Common MSBuild project properties
The following table lists frequently used properties that are defined in the Visual Studio project files or included in .targets files that MSBuild provides.
Project files in Visual Studio (.csproj, .vbproj, .vcxproj, and others) contain MSBuild XML code that runs when you build a project by using the IDE. Projects typically import one or more .targets files to define their build process. For more information, see MSBuild .targets files.
List of common properties and parameters
| Property or parameter name | Project types | Description |
|---|---|---|
| AdditionalLibPaths | .NET | Specifies additional folders in which compilers should look for reference assemblies. |
| AddModules | .NET | Causes the compiler to make all type information from the specified files available to the project you are compiling. This property is equivalent to the /addModules compiler switch. |
| ALToolPath | .NET | The path where AL.exe can be found. This property overrides the current version of AL.exe to enable use of a different version. |
| ApplicationIcon | .NET | The .ico icon file to pass to the compiler for embedding as a Win32 icon. The property is equivalent to the /win32icon compiler switch. |
| ApplicationManifest | All | Specifies the path of the file that is used to generate external User Account Control (UAC) manifest information. Applies only to Visual Studio projects targeting Windows Vista. In most cases, the manifest is embedded. However, if you use Registration Free COM or ClickOnce deployment, then the manifest can be an external file that is installed together with your application assemblies. For more information, see the NoWin32Manifest property in this topic. |
| AssemblyOriginatorKeyFile | .NET | Specifies the file that's used to sign the assembly (.snk or .pfx) and that's passed to the ResolveKeySource task to generate the actual key that's used to sign the assembly. |
| AssemblySearchPaths | .NET | A list of locations to search during build-time reference assembly resolution. The order in which paths appear in this list is meaningful because paths listed earlier takes precedence over later entries. |
| AssemblyName | .NET | The name of the final output assembly after the project is built. |
| BaseAddress | .NET | Specifies the base address of the main output assembly. This property is equivalent to the /baseaddress compiler switch. |
| BaseIntermediateOutputPath | All | The top-level folder where all configuration-specific intermediate output folders are created. The default value is obj\. The following code is an example: <BaseIntermediateOutputPath>c:\xyz\obj\</BaseIntermediateOutputPath> |
| BaseOutputPath | All | Specifies the base path for the output file. If it is set, MSBuild will use OutputPath = $(BaseOutputPath)\$(Configuration)\. Example syntax: <BaseOutputPath>c:\xyz\bin\</BaseOutputPath> |
| BuildInParallel | All | A boolean value that indicates whether project references are built or cleaned in parallel when Multi-Proc MSBuild is used. The default value is true, which means that projects will be built in parallel if the system has multiple cores or processors. |
| BuildProjectReferences | All | A boolean value that indicates whether project references are built by MSBuild. Automatically set to false if you are building your project in the Visual Studio integrated development environment (IDE), true if otherwise. -p:BuildProjectReferences=false can be specified on the command line to avoid checking that referenced projects are up to date. |
| CleanFile | All | The name of the file that will be used as the "clean cache." The clean cache is a list of generated files to be deleted during the cleaning operation. The file is put in the intermediate output path by the build process. This property specifies only file names that do not have path information. |
| CodePage | .NET | Specifies the code page to use for all source-code files in the compilation. This property is equivalent to the /codepage compiler switch. |
| CompilerResponseFile | .NET | An optional response file that can be passed to the compiler tasks. |
| Configuration | All | The configuration that you are building, generally Debug or Release, but configurable at the solution and project levels. |
| CscToolPath | C# | The path of csc.exe, the C# compiler. |
| CustomBeforeMicrosoftCommonTargets | All | The name of a project file or targets file that is to be imported automatically before the common targets import. |
| DebugSymbols | All | A boolean value that indicates whether symbols are generated by the build. Setting -p:DebugSymbols=false on the command line disables generation of program database (.pdb) symbol files. |
| DebugType | All | Defines the level of debug information that you want generated. Valid values are "full," "pdbonly," "portable", "embedded", and "none." |
