Parse Error - While compiling / debugging ASP.Net application

Working in .Net 2.0, Recently, I came across one problem; a FIPS (Federal Information Processing Standards) related error on the .aspx pages which were having debug=”true”.

My ASP.net application was hosted on IIS7 running on WindowsXP. further I was using Visual Studio 2005 Professional Edition. Even I was not able to compile my project.

Error was:
“Parser Error Message: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.” when .net page has debug=”true”

and Error screen-shot was:

To resolve the problem,

(1) Goto Run window in Start Menu and type "regedit" to open Registry editor.
(2) Find key fipsalgorithmpolicy in [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
Its value would be dword:00000001 => which mean
(3) Remove key "fipsalgorithmpolicy"

Enjoy
