Microsoft .NET Framework 4.8 Coming With Service Pack 29

Pat Conley

Background information:
On April 26, 2022, Microsoft will end support for .NET Framework 4.5.2/4.6/4.6.1, including no longer providing security fixes.

As a security best practice, Blackbaud CRM™ (BBCRM) and Blackbaud Internet Solutions™ (BBIS) will be compiled against Microsoft’s .NET Framework 4.8 starting with Service Pack 29 (scheduled to release in November 2021). This may affect your customizations as assemblies referencing BBCRM or BBIS must now be compiled against .NET Framework 4.8. Our research shows that existing assemblies generally continue to function, but our recommendation is to recompile customizations against .NET Framework 4.8 to ensure compatibility.


What actions do I need to take?

If you are hosted by Blackbaud:

Before upgrading to SP29, we recommend that you compile (or recompile) all customizations against .NET Framework 4.8. This ensures that customizations and third-party integrations will continue to function.

If you are not hosted:

Before upgrading to SP29, install .NET Framework 4.8, if you have not done so already. Next, we recommend that you compile (or recompile) all customizations against .NET Framework 4.8. These two steps ensure that customizations and third- party integrations will continue to function.

Questions?

If you have additional questions or concerns regarding this change, reach out to Blackbaud support.
