Support for Visual Studio 2026

Last week, Microsoft announced the RTM version Visual Studio 2026, and we have just released a new version of DotVVM for Visual Studio (4.0.588.0) that works with the latest build.

Unfortunately, because of versioning change with the new Visual Studio, we are unable to publish the 2026 extension to the Visual Studio Marketplace yet. If you search for “dotvvm” in the Extension manager, you will still see a version for Visual Studio 2022 that is not going to work in Visual Studio 2026.

Until we find a solution, please download the extension from the Release Notes page in DotVVM Docs.

We already supported Visual Studio 2026 Insiders, and we will continue to release builds for this Insiders version. However, since the Insiders builds are published quite frequently and there may be breaking changes in Visual Studio binary APIs we are using, it is likely we will have some compatibility issues. Please check the Release Notes page before updating Visual Studio to see if that version is supported.

Looking for help

Because of frequent breaking changes in Visual Studio internal APIs we are using (because there are no public APIs for many things our extension needs to do), we want to build a new experience using the Language Server Protocol. The extension would be running out of process and would not have dependencies on particular versions of libraries included in Visual Studio. Thanks to this, we’d also be able to support other IDEs, such as Visual Studio Code or JetBrains Rider. However, this project requires significant effort, and thus, we are looking for help. If you have experience with syntax trees, parsers, or compilers, and would like to help an open-source project, please let us know.
