MSBuild: Command Line Build error: Solution file error MSB5023: Error parsing the nested project section

Question

I have a solution which uses Solution Folders to split out the projects. In the Visual Studio IDE, the solution builds fine.

However when running the build using MSBuild from the command line, I get the following error:-

Solution file error MSB5023: Error parsing the nested project section in solution file. A project with the GUID "{Some Project GUID}" is listed as being nested under project "{Some Solution Folder Project GUID}", but does not exist in the solution.

Now I've checked these two GUIDs over, and they exist, one as a project, the other as the solution folder that the project is nested under. There shouldn't be any problem.

Does anyone have a way to resolve this?

Answer 1

I faced the same issue and managed to sort out:

1. Opened .sln in NotePad and found Guids
2. One of my projects wasn't closed ("EndProject" was missed)

Cheers, hope this can help anyone
