When trying to build an application using the Strawberry Shake GraphQL client on our build server, it failed with the following error message:

Build FAILED.
Of course on my local machine everything compiled perfectly. After some trial and error, I discovered that the problem was related to the used SDK version. On the build server I was using the .NET 7 SDK whereas locally I was still using .NET 6.
To align the used versions I introduced a global.json file:
Important: When specifying a version in the global.json file, ALWAYS use the major.minor.patch format (e.g. 6.0.0). I first used ‘6.0’ which doesn’t cause an error but is just ignored. (Took me a long time to discover this!)
The build pipeline will detect this global.json and use the .NET 6 SDK to compile the application.
