.SYNOPSIS
|
||
|
|
Occasionally with ORB it is helpful to find all the assemblies under a given folder that reference a specific fragment.
|
||
|
|
|
||
|
|
.PARAMETER ClassNameFragment
|
||
|
|
This is a partial fragment or full class name.
|
||
|
|
The actual comparison looks like this: C# > .GetReferencedAssemblies().Where(x => x.Name.StartsWith(exportedTypeName, StringComparison.InvariantCultureIgnoreCase))
|
||
|
|
|
||
|
|
.PARAMETER Folder
|
||
|
|
Where to look for the DLLs. Will recurse this folder and all subdirectories.
