Today I have noticed a nice future in visual studio Track Changes.
When you change some code portion in visual studio in says whether you saved it or not. Here is the example for the same.
First I enable the Track Changes in Visual studio. For that go to Tools –> Options –> Text Editor –> General –> (Select) Track Changes.
If you type something in code without saving it will come with a yellow line in the margin.
Once you save this yellow changes to Green.
Summary: This is a nice feature in Visual studio to help us to where we have done the changes in the code before saving the code (Comes as yellow). As well as we come to know which is the last saved one ( comes in green)
