When writing my C# code I was in the habit of using string (all lowercase) for strings declarations, etc. and String (capitalized) for method calls such as String.Empty and String.Format just as a sort of aide memoir that I was calling an object method.
As I started to create String extension methods I reviewed this habit of mine and decided this was a pointless differentiation and switched to just using string all the time. At the same time I decided that my using Int32 for methods such as Int32.TryParse and just int in declarations, etc. was also pointless and perhaps confusing to others and so switched to using int all the time instead.
It all compiles to the same IL code anyway so it was just a matter of style really.
What do you think?

I used to think that String referred to a class, whereas string was just a simple type. I believe at some point in the past this was the case?? However, I now just use the lower case variant for simplicity.

Nope, never. It's just an alias.
string
Visual Studio .NET 2003
The string type represents a string of Unicode characters. string is an alias for System.String in the .NET Framework.

And now, is it important?

Could it be that you are confusing this with Java? .Net never had primitive types. One of the most important differences when the Java guys still dismissed c# as a bad copy of Java.
The language is JavaScript. that of Mordor, which I will not utter here
This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a f***ing golf cart.
"I don't know, extraterrestrial?"
"You mean like from space?"
"No, from Canada."

No. I never studied Java. I probably was just confusing it with.....

.Net really never had primitive types, but down below I just heard that the line between the classes and the aliases as value types is not drawn as clearly as I believed.

I also prefer the differentiation, and I know other Code Projectors have said the same thing.
I dislike the aliases and I'd rather they weren't built in -- let the user define them as required.
What I find crazy is that when specifying the underlying type for an enumeration, you must use the alias. 
And think I recall that there's a place where you mustn't use the alias.

Not if you're using the Roslyn (C# 6 / VS2015) compiler:
enum Foo : Int32
{
Bar,
Baz,
}

No thanks. I prefer to write backward-compatible code unless there's a real reason to do otherwise.

There is a tiny difference, remember? Classes are reference types while the aliases are made to appear like value types for convenience.

Classes are reference types but Int32 is a struct

That explains it. Then I'm right what String and string are concerned, but wrong about Int32 and int.

Nope again. 
String and string are exactly the same - an immutable reference type.
The only reason you don't typically need to use new with a string is because the compiler has a deep knowledge of it.

No, there is no difference.

Ok, then it's time to do some reading.

In case I would ask same here...
It's really a two (at least) class community

I've always used the lowercase string when declaring a type, but I use the uppercase String when calling static methods. For example:
string myString = "Hello World!";
string anotherString = String.Format("{0}", "Hola!");
Microsoft seems to do the same thing, as seen in some of their examples, like here.

If the usage is correct, that make me think why the VS Intellisense still display "name can be simplified", "Show potential fixes", IDE0001 C# Name can be simplified.
Isn't that "Show potential fixes" = there is a bug and here is the potential fix?
After all VS is Microsoft product right?

i'm getting "name can be simplified" since switching to VS2015 Community. (change String to string.)

Now that you have made up your mind, let me generate some doubts again.
It's no secret that value types don't really exist. They are classes, reference types, that are made to behave like value types by the compiler. You can use tham as reference types if you wish by working with the classes. If you want the value type behavior, you use the alias and the compiler does the rest.
The question which one to use is less a question of style. It's more a question of what you want to accomplish and strictly choosing one or the other limits your options without any real need.

Are you sure you're not thinking of Java?
With .NET, there's no difference in behaviour between using the class name or the alias.

Don't think so, when was the last time you had to initialize an int with new() before using it or check for null? Now try that with Int32, which without question is the class that corresponds to int.
