"Solve all your problems using .Net 4.5"
4.5/5
What do you like best about .NET 4.5?

When attempting to develop applications for our clients, .Net has been our faithful companion for the past few years. Through it, we've been able to fulfill all of our programming needs, from developing interactive webapps to dynamic websites. When it came to security features, .Net is easily one of the more secure programming frameworks as it is owned by Microsoft and backed up by 100s of thousands of developers. One of our latest projects was for a pharmaceutical warehouse where we connect all of their branches to a core database through an off the shelf point of sale system. We managed to do this with ease and had the support of the community when trying to resolve all of our issues. Review collected by and hosted on G2.com.

What do you dislike about .NET 4.5?

As .NET is owned by Microsoft, the framework is strongly focused on the Windows OS. Recently Microsoft released .Net core to try and address the MacOS and Linux support. .Net can be costly if you look into bringing additional features on board (like team development infrastructure and add-ons) While it is easy to learn and pick up, optimization is a must for big projects, as the code can become resource draining if not optimized properly.

What do you like best about .NET 4.5?

A comprehensive set of tools I can use in my software development. Review collected by and hosted on G2.com.

What do you dislike about .NET 4.5?

At least I always write in the same framework (.NET), and do not require to look up documentation to know how routine things are done. The inflexibility of those tools, if changes are required. Such that if I have to create a custom UI, I either use the existing set provided, or have to start one from scratch, with no middle ground such as the possibility of tweaking the source code of the existing controls, since no source code for the entire .NET 4.5 platform has ever been provided in any form.

What do you like best about .NET 4.5?

.Net is one of the core platforms used by most big companies. It supports dominant programming languages like C#, C++, and VB.net. A key feature of .Net is the Common Language Runtime, allowing you to write code in different languages for the same project. .Net 4.5 also has a powerful garbage collection system that handles many tasks in the background. As a developer, I rarely worry about the garbage collector because it automatically frees memory occupied by objects no longer in use by the program. Review collected by and hosted on G2.com.

What do you dislike about .NET 4.5?

.Net is not entirely open source. The .Net framework has so many components that it becomes hard to tell what's new and what's old :( Review collected by and hosted on G2.com.
