[SOLVED] Error while running the code after migrating

Error while running the code after migrating

I have an application in asp.net2.0 with C#. I have migrated my application in .NET 3.5 & I am receiving the below error.

Could not load file or assembly 'Microsoft.Build.Framework' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

Please let me know how I can solve this.

Thanks in advance.

Solution

in the web.config

in the assemblies place the right versions - or remove Microsoft.Build.Framework

<compilation ... >
      <assemblies>
...
      </assemblies>

Here is my assemblies for 3.5 project.

        <assemblies>
            <add assembly="System.Management, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A"/>

You can also create a new empty project and see what he makes on your web.config and by compare the new to the old, fix the old one by just keeping your values.