| DefineConstants | .NET | Defines conditional compiler constants. Symbol/value pairs are separated by semicolons and are specified by using the following syntax: symbol1 = value1 ; symbol2 = value2 The property is equivalent to the /define compiler switch. |
| DefineDebug | All | A boolean value that indicates whether you want the DEBUG constant defined. |
| DefineTrace | All | A boolean value that indicates whether you want the TRACE constant defined. |
| DelaySign | .NET | A boolean value that indicates whether you want to delay-sign the assembly rather than full-sign it. |
| Deterministic | .NET | A boolean value that indicates whether the compiler should produce identical assemblies for identical inputs. This parameter corresponds to the /deterministic switch of the compilers. |
| DisableFastUpToDateCheck | All | A boolean value that applies to Visual Studio only. The Visual Studio build manager uses a process called FastUpToDateCheck to determine whether a project must be rebuilt to be up to date. This process is faster than using MSBuild to determine this. Setting the DisableFastUpToDateCheck property to true lets you bypass the Visual Studio build manager and force it to use MSBuild to determine whether the project is up to date. |
| DocumentationFile | .NET | The name of the file that is generated as the XML documentation file. This name includes only the file name and has no path information. |
| ErrorReport | .NET | Specifies how the compiler task should report internal compiler errors. Valid values are "prompt," "send," or "none." This property is equivalent to the /errorreport compiler switch. |
| ExcludeDeploymentUrl | .NET | The GenerateDeploymentManifest task adds a deploymentProvider tag to the deployment manifest if the project file includes any of the following elements: - UpdateUrl - InstallUrl - PublishUrl Using ExcludeDeploymentUrl, however, you can prevent the deploymentProvider tag from being added to the deployment manifest even if any of the above URLs are specified. To do this, add the following property to your project file: <ExcludeDeploymentUrl>true</ExcludeDeploymentUrl> Note: ExcludeDeploymentUrl is not exposed in the Visual Studio IDE and can be set only by manually editing the project file. Setting this property does not affect publishing within Visual Studio; that is, the deploymentProvider tag will still be added to the URL specified by PublishUrl. |
| FileAlignment | .NET | Specifies, in bytes, where to align the sections of the output file. Valid values are 512, 1024, 2048, 4096, 8192. This property is equivalent to the /filealignment compiler switch. |
| FrameworkPathOverride | Visual Basic | Specifies the location of mscorlib.dll and microsoft.visualbasic.dll. This parameter is equivalent to the /sdkpath switch of the vbc.exe compiler. |
| GenerateDocumentation | .NET | A boolean parameter that indicates whether documentation is generated by the build. If true, the build generates documentation information and puts it in an .xml file together with the name of the executable file or library that the build task created. |
| GenerateFullPaths | C# | Generate full paths for filenames in output by using the -fullpaths compiler option. |
| GenerateSerializationAssemblies | .NET | Indicates whether XML serialization assemblies should be generated by SGen.exe, which can be set to on, auto, or off. This property is used for assemblies that target .NET Framework only. To generate XML serialization assemblies for .NET Standard or .NET Core assemblies, reference the Microsoft.XmlSerializer.Generator NuGet package. |
| IntermediateOutputPath | All | The full intermediate output path as derived from BaseIntermediateOutputPath, if no path is specified. For example, obj\debug\. |
| KeyContainerName | All | The name of the strong-name key container. |
| KeyOriginatorFile | All | The name of the strong-name key file. |
| ModuleAssemblyName | .NET | The name of the assembly that the compiled module is to be incorporated into. The property is equivalent to the /moduleassemblyname compiler switch. |

| MSBuildTreatWarningsAsErrors | All | A boolean value that tells MSBuild to treat all warnings as errors, unless they're suppressed. |
| MSBuildWarningsAsErrors | All | Specifies a list of warning codes to treat as errors. Separate multiple warnings by semicolons. If you are using the .NET SDK property WarningsAsErrors, MSBuildWarningsAsErrors will default to the value of WarningsAsErrors. |
| MSBuildWarningsAsMessages | All | Specifies a list of warning codes to suppress by treating them as low-importance messages. Separate multiple warnings by semicolons. Note that some warnings emitted by MSBuild cannot be suppressed by using this property; to suppress them, use the command-line switch -warnAsMessage. If you are using the .NET SDK property NoWarn, MSBuildWarningsAsMessages will default to the value of NoWarn. |
