Deprecating dotMemory Unit

dotMemory Unit has long served as a unit testing framework for detecting memory issues in .NET code. We are grateful to everyone who has used it as part of their development and testing workflows.

After careful consideration, we have decided to retire dotMemory Unit. The project will no longer receive active maintenance, compatibility updates, or security fixes, and we recommend that users plan to discontinue its use.

Why we’re making this change

This decision is based on several technical, security, and product considerations.

dotMemory Unit has not been actively developed for some time and does not support the latest .NET versions. Bringing it up to modern compatibility, reliability, and security standards would require a substantial architectural redesign.

In addition, dotMemory Unit generates workspaces in a legacy format that is incompatible with recent versions of dotMemory. This creates friction for users and prevents seamless integration with the latest JetBrains profiling tools.

Finally, some of the project’s dependencies are outdated and include known security vulnerabilities. Because dotMemory Unit is no longer actively maintained, we cannot reliably update these dependencies without risking compatibility issues or undertaking a full rebuild. Continuing to distribute or support tooling with unpatched vulnerabilities would not meet our security standards.

What this means for you

If you currently use dotMemory Unit, we strongly recommend that you stop using it, especially in security-sensitive environments.

We understand that dotMemory Unit has been valuable for in-test memory profiling, and we recognize that its deprecation may create a gap in some workflows. At this time, we do not have a direct replacement.

Timeline

[20.05.2026]: dotMemory Unit marked as deprecated on NuGet.org. No further updates, patches, or security fixes will be released. 

[28.05.2026]: Official deprecation notice posted across different channels. Documentation will remain online for some time, but will be updated to reflect the current state of the project and potential risks.

Thank you

We are sincerely grateful to everyone who has trusted dotMemory Unit over the years.
