All-inclusive .NET assembly manager

DnSpy is a powerful computer package containing appropriate toolsets to address the vague .NET assembly.

They are neatly grouped in standard menus which can easily be accessed at the top of the main screen. Occupying the largest space is the configuration window. 

Here, you have the liberty to modify several settings for different components including the decompiler, debugger, or hex editor. In addition, it allows you to customize the display and other relevant parameters. For instance, you can opt to utilize its light or dark themes. Taking up the smaller area in the home screen is the Assembly Explorer pane, which enables you to access a tree view of a specific assembly. 

There are two methods in opening an assembly. The first one is by simply citing a suitable file existing in your PC or by plainly selecting the ‘Open’ option from the Global Assembly Cache (GAC) which will then give you a list of entries. Apart from the mentioned capabilities, it is also an extensible solution that empowers you to write your own extension but advanced technical knowledge is required.

With an extensive but user-friendly interface, developers will be able to decompile, debug, and edit .NET assemblies with so much ease and achieve quick and satisfactory results. However, this can be challenging for novice users. The huge configuration window permits you to tailor various components to your liking.
