MVC App Works in Visual Studio, but not IIS7

Question

Working on a an ASP.NET MVC Project, and I'm having some difficulties deploying to a shared dev server.

Locally, when debugging using the local Visual Studio 2008 server, everything works peachy. However, once deployed, I receive the following error:

    Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.## Heading ##

Parser Error Message: Unable to find an entry point named 'BCryptGetFipsAlgorithmMode' in DLL 'bcrypt.dll'.

Custom event details:

After finding the deployment error, I tried adding an application locally, and that seems to result in the same application.

On my local dev machine, I'm using Windows 7 RTM (x64), and on the shared server I'm running Windows Server 2008 Standard (x86).

Poked around, and my FIPS encryption in Local Security Policy is disabled, so I'm at a bit of a loss.

Answer 1

I had some issues in the past when developing on a x64 and deploying to a x86 environment. Under the platform target are you compiling to "Any CPU", x86 or x64?

Try compiling directly to x86 and see if that gives helps.

Answer 2

Are you using Bcrypt.net from here? If so you need to build it with a different dll name (so for example build it as BCryptNet.dll)

The problem is that there is a new windows API in Vista/Windows 2008 that tries to load bcrypt.dll and if you have a bcrypt.dll in your web app bin/ directory it can't find the system dll.
