go to command prompt(as admin), navigate to C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE> and run devenv /setup
5. Start Visual Studio and everything magically works.

@paulvanbrenk thanks a lot. Your fix also worked for me too. I had installed TS 2.2.1.0 on VS 2015 but the syntax highlighting wasn't working.

[Ashwin09GitHub]

@paulvanbrenk thanks a lot. it's working for me, I have VS 2015 Update 3. and TS 1.8

[shadyyehia]

Thanks it works for me too as a charm:)

[shibin4m]

@paulvanbrenk thanks a lot. Your fix also worked for me too. I had installed TS 2.4.1.0 for vs 2015 on VS 2015 update 3.

:)

[noxborough]

@paulvanbrenk Thanks!

FWIW... I just had to delete the ComponentModelCache directory and then start Visual Studio 2015 and it worked. (didn't need to run devenv /setup)

[DJ-Icebear]

I have this issue on VS2017, and the above fix doesn't work :'(
