Question Mark Dashwood · Feb 10, 2023 I get the following error trying to access Cache using IRIS ADO.NET "InterSystems IRIS Provider is not compatible with Cache xDBC server" Hi I am upgrading our application from dotNet Framework to dotNet Core. Prior to the upgrade I was able to connect to both my Cache & IRIS instances using the IRIS ADO.NET driver. However, in dotNet Core, whilst I can connect to IRIS, I get the following error connecting to Cache. InterSystems IRIS Provider is not compatible with Cache xDBC server I am using the IRIS driver from the Windows (x86-64) 2022.1 distribution (the one in dev\dotnet\bin\net5.0). The cache version is Cache for Windows (x86-64) 2018.1.2 Thanks #.NET #InterSystems IRIS 0 4 0 587
