Could not load file or assembly 'WebGrease' one of its dependencies. The located assembly's manifest definition does not match the assembly reference
I met this issue on a prod server, while everything worked fine on developer machine. These lines helped:
<configuration> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-1.5.2.0" newVersion="1.5.2.14234"/> </dependentAssembly> </assemblyBinding> </runtime></configuration>
Finally, the issue was in <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">. It caused the Render method to load wrong WebGrease assembly.
Removing the xmlns solved the issue for me.
I modified my web.config file so that the newVersion="1.0.0.0" matched my Referenced file version:
<dependentAssembly> <assemblyIdentity name="WebGrease" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-1.3.0.0" newVersion="1.0.0.0" /> </dependentAssembly>
