.NET Uses & Stats

.NET is Used For:
Windows Applications Business Enterprise Applications Software Development Web Applications

Pros
In Demand: 
C# along with Java is one of the top languages in demand for employers. 
 
.Net Library:
C# is integrated with the .Net Library thereby providing access to a vast archive of functionality and support. 
 
Team Friendly:
Multiple developers can easily work together on a project. 
 
Compiled Language:
The code that is stored on a public-facing server is in binary form. In other words, if your server gets hacked, the hacker doesn't automatically have access to your source code. 
 
Transferable:
C# roots are derived from C which means that the structure is transferable to other languages like Java, Objective C, PHP and C++. 
Cons

Steep Learning Curve:
For beginners, C# is not the easiest program to start with. 

Windows Application Exclusively:
Any .NET application needs a Windows platform to execute which means that companies using Linux servers would need Windows hosting to run a .Net application. 
 
Lack of Support for Older .NET:
Many enterprise organizations keep older operating systems because of the many problems that an upgrade can bring to the platform. Microsoft stops supporting older .NET frameworks after a few operating systems upgrades.

Complimentary Skills to have along with .NET

Since the .NET development ecosystem spans a wide array of capabilities and tools, it is difficult for .NET developers to know which .NET development skills and training to pursue in order to increase their marketability — and earning potential.  For that reason, learning supplemental languages such as Java, JavaScript, Python, C/C++, and others is expected in today’s competitive skill-set driven playing field.
