The tsc -v command run technically reads the TypeScript compiler version within the SDK directory set within the Windows Path variable  This doesn t necessarily reflect the latest version installed as the Path variable is not updated with subsequent installations   The version that VS NET uses to compile the TypeScript is what s in the project s configuration    lt TypeScriptToolsVersion gt 1 5 lt  TypeScriptToolsVersion gt   To help explain this more in detail I created the following post which has the specifics on the TypeScript versions installed  and which version VS NET uses to compile the TypeScript files   Which Version of TypeScript is Installed and Which Version is Visual Studio Using   I also added a feature request on Microsoft Connect to make viewing and switching the TypeScript targeted version in VS NET easier  This isn t really a TypeScript feature request as much as it is a VS NET IDE enhancement   Allow switching TypeScript configured version from Project Properties IDE

Based in the response of basarat  I give here a little more information how to run this in Visual Studio 2013    Go to Windows Start button -  All Programs -  Visual Studio 2013 -  Visual Studio Tools A windows is open with a list of tool       Select Developer Command Prompt for VS2013  In the opened Console write  tsc -v  You get the version  See Image      UPDATE   If you update your Visual Studio to a new version of Typescript as 1 0 x you don t see the last version here  To see the last version    Go to  C  Program Files  x86  Microsoft SDKs TypeScript  there you see directories of type 0 9  1 0 1 1 Enter the high number that you have  in this case 1 1  Copy the directory and run in CMD the command tsc -v  you get the version      NOTE  Typescript 1 3 install in directory 1 1  for that it is important to run the command to know the last version that you have installed   NOTE  It is possible that you have installed a version 1 3 and your code use 1 0 3  To avoid this if you have your Typescript in a separate s  project s  unload the project and see if the Typescript tag      lt TypeScriptToolsVersion gt 1 1 lt  TypeScriptToolsVersion gt     is set to 1 1    UPDATE 2   TypeScript version 1 4  1 5    1 7 install in 1 4  1 5    1 7 directories  they are not problem to found version  if you have typescript in separate project and you migrate from a previous typescript your project continue to use the old version  to solve this   unload the project file and change the typescript version to 1 x at      lt TypeScriptToolsVersion gt 1 x lt  TypeScriptToolsVersion gt    If you installed the typescript using the visual studio installer file  the path to the new typescript compiler should be automatically updated to point to 1 x directory  If you have problem  review that you environment variable Path include  C  Program Files  x86  Microsoft SDKs TypeScript 1 x    SUGGESTION TO MICROSOFT  -  Because Typescript run side by side with other version  maybe is good to have in the project properties have a combo box to select the typescript compiler  similar to select the net version

If you only have TypeScript installed for Visual Studio then    Start the Visual Studio Command Prompt Type tsc -v and hit Enter     Visual Studio 2017 versions 15 3 and above bind the TypeScript version to individual projects  as this answer points out         Right click on the project node in Solution Explorer   Click Properties   Go to the TypeScript Build tab

Open a  normal  not the VS  command prompt or a PowerShell prompt    tsc exe -v tsc cmd -v tsc -v   If you installed the same version of TypeScript for Visual Studio and using npm  the output from the above three commands should be the same   If not  check your System PATH to see where in the path hierarchy and which typescript directory is listed   For PowerShell users  the easy way is    env path -split       Be careful of having nothing or multiple TypeScript directories listed in your System PATH variable   As of June 9  2017  my System PATH looked like this  just the top part  which is all that matters in this situation    ps gt  env path -split     C  Windows system32 C  Windows C  Windows System32 Wbem C  Windows System32 WindowsPowerShell v1 0  C  Program Files  x86  Microsoft SDKs TypeScript 2 3 C  nodejs  C  Users  username  AppData Roaming npm   Notice that only the 2 3 directory is included in the PATH  not multiple versions

As far as I understand VS has nothing to do with TS installed by NPM    You may notice after you install TS using NPM  there is no tsc exe file   VS targets only tsc exe installed by TS for VS extension  which installes TS to c  Program Files  x86  Microsoft SDKs TypeScript X Y  You may have multiple folders under  c  Program Files  x86  Microsoft SDKs TypeScript  Set TypeScriptToolsVersion to the highest version installed   In my case I had folders  1 0    1 7    1 8   so I set TypeScriptToolsVersion   1 8  and if you run tsc - v inside that folder you will get 1 8 3 or something  however  when u run tsc outside that folder  it will use PATH variable pointing to TS version installed by NPM  which is in my case 1 8 10   I believe TS for VS will always be a little behind the latest version of TS you install using NPM  But as far as I understand  VS doesnt know anything about TS installed by NPM  it only targets whateve versions installed by TS for VS extensions  and the version specified in TypeScriptToolsVersion in your project file

The TypeScript team sorted this out in Visual Studio 2017 versions 15 3 and later  including the free Community edition   How to See Which TypeScript Versions are Installed in Visual Studio  All you now need do is to go to project properties of any TypeScript Visual Studio project  right-click the project file in Solution Explorer Properties   then go to the TypeScript Build tab on the left-hand side   This has a  Typescript version  dropdown that shows you the version the project is using  and if you open it the dropdown shows you ALL versions of TypeScript currently installed in Visual Studio     The actual installs are currently at C  Program Files  x86  Microsoft SDKs TypeScript and then subfolders by version number  at least on Win10 on my computer   If you want to see the exact version  e g  2 8 3 rather than just 2 8  you can find the appropriate tsc exe in here and look at its properties  Details tab in right-click Properties in File Explorer    How to Install Specific TypeScript Version  If you want to install a specific version of TypeScript for Visual Studio  you can download older versions from the Details- Releases section of the TypeScript SDK for Visual Studio 2017 Downloads page   You can verify that the version has been installed either with the  Typescript version  dropdown in VS or inspecting the C  Program Files  x86  Microsoft SDKs TypeScript folder

Two years after the question was asked  using Visual Studio Command Prompt still did not produce right answer for me  But the usual Help About window seems working these days     UPDATE  June 2017     VS 2013 does NOT show this info   Later note  VS 2017 Enterprise edition does not show this info either   VS uses Microsoft Build Engine  MSBuild  to compile Typescript files  MSBuild can support several major releases of Typescript  but About window shows only the latest one    Here is how to get to the bottom of it   A  To check which versions of Typescript are installed with your Visual Studio MSBuild  inspect contents of C  Program Files  x86  Microsoft SDKs TypeScript folder   For example  I have versions 1 0  1 8 and 2 2     B  Check which version of Typescript is requested by your project  In   csproj file  look for  lt TypeScriptToolsVersion gt  tag  or you can add it if it is missing  like this        lt PropertyGroup gt                        lt TypeScriptToolsVersion gt 1 8 lt  TypeScriptToolsVersion gt                   lt  PropertyGroup gt    C  Finally  you can check  which version of Typescript is actually used by MSBuild  In TOOLS   Options   Projects and Solutions   Build and Run set MSBuild project output verbosity to Detailed     Then build your project and inspect the output  you should see the reference to one of Typescript folders described in  A
