<p><a href="https://nuget.episerver.com/package/?id=CodeAnalyzers.Episerver">Code analyzers for Episerver</a> is a new Roslyn-based plugin that analyzes your Episerver code as you type. It can help you avoid some problems with editor experience and code maintainability.<br />The plugin will show live warnings ("squiggles") in Visual Studio while you are typing.</p> <h3>Analyzers</h3> <p>Inspired by a <a href="https://www.epinova.no/en/blog/episerver-content-types-hygiene-unit-tests/">recent blog post</a>, Code analyzers for Episerver looks for the correct use of content type and property attributes to ensure a good experience for your editors.<a href="https://www.epinova.no/en/blog/episerver-content-types-hygiene-unit-tests/"></a></p> <p>The analyzer rules can be configured individually and phased in gradually in a larger codebase.</p> <p><img src="/link/78830ea78e2142259d8f8aa7d254ad70.aspx" /></p> <p>Code analyzers for Episerver also looks for the use of known legacy types and 'Internal' namespaces that should be avoided in your code.</p> <p><img src="/link/ccccafb56bee4aeb88f5fc85fd021acb.aspx" /></p> <h3>Configuration</h3> <p>Each analyzer rule severity can be configured in a <a href="https://docs.microsoft.com/visualstudio/code-quality/using-rule-sets-to-group-code-analysis-rules">ruleset file</a> similar to Visual Studios built-in code analysis.</p> <h3>Installation</h3> <p>Code analyzers for Episerver is installed per-project as a NuGet package from the <a href="https://nuget.episerver.com/package/?id=CodeAnalyzers.Episerver">Episerver feed</a>.</p> <p>Visual Studio automatically detects and executes the analyzers. Build servers will also execute the analyzer rules on every build.</p> <h3>Compatibility</h3> <p>Code analyzers for Episerver is compatible with the compilers in Visual Studio 2019 and Visual Studio 2017 (15.5+).</p> <p>If your project references an old version of the <a href="https://www.nuget.org/packages/Microsoft.Net.Compilers/">Microsoft.Net.Compilers</a> package you may need to upgrade this to 2.6.1+ for compatibility with Code analyzers for Episerver.</p>
