We started using Visual Studio 2022, but after few days we'v got this terrible news: VS2022 doesn't support RDLC designer.
Is there a workaround? Sure we can continue to use VS2019 in parallel, but it's too uncomfortable.
Ok, we have just found this thread:
Developer Community Visual Studio RDLC design in 2022
We'll keep it monitored, but at the moment they don't have release a new tool. A workaround seem to be this (quoted in the link above):
A workaround until the designer is officially supported is to download Microsoft Report Builder and use it in editing your reports, Demo: https://youtu.be/3Wss8bvzjiE
EDIT: Released for 2022!
