Hi,

I am working with Xoml(With code separation) files. Code is written seperately in another project and adding the above as Base class for Xoml file, then removing x:Class from Xoml file. When building the project I am getting the error like cannot compile a markup file which does not contain declaration of the new workflow type. If I keep x:class attribute then I am getting WorkflowValidationFailedException at runtime.

This build error is creating the problem at the time of deployment. So, anybody please help me in solving this problem. Currently I am working with Workflow Beta 2.2 version.

Thank you

Satya

You should probably upgrade to a more recent build, like RC5, because it will probably be the build that is released. That being said, are you calling CreateWorkflow using one of the Type parameter overloads or XmlReader? If you are going to compile a code seperated workflow into a type you need the x:Class attribute. If you are passing an XmlReader to CreateWorkflow you can not include the attribute. Using the xml reader is called XAML Activation. For more information on that take a look at the blog posts here. If you are using one of the Type parameter overloads and getting the WorkflowValidationFailedException you should catch the exception and check the Errors property like the following:

Hi Tom,

You also need to change the properties on the XOML file in your project so that VS does not try to compile it. Set it to NONE and then decide if you want to copy the file the output directory or not.

If you don't do this, VS will still try to compile it, but fail because you do not have the x:class attribute in the file (which is what you want for XAML activation).

Hi Matt,

Thank you for your valuable solution. I have changed the Xoml file's BuildAction property to None from Content. Now I am not getting the above error while building.

Thank you
