<p dir="auto"><strong>Expected behavior:</strong><br>
Visual Studio's tsc should be able to tell that the module option is set to system.</p>
<p dir="auto"><strong>Actual behavior:</strong><br>
Visual Studio tells me to do something I've already done.</p>
<p dir="auto">Hi all, I have vs 2015 update 1 with ts 1.8. I just tried to reopen an asp.net 5 application with angular 1 and the usual angular.d.ts files.<br>
After the installation of the installation of 1.8 beta I cannot compile it anymore:</p>
<p dir="auto">with 1.8 beta installed I received a lot of errors: <strong>Build: cannot find namespace 'ng'</strong>:<br>
uninstalling it (I have both 1.8 beta and 1.7.6 installed I have a single error: <strong>Unable to get property 'compilerOptions' of undefined or null reference</strong>.<br>
repairing the ts 1.7 installation I obtain this error message: <strong>Option 'project' cannot be mixed with source files on a command line</strong>.</p>
<p dir="auto">I worked with another asp.net 4 project and angular without problems.<br>
this is my tsconfig.json</p>
