MSBuild reserved and well-known properties
MSBuild provides a set of predefined properties that store information about the project file and the MSBuild binaries. These properties are evaluated in the same manner as other MSBuild properties. For example, to use the MSBuildProjectFile property, you type $(MSBuildProjectFile).
MSBuild uses the values in the following table to predefine reserved and well-known properties. Reserved properties cannot be overridden, and most well-known properties shouldn't be overridden except in advanced scenarios.
Reserved and well-known properties
The table in this section shows the MSBuild predefined properties. The example column in the table relates to the following example project file, assumed to be located at C:\Source\Repos\ConsoleApp1\ConsoleApp1, and shows an example of the values these properties have when accessed in the project file, when MSBuild is invoked with no special command-line options.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp3.1</TargetFramework>
</PropertyGroup>
</Project>
| Property | Reserved or well-known | Description | Example |
|---|---|---|---|
FrameworkSDKRoot |
Well-known | Path to the root folder for .NET Framework tools. | C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\ |
InnerBuildProperty |
Well-known | Specifies the property name that defines the multitargeting build dimension (applicable only if the current build is a graph build). | TargetFramework |
InnerBuildPropertyValues |
Well-known | Specifies the property name that holds the possible values for the InnerBuildProperty (applicable only if the current build is a graph build). |
TargetFrameworks |
IsGraphBuild |
Well-known | True if this is a graph build; that is, the -graphBuild option is in effect. This option means that MSBuild constructs and builds a project graph. Constructing a graph involves identifying project references to form dependencies. Building that graph involves attempting to build project references prior to the projects that reference them, differing from traditional MSBuild scheduling. |
|
MSBuildAssemblyVersion |
Reserved | The version of MSBuild assemblies used to build the project. | 16.0 |
MSBuildBinPath |
Reserved | The absolute path of the folder where the MSBuild binaries that are currently being used are located (for example, C:\Windows\Microsoft.Net\Framework\<versionNumber>). This property is useful if you have to refer to files in the MSBuild directory. Do not include the final backslash on this property. |
C:\Program Files (x86)\Microsoft Visual Studio\2019\MSBuild\Current\Bin |
MSBuildDisableFeaturesFromVersion |
Reserved | Used by MSBuild and Microsoft SDKs to manage change waves. | |
MSBuildExtensionsPath |
Well-known | Introduced in the .NET Framework 4: there is no difference between the default values of MSBuildExtensionsPath and MSBuildExtensionsPath32. You can set the environment variable MSBUILDLEGACYEXTENSIONSPATH to a non-null value to enable the behavior of the default value of MSBuildExtensionsPath in earlier versions.In the .NET Framework 3.5 and earlier, the default value of MSBuildExtensionsPath points to the path of the MSBuild subfolder under the \Program Files\ or \Program Files (x86) folder, depending on the bitness of the current process. For example, for a 32-bit process on a 64-bit machine, this property points to the \Program Files (x86) folder. For a 64-bit process on a 64-bit machine, this property points to the \Program Files folder.Do not include the final backslash on this property. This location is a useful place to put custom target files. For example, your target files could be installed at \Program Files\MSBuild\MyFiles\Northwind.targets and then imported in project files by using this XML code: <Import Project="$(MSBuildExtensionsPath)\MyFiles\Northwind.targets"/> |
C:\Program Files (x86)\Microsoft Visual Studio\2019\MSBuild |
MSBuildExtensionsPath32 |
Well-known | The path of the MSBuild subfolder under the \Program Files or \Program Files (x86) folder.

See also MSBuildExtensionsPath and MSBuildExtensionsPath64.Do not include the final backslash on this property. |
C:\Program Files (x86)\Microsoft Visual Studio\2019\MSBuild |
MSBuildExtensionsPath64 |
