The new version (22.214.171.124) of TDS has been released in March for supporting VS 2017, which is exciting news for Sitecore developers. However, if you installed TDS version 126.96.36.199, you may receive an error message, some thing like “cannot modify an evaluated object originating in an imported file”. If you see this, it is likely because you have modified some of the TDS project properties, within the properties window.
I’ve raised this issue with the TDS support team and they have quickly turned around an update that resolves this issue, version 188.8.131.52. You can download this here.
