问题
I am running Visual Studio 2015, where people claim that lambda expressions are supported in immediate window, watch and other places. But that does not work for me. I created a new console application with the following code:
static void Main(string[] args)
{
var list = new List<int> {1, 2, 3, 4, 5, 6, 7};
}
And then tried some simple lambdas in immediate window and watch as can be seen here:
And as you can see, it gives me \"Expression cannot contain lambda expressions\". I\'ve looked in tools -> options -> debug settings but could not find anything related to the issue. The version I am running is VS2015 Enterprise, 14.0.24720.00 Update 1 What could be causing this issue?

This definitely works for me, looks like when I tick either Use Managed Compatibility Mode or Use the legacy C# and VB expression evaluators it stops working. Ensure those are unchecked.
