You can isolate XLSX parsing in Directum RX by moving the logic into a separate .NET 8 IsolatedArea process. This prevents third-party dependencies from affecting core platform stability.

Yes, Directum RX supports external libraries in an isolated process by using IsolatedArea functions. You wire server calls to Sungero.<Module>.IsolatedFunctions.<Area>.<Method> to execute resource-intensive tasks safely.

You pass data to Directum RX IsolatedArea functions by using contract types limited to serializable primitives, structures, and Stream. Direct entities or repositories cannot be transferred into the isolated environment.

Use IsolatedArea functions for document generation when tasks involve resource-intensive logic or external API calls. Isolating these processes in a separate .NET 8 environment ensures main Directum RX services remain stable.

The best way to structure contracts is defining serializable input and output types, marking shared structures with [Public(Isolated=true)], and creating dedicated Isolated projects in DDS for the function scaffolding.

Directum RX isolated functions fail when passing domain entities because the isolated environment restricts transfers to serializable primitives, structures, and Stream only. Entities and repositories are unsupported inside Isolated code.
