The solution I tried to convert is very large - a single project with more than 1200 files and god knows how many lines of code.
There are about 700 occurrences of this #error Cannot convert InvocationExpressionSyntax.
I don't see a clear pattern, but it seems to affect many calls of Singletons (like the above LicenseService), but not exclusively.
Many of them - like the above example - I can simply fix by removing the error comment and putting the line exactly as shown in the expected output above.
