Swashbuckle.aspnetcore: Can't build with RC3 in VS2019 / .Net Core 3.0

[SledgeHammer01]

When I try to build my project in VS2019 with .Net Core 3.0 and Swagger 5.0 RC3, I get the following build error. RC2 builds fine.

Severity Code Description Project File Line Suppression State

I had a similar issue with net core 2.2 - https://github.com/domaindrivendev/Swashbuckle.AspNetCore/issues/1266

try setting the following property in the csproj

<OpenApiGenerateDocuments>false</OpenApiGenerateDocuments>

I have the same issue after upgrade to RC3 and .Net Core 3.0.
RC2 builds fine
