Using a custom build for the compiler

[alrz]

Feature Description

Having a local build of roslyn, would it be possible to use that binary instead?

This is currently not configurable.

As a workaround, you could probably (but I haven't tried) just manually replace Roslyn's dlls at %userprofile%\.dotnet\tools\.store\csharprepl\0.6.5\csharprepl\0.6.5\tools\net7.0\any (of course, supposing that its public API surface hasn't changed).

Perhaps we could add a configurable Roslyn location to cfg.
