Description

Our application that uses large C++/CLI assemblies starts slower than it did on .net framework 4.8. Profiling shows a lot of JIT activity but Crossgen2 reports

Error: Error: managed C++ is not supported: <dll name>

Configuration

x64 windows.

Regression?

Yes. NGEN on .net framework used to work for C++/CLI assemblies.

Data

According to PerfView results ~20% of startup is spent in JIT.
