Loading a solution causes exception at start of Visual Studio 2015 Community

Question

I recently added some extensions to Visual Studio 2015 Community and since then I experience this error message when I load a solution:

I tried to run Visual Studio as administrator and disabled/uninstalled the new extensions, but nothing helps or indicates to the problem.

The log shows this error message:

In the extension manager the typescript extension is grey-ed out:

Any idea other than reinstalling Visual Studio?

Answer 1

The version of Visual Studio is too old / incompatible.

An upgrade to the latest version Visual Studio Update 3 resolves the issue.
