TeamCity build failing - teamcity

Question

I have a web api project that won't build on teamcity when I add a .net framework (4.71) class library to the solution. If I remove the class library, the build succeeds.

Answer 1

Found the issue. I edited my project file in a text editor and I removed the Deterministic element. The build succeeded after that.
