Are there any details regarding contributing? and or getting the solution to compile etc.?

I've encountered various issue trying to compile & run unit tests
(Win10, VS2022, branch stable)

• Solution file format VS2019 won't work because of no support for .Net6 SDK
• Nuget configuration missing/wrong
  Error NU1507 There are 5 package sources defined in your configuration. When using central package management, please map your package sources with package source mapping (https://aka.ms/nuget-package-source-mapping) or specify a single package source.
  Adding Nuget.config from main branch seems to fix this
• Tests rely on Postgres installed locally
  No instructions on on this, eg Postgres versions needed
  No details on 'npgsql_tests' role needed eg permissions. (or a script to create the role)
• 6117 of 16826 tests fail
  some examples:

Npgsql.EntityFrameworkCore.PostgreSQL.CommandInterceptionNpgsqlTestBase+CommandInterceptionNpgsqlTest.Intercept_non_query_one_app_and_one_injected_interceptor(async: False)
Npgsql.PostgresException : 53300: sorry, too many clients already
