Description
We are using T4 text transformation with Visual Studio 2022 with .net 8, where the transformation using TextTransformCore.exe worked correctly.
After upgrading to Visual Studio 2026 and .net 10, the same transformation now fails with the following error:
`Running transformation: System.IO.FileNotFoundException: Could not load file or assembly
'System.Runtime, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
The system cannot find the file specified.
`
The command used:
`"C:\Program Files\Microsoft Visual Studio\18\Professional\Common7\IDE\TextTransformCore.exe" "E:\S\Sgc.Web\Business.Import\Parameters\Reporting\Others\Report_Filter_Properties.tt"
`
This issue did not occur with Visual Studio 2022 TextTransformCore.exe , and the same .tt file works correctly with .NET 8 when transformed