| NoLogo | All | A boolean value that indicates whether you want compiler logo to be turned off. This property is equivalent to the /nologo compiler switch. |
| NoStdLib | .NET | A boolean value that indicates whether to avoid referencing the standard library (mscorlib.dll). The default value is false. |
| NoVBRuntimeReference | Visual Basic | A boolean value that indicates whether the Visual Basic runtime (Microsoft.VisualBasic.dll) should be included as a reference in the project. |
| NoWarn | .NET | Suppresses the specified warnings. Only the numeric part of the warning identifier must be specified. Multiple warnings are separated by semicolons. This parameter corresponds to the /nowarn switch of the compilers. |
| NoWin32Manifest | .NET | A boolean value that indicates whether User Account Control (UAC) manifest information will be embedded in the application's executable. Applies only to Visual Studio projects targeting Windows Vista. In projects deployed using ClickOnce and Registration-Free COM, this element is ignored. False (the default value) specifies that User Account Control (UAC) manifest information be embedded in the application's executable. True specifies that UAC manifest information not be embedded.This property applies only to Visual Studio projects targeting Windows Vista. In projects deployed using ClickOnce and Registration-Free COM, this property is ignored. You should add NoWin32Manifest only if you do not want Visual Studio to embed any manifest information in the application's executable; this process is called virtualization. To use virtualization, set <ApplicationManifest> in conjunction with <NoWin32Manifest> as follows:- For Visual Basic projects, remove the <ApplicationManifest> node. (In Visual Basic projects, <NoWin32Manifest> is ignored when an <ApplicationManifest> node exists.)- For C# projects, set <ApplicationManifest> to False and <NoWin32Manifest> to True. (In C# projects, <ApplicationManifest> overrides <NoWin32Manifest>.)This property is equivalent to the /nowin32manifest compiler switch of vbc.exe. |
| Optimize | .NET | A boolean value that when set to true, enables compiler optimizations. This property is equivalent to the /optimize compiler switch. |
| OptionCompare | VisualBasic | Specifies how string comparisons are made. Valid values are "binary" or "text." This property is equivalent to the /optioncompare compiler switch of vbc.exe. |
| OptionExplicit | Visual Basic | A boolean value that when set to true, requires explicit declaration of variables in the source code. This property is equivalent to the /optionexplicit compiler switch. |
| OptionInfer | Visual Basic | A boolean value that when set to true, enables type inference of variables. This property is equivalent to the /optioninfer compiler switch. |
| OptionStrict | Visual Basic | A boolean value that when set to true, causes the build task to enforce strict type semantics to restrict implicit type conversions. This property is equivalent to the /optionstrict switch of the vbc.exe compiler. |
| OutDir | All | Indicates the final output location for the project or solution. When building a solution, OutDir can be used to gather multiple project outputs in one location. In addition, OutDir is included in AssemblySearchPaths used for resolving references. For example, bin\Debug. |
| OutputPath | All | Specifies the path to the output directory, relative to the project directory, for example, bin\Debug. |
| OutputType | All | Specifies the file format of the output file. This parameter can have one of the following values: - Library. Creates a code library. (Default value.) - Exe. Creates a console application. - Module. Creates a module. - Winexe. Creates a Windows-based program. For C# and Visual Basic, this property is equivalent to the /target switch. The output type can be automatically overridden by inferencing. See OutputType set to WinExe for WPF and WinForms apps. Disable inferencing by setting DisableWinExeOutputInference to true. |

| UseCommonOutputDirectory | .NET | A boolean property that you can set to true when you want all build outputs in a solution to use the same output directory. If true, referenced projects' output is not copied to projects that use those dependencies, as is normally the case when this setting is false. Setting this parameter to true does not change the actual output directory of any projects; you still need to set the output directory to the desired common output directory for each project that requires it. |
| UseHostCompilerIfAvailable | .NET | A boolean parameter that, if true, causes the build task to use the in-process compiler object, if it is available. This parameter is used only by Visual Studio. |
