Injectables not working in angular 2.0

Your compiler does not add parameters properties to the MyAppComponent (from looking at your pluker). I think this is the problem. If you add

MyAppComponent.parameters = [[Names]]

then all will works well.

1. Here is your plunker with fix.
2. Here is the same example in TS (with ES6)

UPD Thanks to @GrayFox for pointing out the correct way (see the comment bellow):

For future references - use --emitDecoratorMetadata flag when using tsc or add emitDecoratorMetadata: true to the configuration if you're using gulp-typescript

See TypeScript compiler options here (you can find emitDecoratorMetada there).

Put this:

 <PropertyGroup Condition=" '$(Configuration)' == 'Debug' " >   <DebugSymbols>true < /DebugSymbols>   < TypeScriptRemoveComments > false < /TypeScriptRemoveComments>   < TypeScriptSourceMap > true < /TypeScriptSourceMap>   < TypeScriptAdditionalFlags > $(TypeScriptAdditionalFlags)--emitDecoratorMetadata < /TypeScriptAdditionalFlags> < /PropertyGroup> < PropertyGroup Condition= " '$(Configuration)' == 'Release' " >   <DebugSymbols>true < /DebugSymbols>   < TypeScriptRemoveComments > true < /TypeScriptRemoveComments>   < TypeScriptSourceMap > false < /TypeScriptSourceMap>   < TypeScriptAdditionalFlags > $(TypeScriptAdditionalFlags)--emitDecoratorMetadata < /TypeScriptAdditionalFlags> < /PropertyGroup>

into your *.njsproj file at the end.
