Can someone help me identify what this Solution Explorer icon is. I have reviewed the Images and Icons article from Visual Studio but I don't see a icon similar to this icon. here is the link to the article: https://learn.microsoft.com/en-us/visualstudio/extensibility/ux-guidelines/images-and-icons-for-visual-studio?view=vs-2015
The Icon:
These designate building block type files which may actually span multiple files more than just that one file.
For example one may have a service that has a designer file underneath. Another example is a project installer file (cs) which has the cs file, a designer.cs file and a resx file.
By opening up the file you will see other grouped files underneath.
The files do share the components interface which allows sharing between apps and serves as the basis for all other components in the CLR.
