dotnet9.0-9.0.119-1.el8_10

.NET is a managed-software framework. It implements a subset of the .NET framework APIs and several new APIs, and it includes a CLR implementation.

New versions of .NET that address a security vulnerability are now available. The updated versions are .NET SDK 9.0.119 and .NET Runtime 9.0.18.
