AppDomainSetup.DynamicBase is no longer randomized by UseRandomizedStringHashAlgorithm

Scope

Edge

Version Introduced

4.6

Source Analyzer Status

Planned

Change Description

Prior to the .NET Framework 4.6, the value of xref:System.AppDomainSetup.DynamicBase would be randomized between application domains, or between processes, if UseRandomizedStringHashAlgorithm was enabled in the app's config file. Beginning in the .NET Framework 4.6, xref:System.AppDomainSetup.DynamicBase will return a stable result between different instances of an app running, and between different app domains. Dynamic bases will still differ for different apps; this change only removes the random naming element for different instances of the same app.

  • Quirked
  • Build-time break

Recommended Action

Be aware that enabling UseRandomizedStringHashAlgorithm will not result in xref:System.AppDomainSetup.DynamicBase being randomized. If a random base is needed, it must be produced in your app's code rather than via this API.

Affected APIs

  • P:System.AppDomainSetup.DynamicBase
