In the world of .NET development, Microsoft.ReportViewer.Common version 9.0.0.0 is a legendary artifact from the late 2000s. It was the core engine for Visual Studio 2008 and SQL Server 2008 reporting, serving as the bridge that allowed developers to embed rich, interactive reports directly into Windows and Web applications. The Context: 2008 and the "Local Mode" Revolution
Before this version became a legacy headache, it was a breakthrough. Version 9.0 was the first to truly stabilize "Local Mode" (.rdlc files), which allowed reports to run entirely on the client’s machine without needing a full SQL Server Reporting Services (SSRS) instance. The "DLL Hell" Story
If you are looking for this specific version today, you’re likely living a classic developer "ghost story." Here is how the story usually goes:
The Legacy App: You inherit a mission-critical application built circa 2009.
The Crash: You move it to a new server, and it immediately fails with the dreaded error: "Could not load file or assembly 'Microsoft.ReportViewer.Common, Version=9.0.0.0...".
The Compatibility Trap: You try to upgrade to a newer version (like 10.0 or 15.0), but the old .rdlc report definitions refuse to open or break because version 9.0 used a specific XML schema that newer viewers often try to "auto-upgrade"—sometimes irreversibly. Official Download & Recovery
To fix this, you must install the Report Viewer Redistributable 2008 Service Pack 1. Microsoft still hosts the official installer, though it is now considered legacy software.
Official Installer: Download the Report Viewer Redistributable 2008 SP1 from the Microsoft Download Center.
Alternative (NuGet): For modern environments, you can sometimes find these older runtimes packaged on NuGet as Microsoft.ReportViewer.Runtime.Common, specifically version 9.0.21022.8. Pro-Tips for Modern Systems
To download and install Microsoft.ReportViewer.Common version 9.0.0.0, you need the Microsoft Report Viewer Redistributable 2008. This specific version is associated with Visual Studio 2008 and is required to run applications that display reports using Microsoft reporting technology. 1. Download the Redistributable
Because this is a legacy version (SQL Server 2008 era), it is no longer available via modern NuGet packages or the standard Visual Studio Extension manager.
Official Source: Historically, this was available through the Microsoft Download Center. If the direct landing page for the "2008 Redistributable" is retired, it is often bundled with the SQL Server 2008 R2 Reporting Services or Visual Studio 2008 installation media.
Alternative: You can often find the standalone installer named ReportViewer.exe on reputable mirror sites or archived Microsoft support pages. 2. Installation Steps Run the ReportViewer.exe installer.
Follow the setup wizard to install the required assemblies to your Global Assembly Cache (GAC).
Once installed, the file Microsoft.ReportViewer.Common.dll (version 9.0.0.0) will typically be located in:C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\9.0.0.0__b03f5f7f11d50a3a\ 3. Adding the Reference to Your Project
If you are developing an application that requires this specific version: Open Visual Studio: Go to your project's References.
Browse: If it doesn't appear in the .NET tab, browse to the installation folder or the GAC path mentioned above.
Toolbox: If you need the visual control, right-click the Toolbox, select Choose Items, and filter for Microsoft.ReportViewer.WinForms or WebForms version 9.0.0.0. Important Note on Compatibility
Version 9.0.0.0 is very old. If you are using Visual Studio 2015, 2017, 2019, or 2022, it is highly recommended to use the latest version available via the Microsoft RDLC Report Designer extension or the Microsoft.ReportingServices.ReportViewerControl NuGet package to avoid compatibility issues with modern .NET frameworks. microsoft.reportviewer.common version 9.0.0.0 download

It sounds like you're looking for a specific version (9.0.0.0) of Microsoft.ReportViewer.Common, likely to resolve a dependency or compatibility issue in an older .NET project.
Here is the long story — and the practical solution — regarding that specific version.
For applications targeting .NET Framework 4.0 or earlier, or for Visual Studio 2010 projects, you might need to manually ensure that the correct version of Report Viewer is referenced.
For .NET Framework 4.5 and later:
If your project targets .NET Framework 4.5 or later, you can use the Report Viewer control from the Visual Studio toolbox or install it via NuGet Package Manager. However, for .NET Core or .NET 5/6+, consider using the Microsoft.ReportingServices.ReportViewerControl.Web NuGet package.
Direct Download:
For specific versions like 9.0.0.0, which corresponds to Report Viewer 2010:
From Microsoft Visual Studio: Ensure Visual Studio 2010 is installed. The Report Viewer control is typically available within Visual Studio. You can add it to your project via the Toolbox.
From NuGet (for compatibility): Sometimes, direct installation through NuGet can manage versions and dependencies better. However, the original Report Viewer 2010 (version 9.0.0.0) might not be directly available on NuGet for newer .NET targets due to its age and compatibility.
If you are manually moving the files, Microsoft.ReportViewer.Common usually requires the following supporting files to function correctly:
Microsoft.ReportViewer.WinForms.dll (or WebForms.dll)Microsoft.ReportViewer.ProcessingObjectModel.dllThe process to work with Microsoft.ReportViewer.Common version 9.0.0.0 involves checking compatibility with your .NET Framework target, potentially installing Report Viewer through Visual Studio, or manually adding references. Always refer to the most recent Microsoft documentation for support and updates.
Microsoft later pushed some legacy versions to NuGet. You can try:
Install-Package Microsoft.ReportViewer.Common -Version 9.0.0.0
Note: This package may be unlisted or deprecated. If it fails, use the redistributable installer.
Full error: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration.
Fix: Add the following to your app.config or web.config:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" />
</startup>
