Object reference not set to an instance of an object Follow

Created October 15, 2010 23:05

I get an exception when I have a GroupBy and a var named 'group' and follow R# advice to convert into a LINQ expression. Simplest case example:

foreach (var group in new int[0].GroupBy(n => n))
{
    var x = group.Key;
    if (x == 1) return;
}

The 'foreach' has a squiggly under it. If I choose to convert into a LINQ expression then I will get the null reference exception.

The workaround is to rename 'group' to something else like 'group0'. Then it works fine.

This is with R# 5.1.1753.3.
