As a career what are the scopes for C# & VB.Net in future? If someone want to study will it be fine or they’re more better courses than this?

According to TIOBE's index of most popular programming languages, C# and VB.NET are some of the most popular languages used. C# is the5th most popular this year and VB.NET is the13th. In my opinion, there is very little point in learning both C# and VB.NET as they both utilize the .NET framework. Choose the language you are most comfortable with and stick with that.

Web development:

ASP.NET with C# or VB.NET

PHP

Ruby on Rails

Computer:

Java

C++

C# or VB.NET (Windows exclusive)

Objective-C (Mac exclusive)

Mobile:

Java (Android, Blackberry)

 Yes, certainly it has a huge scope as VB.NET also became open source.

Also C# as strong as Java and more strong in some topics.
