VS2015 returns JsErrorScriptException when compilerOptions.watch is true

[Liero]

In Visual Studio 2015 create TypeScript HTML app.
Add .ts file to the project
Add tsconfig.json to the project and set "watch": true

{
  "compileOnSave" : true,
  "compilerOptions": {
    "watch": true,
    "noImplicitAny": false,
    "noEmitOnError": true,
    "removeComments": false,
    "sourceMap": true,
    "target": "es5"
  },
  "exclude": [
    "node_modules",
    "wwwroot"
  ]
}

Build the project. Build should fail with an error:

VSTSC : Script failed with error : 'JsErrorScriptException (0x30001)'.

I'm using:
VS2015 Enterprise Version 14.0.24720.00 Update 1
Typescript 1.8.6.0
WebEssentials 2015.1, build 1.0.209
Resharper 2015.2, build 103.0.20150818.200216 (I've tried to suspend it in order to eliminate influence)

I also still have this error with
VS2015 Enterprise Version 14.0.24720.00 Update 1
Typescript 1.8.6.0

The issue has been fixed in master. it is available in the nightly nuget package, and will be available in the nextrelease. TS 1.8.* does not have that.

Either way, the fix is to show a valid error message instead of crashing. but --watch is still an invalid argument to pass to tsc.exe.

@mhegazy Thank you very much for quick answer. I understand the first part of your answer, that this bug is only fixed in the upcomming 2.0 version. But how can I compile the *.ts sources to *.js sources (in Visual Studio 2015) by saving the *.ts?

[mhegazy]

set "compileOnSave": true but note this is not in the "compilerOptions". i.e

{
  "compileOnSave": true,
  "compilerOptions": { ... },
  "exclude": [] 
}

see https://github.com/Microsoft/TypeScript/wiki/tsconfig.json#compileonsave for more details.
