Conditional Compliation Constant VB

Error   BC31030 Conditional compilation constant '; ^^ ^^ EXCLUDE_CODEGEN' is not valid: Identifier expected.   GpsHost C:\Projects\GpsTrackSolution\GpsHost\vbc    1   N/A

I am getting the above error when I try and build a VB.NET win forms app. I refactored it a little, updated to framework 4.7.2 and now I am getting this.

There is NO reference in ANY vbproj for that string of characters, either partial or full. I've done a find in file contents across the entire solution and cannot find that anywhere. Almost at my wit's end as to what could be doing this.

Solution

  • This was unrelated to VB, it was actually due to Orleans code generation trying to insert constants. Orleans isn't really designed to work with VB, so I switched to runtime codegen, instead of build time, and it worked.
