Mark,
I double-checked this running on the build currently in the My Account area (1.6.7 beta). This appears to be working. So most likely you are having some reference issues or do not have this version of DevExpress installed. This build was compiled for 8.2, so it appears that you are not running this version.
I took a virtual machine, loaded it with the new build, and it works out of the box. So I bet you are just missing a piece. As I mentioned via email, this is the most recent version to which I have access at the moment.
The "First Error" that you received is most likely coming from the change that you made. You probably updated the references, but you did not update the templates. This is where your error came from. A template will try to add the references for you if they are not already in your project. That is what you were getting here.
If you want to change these as well, then you will have to update the templates distributed with StrataFrame. You can find all item templates in the following folder:
C#
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\CSharp
VB.NET
C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates\VisualBasic
These are standard ZIP files. So let's just take the SF_DevEx_MaintenanceForm.zip template. Right click and open the ZIP file (not extract). You will see the contents:
The highlighted file is where the version references can be found. Extract this one file so that you can make changes to it. Once extracted, open the file in VS, notepad, or some other text editor.
As you can see in this example, the DevExpress references are pointing to v8.2. Change these to match your current version. I am not positive, but most likely it will be as follows:
<Reference>
<Assembly>DevExpress.Data.v8.3, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1</Assembly>
</Reference>
<Reference>
<Assembly>DevExpress.Utils.v8.3, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1</Assembly>
</Reference>
<Reference>
<Assembly>DevExpress.XtraBars.v8.3, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1</Assembly>
</Reference>
<Reference>
<Assembly>DevExpress.XtraEditors.v8.3, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1</Assembly>
</Reference>
<Reference>
<Assembly>DevExpress.XtraGrid.v8.3, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1</Assembly>
</Reference>
After the changes have been made, drag this file back into the SF_DevEx_MaintenanceForm.zip file. At this point you are almost done. Next, get out of Visual Studio and run this command:
"C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" /setup
Now, when you go back into VS and use this template, it will use the updated references.
Repeat the same process for each of the other SF_DevEx templates and you will be good to go.
Note: The fact that your error message showed 7.3 for the version, I am willing to bet that you did not get the most recent beta loaded properly or the templates did not get updated as the current version in the most recent build is 8.2.
