File paths in tsconfig exclude are not respected in NTVS build

[BigDataSamuli]

TypeScript Version:

1.8.2

Code

foo.ts

var foo: number = "s";

tsconfig.json

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es5"
    },
    "exclude": [
        "foo.ts"
    ]
}

Expected behavior:

In an NTVS typescript console application using the above tsconfig.json, and a file foo.ts containing an error, the build and run initiated by Visual Studio should succeed because the file containing the error is excluded.

Actual behavior:

The build fails with an error in foo.ts. Compiling from command line, the build succeeds. Also, if foo.ts is put inside a folder, and the folder is listed in the exclude array, the VS build succeeds.

This is currently breaking projects using the typings tool, because it generates two sets of type definitions, and the other set cannot be excluded.

What version of Visual Studio (2013 / 2015?) are you using?

[BigDataSamuli]

VS 2015 Pro. Happens with the non-NTVS "HTML Application with Typescript" project as well. I also have TS Tools 1.7.6 installed. If you can't reproduce, I'll try reinstalling some stuff.

Can you give TS 1.8 (https://blogs.msdn.microsoft.com/typescript/2016/02/22/announcing-typescript-1-8-2) a try. tsconfig.json should be supported as the main source of configuration, which was not the case in 1.7.*

[BigDataSamuli]

Sorry, I have 1.8 installed, but I also have the older version installed. I'll try uninstalling all versions and only installing the newest one.

[BigDataSamuli]

Removed all TS Tools versions, reinstalled only 1.8.4, the issue remains. Also tested on another machine, same problem.

can you share your build log?

Here's the log (from the output window): http://pastebin.com/iwVEEkS3

Looks like I get the same error if I run the build command from the log in command prompt, that is:
"C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.8\tsc.exe" --project "C:\dev\test5\tsconfig.json"

However, running without the --project switch, the build completes successfully (and the tsconfig used is the same).

Even more strangely:

C:\dev\test5>"C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.8\tsc.exe" --project "C:\dev\test5\tsconfig.json"

gives the error but

C:\dev\test5>"C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.8\tsc.exe" --project "tsconfig.json"

doesn't.

Ok. thanks for the information. i think i have found the issue. some background, tsc.exe is just a wrapper around tsc.js with ChakraCore. The IO operations has a diffrent implementation for tsc.exe and node tsc.js.
Looks like the readDirectory logic in tsc.exe implementation did not exclude files, only directories. i have queued up a fix for it, and should be in the next nightly nugget release: https://www.myget.org/gallery/typescript-preview (see https://github.com/Microsoft/TypeScript/wiki/Nightly-drops#using-nuget-with-msbuild for more information).
