Why would you want to do this? It\u0026rsquo;s already included in your CI/CD pipeline, so you don\u0026rsquo;t need it in your local development environment? The answer is simple: you want to have the same code analysis rules and hints in your local development environment as in your CI/CD pipeline. This way, you can fix issues early and avoid surprises when pushing your code to the repository, and executing maybe long-running CI/CD pipelines.\u003c/p\u003e\n\u003cp\u003eHere\u0026rsquo;s how you can do it:\u003c/p\u003e\n\u003cdiv class=\"highlight\"\u003e\u003cpre tabindex=\"0\" class=\"chroma\"\u003e\u003ccode class=\"language-xml\" data-lang=\"xml\"\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\u003cspan class=\"nt\"\u003e\u0026lt;Project\u003c/span\u003e \u003cspan class=\"na\"\u003eSdk=\u003c/span\u003e\u003cspan class=\"s\"\u003e\u0026#34;Microsoft.NET.Sdk\u0026#34;\u003c/span\u003e\u003cspan class=\"nt\"\u003e\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e  \u003cspan class=\"nt\"\u003e\u0026lt;ItemGroup\u003c/span\u003e \u003cspan class=\"na\"\u003eCondition=\u003c/span\u003e\u003cspan class=\"s\"\u003e\u0026#34;\u0026#39;$(BuildingInsideVisualStudio)\u0026#39; == \u0026#39;true\u0026#39;\u0026#34;\u003c/span\u003e\u003cspan class=\"nt\"\u003e\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e    \u003cspan class=\"nt\"\u003e\u0026lt;PackageReference\u003c/span\u003e \u003cspan class=\"na\"\u003eInclude=\u003c/span\u003e\u003cspan class=\"s\"\u003e\u0026#34;SonarAnalyzer.CSharp\u0026#34;\u003c/span\u003e \u003cspan class=\"na\"\u003eVersion=\u003c/span\u003e\u003cspan class=\"s\"\u003e\u0026#34;9.6.0\u0026#34;\u003c/span\u003e \u003cspan class=\"nt\"\u003e/\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e  \u003cspan class=\"nt\"\u003e\u0026lt;/ItemGroup\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e  \u003cspan class=\"c\"\u003e\u0026lt;!-- Rest of the project file --\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\n\u003c/span\u003e\u003c/span\u003e\u003cspan class=\"line\"\u003e\u003cspan class=\"cl\"\u003e\u003cspan class=\"nt\"\u003e\u0026lt;/Project\u0026gt;\u003c/span\u003e\n\u003c/span\u003e\u003c/span\u003e\u003c/code\u003e\u003c/pre\u003e\u003c/div\u003e\n\n\n\n\u003ch2 id=\"beware-of-pitfalls-with-buildinginsidevisualstudio\"\u003e\u003ca href=\"/posts/buildinginsidevisualstudio/#beware-of-pitfalls-with-buildinginsidevisualstudio\" title=\"Beware of Pitfalls with BuildingInsideVisualStudio\"\u003eBeware of Pitfalls with \u003ccode\u003eBuildingInsideVisualStudio\u003c/code\u003e\u003c/a\u003e\u003c/h2\u003e\n\u003cp\u003eWhile the \u003ccode\u003eBuildingInsideVisualStudio\u003c/code\u003e property is a powerful tool for customizing your build process, there are some common pitfalls to be aware of when using it in your project files.
