You can produce binary logs from the dotnet build command by passing the -bl argument:

msbuild /bl

Binlogs from Visual Studio

⚠️ There are known limitations in binlogs obtained via the Project System Tools, so the use of Project System Tools is discouraged.

Replaying a .binlog to reconstruct text logs

You can pass a .binlog file to MSBuild instead of a project/solution to replay it to other loggers, as if a real build was happening. This allows you to reconstruct a text log of any verbosity given the .binlog file. Read more at: https://github.com/Microsoft/msbuild/wiki/Binary-Log#replaying-a-binary-log

Binary log advantages

Viewer Features

The MSBuild Structured Log Viewer can build projects and solutions or open existing log files:

Sensitive data redaction

Binlog is containing rich troubleshooting information, which can as well include some of the data, that users might not want to share with others (environment variables, local paths, secrets passed to tasks etc.) To allow sharing of such binlogs Viewer offers option to redact data from binlog under File -> Redact menu:

Note that the autodetection option is currently supporting only a very limited number of patterns (and even after future extensions it can only be considered best-efforts redaction - not an exhaustive one). So users are advised to pass the sesitive literals to be redacted explicitly to the redaction operation.

Command-line help for the /bl switch

See MSBuild command-line help msbuild /? for more information on the /bl switch. The switch is available starting with MSBuild 15.3 (Visual Studio 2017 Update 3 or newer).

Moviesda Padayappa Page

In the digital age, the name “Moviesda” has become a controversial watchword for millions of Tamil cinema enthusiasts. When paired with the iconic film Padayappa , the phrase “Moviesda Padayappa” encapsulates a stark paradox: the illegal distribution of a celebrated cultural artifact versus its enduring, almost mythical, status in Tamil popular culture. This essay explores how the piracy website Moviesda has inadvertently contributed to the immortality of Padayappa , while simultaneously posing a serious threat to the very industry that created it.

In a recent statement, Rajinikanth explained: “I did not give the rights to any telecast player, despite multiple requests. I wanted people to watch it only on the big screen. It should be a kondattam (celebration) for fans on my 50th year in cinema.” He believed the film's larger-than-life experience was meant to be shared in a theatre, not on a small screen. For decades, this has made Padayappa nearly impossible to access legally through digital means.

In today's streaming-driven era, it's almost unthinkable for a film of Padayappa 's stature to be unavailable on OTT platforms like Netflix, Prime Video, or Sun NXT. However, this absence is not an oversight but a deliberate and principled decision by Rajinikanth himself. moviesda padayappa

This is a fallacy. Intellectual property (IP) does not expire until 60 years after the death of the creator (under Indian law). Padayappa ’s rights are still active. Every illegal download deprives the current rights holder—often the film’s production company or the director’s estate—of legitimate income. Moreover, it devalues the work of hundreds of technicians, musicians, and artists. In the digital age, the name “Moviesda” has

In the history of Tamil cinema, few films command the monolithic reverence of Padayappa . Released in 1999 during the festive occasion of Tamil New Year, this K.S. Ravikumar directorial solidified Rajinikanth’s status as an industry demigod. Decades later, the film’s cultural footprint remains massive, surprisingly intersecting with modern digital search trends. Today, the phrase "Moviesda Padayappa" highlights how audiences continue to seek out this cinematic milestone in the digital age.

When users search for "moviesda padayappa," they are typically looking for: In a recent statement, Rajinikanth explained: “I did

Recording a binary log with older versions of MSBuild

The built-in /bl switch was only introduced in MSBuild 15.3 (Visual Studio 2017 Update 3). However there is a way to record a binary log with previous versions of MSBuild as well. You can attach the logger to any MSBuild-based build using the logger library targeting MSBuild 14: StructuredLogger.dll. It is available in a NuGet package:

msbuild solution.sln /t:Rebuild /v:diag /noconlog /logger:BinaryLogger,StructuredLogger.dll;1.binlog

Security Warning

The binary log contains and exposes all environment variables from the machine that the build ran on. If your environment variables contain secrets, they will be included in the .binlog file in plaintext.

Additionally, the source code of all project (.csproj) and targets files (.props, .targets, etc) is embedded in the .binlog file as well.

Some details from the file system (such as the name of the users folder) are visible as well.

However other source code (such as C# files) and files not related to the build are not included.

Before sharing binary log files please review the binary log file using the viewer to make sure there are no environment variables that should be kept private. Additionally check the embedded Files section to make sure that no secrets are stored in the .csproj files.

It is extremely important to be aware of these risks and it is recommended to treat the .binlog files like you treat your source code.

Reading MSBuild .binlogs programmatically

Reference the MSBuild.StructuredLogger NuGet package. All you need is to reference StructuredLogger.dll from that package.

There are various APIs for various scenarios. A high-level API to read a .binlog file into a tree structure that you normally see in the viewer is:

using System; using Microsoft.Build.Logging.StructuredLogger; class BinaryLogReadBuild { static void Main(string[] args) { string binLogFilePath = @"C:\temp\test.binlog"; var buildRoot = BinaryLog.ReadBuild(binLogFilePath); buildRoot.VisitAllChildren<CscTask>(c => Console.WriteLine(c.CommandLineArguments)); } }

There is a more formal API to read the C# compiler invocations from a binlog, read more here:

If you need a lower-level API to read the raw .binlog records yourself you can use BinLogReader.ReadRecords(string binLogFilePath):

using System; using Microsoft.Build.Framework; using Microsoft.Build.Logging; using Microsoft.Build.Logging.StructuredLogger; class BinLogReader { static void Main(string[] args) { string binLogFilePath = @"C:\temp\test.binlog"; var binLogReader = new BinLogReader(); foreach (var record in binLogReader.ReadRecords(binLogFilePath)) { var buildEventArgs = record.Args; // print command lines of all tool tasks such as Csc if (buildEventArgs is TaskCommandLineEventArgs taskCommandLine) { Console.WriteLine(taskCommandLine.CommandLine); } } } }

Another example of using the API is reading start/end times and durations of targets:
