+# Deprecation Notice
+## Effective Date: 20 August 2024
+As of 20 August 2024, we will no longer support Visual Studio 2015, 2017, and 2019. Please upgrade to Visual Studio 2022 to continue receiving updates, security patches, and technical support.
+
+# Visual Studio extension
+
+The Snyk Visual Studio extension provides analysis of your code and open-source dependencies. Download the plugin at any time free of charge and use it with any Snyk account. Scan your code early in the development lifecycle to help you pass security reviews and avoid costly fixes later in the development cycle.
+
+Snyk scans for vulnerabilities and returns results with security issues categorized by issue type and severity.
+
+For open source, you receive automated algorithm-based fix suggestions for both direct and transitive dependencies.
+
+This single plugin provides a Java vulnerability scanner, a custom code vulnerability scanner, and an open-source security scanner.
+
+Snyk scans for the following types of issues:
+
+* [**Open Source Security**](https://snyk.io/product/open-source-security-management/) - security vulnerabilities and license issues in both direct and indirect (transitive) open-source dependencies pulled into the Snyk Project.\
+  See also the [Snyk Open Source docs](https://docs.snyk.io/scan-applications/snyk-open-source).
+* [**Code Security**](https://snyk.io/product/snyk-code/) - security vulnerabilities. See also the Snyk Code docs.\
+  See also the [Snyk Code docs](https://docs.snyk.io/scan-applications/snyk-code)_**.**_
+
+In using the Visual Studio extension, you have the advantage of relying on the [Snyk Vulnerability Database](https://security.snyk.io/). You also have available the [Snyk Code AI Engine](https://docs.snyk.io/scan-with-snyk/snyk-code#ai-engine).
+
+This page explains installation of the Visual Studio extension. **After you complete the steps on this page**, you will continue by following the instructions in the other Visual studio extension docs, starting with _**Visual Studio extension configuration**_.
+
+The following are also available:
+
+* [Bug tracker](https://github.com/snyk/snyk-visual-studio-plugin/issues)
+* [Github repository](https://github.com/snyk/snyk-visual-studio-plugin)
+
+The plugin runs on Windows.
