Error in callout (ISV code threw exception)

Question

Hi,

Wrote a simple callout with "PostCreate" method. Seems there is some problem calling the callout. I use CRM 3.0

Also, is it mandatory to develop callout using VS.Net 2003 ? I use VS 2005.

Please find error from eventlog and let me know what am i missing:

---------------------------------

Answer 1

I think you are using a 32 bit version of the CRM sdk dll when it should be 64 bit....or vice versa.  Typically that is the reason for an BadImageFormatException

Blake,

Which dll you are referring to ? I have only referred Microsoft.Crm.Platform.Callout.Base.dll in my VS 2005 project.

Answer 3

Are you using .Net 2.0?  It might have to be set to .Net 1.1 to use that dll

When i run the MSBee setup, it says it needs .Net framework 1.1 SDK which is again not available for download.
