After installing the AX 2012 R3 CU10 Retail SDK, I opened the Blank Operations VS C# project. After building the solution, I received 2049 errors! It’s gonna be long day, I thought. Here is If you run into this error, here is what you need to do:
Go to each individual project that is missing references in the DevExpress* and SystemSettings DLLs. You will see yellow warning symbols next to the broken references. The screenshot below was taken after I fixed the issue, so you will have to imagine the warnings.
Right click on the project, in this case BlankOperations, and select Properties.
Now select Reference Paths and add the following location:
C:\Program Files (x86)\Microsoft Dynamics AX\60\Retail POS\
Click Add Folder.
Those missing references should now appear visible to the project.
