Comand line Comparison not working if extension is not lowercase

[sebastianslutzky]

Steps to reproduce it

Run the following powershell command

&"C:\Program Files (x86)\Telerik\JustAssembly\Libraries\JustAssembly.CommandLineTool.exe" "E:\git\compare\current\content\lib\ikvm\JVM.DLL" "E:\git\compare\server\content\lib\ikvm\JVM.DLL" "JVM.DLLJVM.DLL.xml"

Expected Result

Assembly comparison should execute and succeed

Actual Result

Error with message
First assembly path is in incorrect format or file not found.
Exit code: 1

workaround:

lower casing the file extensions for both inputs worked well

&"C:\Program Files (x86)\Telerik\JustAssembly\Libraries\JustAssembly.CommandLineTool.exe" "E:\git\compare\current\content\lib\ikvm\JVM.dll" "E:\git\compare\server\content\lib\ikvm\JVM.dll" "JVM.DLLJVM.DLL.xml"

Possible cause:

This class:
https://github.com/telerik/JustAssembly/blob/master/UI/JustAssembly.CommandLineTool/FilePathValidater.cs#L30

should be validating the input file extensions regardless their casing. at the moment, only lowercase "dll" or "exe" are valid inputs
