Finding the right Microsoft System CLR Types for SQL Server 2012 WSUS download can save hours of deployment headaches—especially when offline updates are required.
Without the correct NuGet package version, your WSUS server might reject updates or leave CLR dependencies dangling. I’ve tracked down the exact 11.0.x.x packages that work, along with where to get them safely from Microsoft’s official sources.
How to download Microsoft System CLR Types for SQL Server 2012 WSUS via NuGet packages
Deploying SQL Server 2012 updates offline requires precise Microsoft System CLR Types packages—specifically version 11.0.x.x NuGet packages. Without the correct WSUS-compatible packages, installations fail with cryptic dependency errors.
I’ve spent years troubleshooting these issues and found the official Microsoft sources often bury the right files. Here’s how to locate and download them safely.
The key is using NuGet Package Manager with the correct package ID: Microsoft.SqlServer.Types. For SQL Server 2012, you need version 11.0.2100.60 or later, but not all versions support WSUS deployments. Always verify the package’s target framework matches your SQL Server 2012 installation (e.g., .NET Framework 4.0).
⚠️ WARNING: Downloading from unofficial sources risks corrupted or incompatible packages. Always use Microsoft’s official NuGet feed or the Microsoft Update Catalog.
Step-by-Step: Downloading Microsoft System CLR Types for SQL Server 2012 via NuGet
- Open Visual Studio or use NuGet Package Manager Console (run as admin).
- Run:
Install-Package Microsoft.SqlServer.Types -Version 11.0.2100.60to target the correct SQL Server 2012 version. - For offline installations, download the package manually from NuGet.org and save the .nupkg file.
- Use NuGet.exe to install locally:
NuGet.exe install Microsoft.SqlServer.Types -Version 11.0.2100.60 -OutputDirectory C:\SQLCLRPackages. - Verify the package contents include Microsoft.SqlServer.Types.dll (version 11.0.0.0 or higher).
Invoke-WebRequest -Uri "https://www.nuget.org/api/v2/package/Microsoft.SqlServer.Types/11.0.2100.60" -OutFile "C:\SQLCLR_Packages\Microsoft.SqlServer.Types.nupkg"
If you’re deploying via WSUS, ensure the package is approved in the WSUS console. Some organizations block NuGet downloads, so check your corporate proxy settings or use a local NuGet feed like ProGet or NuGet.Server.
I once spent a week debugging a WSUS deployment because the wrong CLR version was cached—always validate!
For SQL Server 2012 SP3 environments, use version 11.0.3000.0 of the package. This version includes critical fixes for CLR integration issues. Double-check the SQL Server Feature Pack on Microsoft’s site for additional dependencies like Microsoft.Data.Tools.Schema.Sql.
After downloading, test the package in a development environment first. Deploying directly to production without validation risks breaking CLR-dependent stored procedures. I recommend using SQL Server Data Tools (SSDT) to verify compatibility before rolling out to WSUS.
Need the package offline? Microsoft’s Update Catalog (https://www.catalog.update.microsoft.com) sometimes hosts older versions. Search for "Microsoft System CLR Types for SQL Server 2012" and filter by KB article (e.g., KB2679368 for SP1). Always download the full package, not just the DLL.
Finally, document your source versions and installation steps. WSUS deployments fail silently when package dependencies change. I keep a shareable checklist for my team—here’s a snippet:
☑️ Download Microsoft.SqlServer.Types 11.0.2100.60 from NuGet.org ☑️ Verify SQL Server 2012 SP2+ compatibility ☑️ Test in non-production first ☑️ Approve in WSUS console 🖥️
With these steps, you’ll avoid the common pitfalls I’ve seen—like mismatched versions or corrupted downloads—that derail offline SQL Server deployments. Happy updating! ⚡
Version-specific NuGet packages for SQL Server 2012 CLR Types: what you need to know
When deploying SQL Server 2012 updates offline, the Microsoft System CLR Types NuGet packages are non-negotiable dependencies. These packages enable CLR integration in SQL Server, but not all versions play nicely with WSUS deployments.
I’ve seen admins waste hours chasing the wrong package—here’s what you need to know to avoid that pitfall.
Microsoft releases these packages under the 11.0.x.x versioning scheme, but only specific builds (like 11.0.2100.60 or 11.0.3000.0) are guaranteed compatible with SQL Server 2012. Mixing versions can trigger CLR integration failures or silent corruption during WSUS syncs. Always verify the package’s target framework matches your SQL Server installation.
| NuGet Package Version | SQL Server Compatibility | WSUS Deployment Status | Key Notes |
|---|---|---|---|
| 11.0.2100.60 | SQL Server 2012 SP1 | ✅ Fully supported | Official WSUS catalog entry; includes fixes for CLR host crashes. |
| 11.0.3000.0 | SQL Server 2012 SP2 | ✅ Fully supported | Required for WSUS offline syncs; resolves assembly binding redirects. |
| 11.0.5058.0 | SQL Server 2012 SP3 | ⚠️ Conditional | Works but may require manual GAC registration in WSUS environments. |
| 12.0.x.x (or higher) | ❌ Incompatible | ❌ Breaks CLR | Targets SQL Server 2014+; causes version mismatch errors in 2012. |
Validating package integrity is critical. Use the NuGet Package Explorer to inspect the package’s lib\net40 folder—this ensures the correct CLR runtime is included. For WSUS deployments, I recommend downloading directly from the Microsoft Update Catalog (not NuGet.org) to guarantee digital signature verification.
One common pitfall? Assuming newer NuGet packages auto-upgrade older SQL Server versions. They don’t. Always check the package’s release notes for explicit SQL Server version support. For example, 11.0.3000.0 is SP2-only—using it on SP1 will fail silently until runtime.
Pro tip: If you’re deploying via WSUS, create a custom approval rule to block non-compatible packages. This saves hours of troubleshooting later. Always test in a non-production environment first—especially if mixing on-premises SQL Server with cloud-based WSUS.
