These kinds of c# interview questions are normally asked to senior people like team lead and above.

Versioning of .NET is done by using 4 part-identifier as shown below:-

So you will find software with version numbers like "10.2.3.107". For instance one of the .NET framework version which was released for SP1 windows 7 edition version number is " 3.5.30729.4926".

So let's try to understand all the four parts in the version identifier.

Major version: - This number is incremented when:-

You break compatibility with previous versions.
Changes are big enough and lots of clients are getting affected.
Major new features are added.
Big UI interface change.
Major changes in database schema etc.
Major change request which can affect lot of client.

In other words this number signifies major changes to the software.

Minor version: - This number is incremented when:-

Compatibility is maintained and some small new features are added.
Serving some minor change request.
You are doing minor changes to the software.

Revision: - This number is incremented when you are normally doing bug fixes, small improvements etc. No new features are added in this scenario.

Build number: - To achieve revisions you need to build your code. This number is incremented every time you do a build.

You can specify the 4 part version identifier by right clicking on visual studio, properties , click on application tab and then on assembly information.
