Could not load file or assembly 'Microsoft.AspNet.Web.Optimization.WebForms' or one of its dependencies. The...
I can't find anything to resolve this and have tried multiple things.
Task: I am trying to add bundles to an old existing web project. I have added everything I need I believe as I have done the same in a new project and it works.
<webopt:BundleReference runat="server" Path="~/bundles/masterstyle" />
This seems to be where the issue has started with this line above. I installed via nuget the web optimization webforms package which fixed the squiggly line under webopt. However, now, I am getting 2 issues.
BundleReference has a squiggly line saying "Element
'BundleReference' is not a known element/ This can occur if there is
a complication error in the Web site, or the web.config file is
missing".It also can't seem to find the package I have just installed which
is "Could not load file or assembly
'Microsoft.AspNet.Web.Optimization.WebForms' or one of its
dependencies. The system cannot find the file specified".
If anyone can help resolve this, it would be greatly appreciated. Been stuck on it for 4 hours now.
Here is the likely relevant stuff in my web.config file:
<pages>
<namespaces>
<add namespace="System.Web.Optimization"/>
</namespaces>
<tagMapping>
<add tagType="System.Web.UI.HtmlControls.HtmlForm" mappedTagType="we3.Site.Form" />
</tagMapping>
<controls>
<add assembly="Microsoft.AspNet.Web.Optimization.WebForms" namespace="Microsoft.AspNet.Web.Optimization.WebForms" tagPrefix="webopt"/>
</controls>
</pages>
<compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />

Install it from nugget: https://www.nuget.org/packages/Microsoft.AspNet.Web.Optimization.WebForms/
Install-Package Microsoft.AspNet.Web.Optimization.WebForms
Or you can manually download it from: https://www.nuget.org/api/v2/package/Microsoft.AspNet.Web.Optimization.WebForms/1.1.3
and add it as reference to your project (unzip first the .nupkg file)
Hi Sergui, It says 'Package 'Microsoft.AspNet.Web.Optimization.WebForms.1.1.3' already exists in project'. Also I can see the System.Web.Optimization.dll in the bin folder if that helps.

I can't see a references section of my project. It's a fairly old project I have taken over. I right clicked the project > add reference and I couldn't even find anything under optimization so it looks like I can't add it that way.

you should see something like this in solution explorer: imgur.com/a/PUq6nJm and there you should find a reference to Microsoft.AspNet.Web.Optimization.WebForms
– Sergiu Muresan

This is all I have for this project... imgur.com/a/Q1gLo8W further down the solution explorer are just basically aspx pages and then the config file. The second picture on that link is it all correctly working in a seperate project I have.
