About Microsoft.CSharp.dll

Microsoft.CSharp.dll is a DLL file (Dynamic Link Library) used by Windows programs to share code and resources. It allows multiple applications to use the same functions, improving performance and reducing redundancy.

Overview

Microsoft.CSharp.dll is a dynamic link library (DLL) file associated with the Microsoft .NET Framework. The Microsoft .NET Framework is a comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.

This particular DLL, Microsoft.CSharp.dll, plays a pivotal role in supporting applications developed using the C# language on the .NET platform. C# is a modern, object-oriented programming language developed by Microsoft and is one of the primary languages developers use to create Windows applications, among other things.

The Microsoft.CSharp.dll provides functionalities that are essential for C# programs running on the .NET framework. It facilitates numerous dynamic features of the C# language, including late binding and dynamic type support, among others. By using dynamic features in C#, developers can create more flexible and adaptable applications, especially when interacting with other dynamic languages or COM objects.

For intermediate users troubleshooting issues related to .NET applications, any errors or problems involving Microsoft.CSharp.dll may indicate potential issues with C# dynamic features in the application or could be a sign of a corrupted or incomplete .NET Framework installation. In such cases, it might be helpful to ensure that the application and the .NET Framework are updated to the latest versions. If problems persist, reinstalling the .NET Framework or the problematic application may be a viable solution.

Fixes and Solutions

The first step in resolving DLL errors is to completely uninstall the affected software and reinstall its latest version. We know this does not always solve the problem, which is why DLLme exists. If reinstalling the application does not help, or if you are unsure which app is causing the error, follow the steps below. These are the most common solutions for fixing Microsoft.CSharp.dll errors.

  • Repair Windows: Make sure Windows is fully updated, then open Windows Terminal or PowerShell as an administrator (search for “PowerShell” in the Start menu, right-click it, and choose “Run as administrator”). This allows you to repair the Windows component store and run the System File Checker (SFC).

    Repair the Windows component store so SFC can pull clean files:

    DISM /Online /Cleanup-Image /RestoreHealth

    Scan all protected system files and automatically repair problems:

    sfc /scannow
  • Uninstall & Reinstall: On this DLL page, check the Company/Product section to identify the related app, then fully uninstall it. If you plan to continue using it, reinstall the latest version. Be sure to save or back up any important data before uninstalling. Windows or antivirus software may sometimes quarantine DLL files, especially if the DLL is unfamiliar or appears suspicious. Check your antivirus quarantine or logs to determine if this is the cause of your issue.
  • Download the DLL: Download the latest 32-bit or 64-bit version of the DLL directly from our repository using the download button above. Most users will need the 64-bit version, but if you are unsure, or if a 64-bit version is not available, you can install both the 32-bit and 64-bit DLLs. DLLme verifies DLLs that come from our admins, partners, and trusted affiliates. User-uploaded files may be verified later if a trusted source is confirmed.
  • Register the DLL: Most DLL files do not need registration, but some DLLs are COM components and must be registered to work correctly. If registration is required, open Windows Terminal or PowerShell as an administrator.

    Register the DLL (you can also drag the DLL file into the window to automatically fill in its full path):

    regsvr32 "C:\path\to\Microsoft.CSharp.dll"

    If you are registering a 32-bit DLL on 64-bit Windows, use the 32-bit RegSvr32:

    C:\Windows\SysWOW64\regsvr32 "C:\path\to\Microsoft.CSharp.dll"

    Or open Windows Terminal/PowerShell in the DLL’s folder and run:

    regsvr32 Microsoft.CSharp.dll

How to Install Microsoft.CSharp.dll

To install Microsoft.CSharp.dll, place the DLL file in the appropriate Windows system folder or in the same folder as the application’s .exe file. If you are not sure which version (32-bit or 64-bit) to use, you can safely install both.

On 64-bit versions of Windows, place 64-bit DLL files in:

C:\Windows\System32\Microsoft.CSharp.dll

Place 32-bit DLL files in:

C:\Windows\SysWOW64\Microsoft.CSharp.dll

Or place the DLL file next to the application’s .exe:

C:\path\to\exe\Microsoft.CSharp.dll
