Hi Ambert,

I'm not sure how you ended up with that result. I was unable to reproduce that.

Your web.config does not look right. It contains multiple assembly redirects for the same assemblies and some other configuration is missing completely.

I tried to install Dynamicweb.Admin and got another runtime error which was related to the version of Microsoft.CodeDom.Providers.DotNetCompilerPlatform. This can be fixed by reinstalling that package after fixing web.config.

So try this...

1) Create a new empty Web Application project which targets .NET Framework 4.7.2

2) Use NuGet Package Manager Console to install Dynamicweb.Admin

Install-Package Dynamicweb.Admin -Version 9.7.5 –IncludePrerelease

3) Replace the contens of web.config with the contents of dynamicweb.web.config (no merge).

4) Use NuGet Package Manager Console to reinstall DotNetCompilerPlatform

Update-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform -Reinstall

This worked for me. Let me know if it works for you too.

Best regards,
Morten

The readme explicitly states to update the web.config, not replace the web.config, so get that me on the wrong foot

You need to update the web.config with the content of dynamicweb.web.config

However, it does work. But now its missing some DLL's.

Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Could not load file or assembly 'Microsoft.Build, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

What is your Visual Studio version?

Visual Studio Professional 2019

I don't know what could cause this. It looks like the package installation is incomplete or there is still something wrong with the web.config file.

The Microsoft.Build assembly should have been installed along with the RazorEngine.Roslyn 3.6.1-rc1 package and its dependencies.

Are there any errors reported in NuGet Package Manager Console during the intallation? 

When installing Dynamicweb.Admin one of the last lines in the console should be something like this:

Successfully installed 'Dynamicweb.Admin 9.7.5' to MyCustomWebApplication

Is your Visual Studio configured to use the nuget.org feed at https://api.nuget.org/v3/index.json and are you using that as source in the console?

Make sure that your Visual Studio is updated (Help > Check for Updates).

Best regards,

Morten

If it still doesn't work you can try to install Microsoft Build Tools 2015, reboot and create a fresh install after that.

Installation went fine, only when building I get a few warnings:

Updates VS2019 to the latest (from 16.4.1 to 16.4.3), still the same.

I tried adding the MSBuild references manually, but sadly to no avail. I'll probably try to make a new solution again, who knows it now magically appears ;-)

Redid everything, but sadly the exact same outcome.. The database installs, and then poof, msbuild error again :( I'll try to manually reinstall the msbuild tools.

Got it working!

I've downloaded a fresh copy of DW9, and copied the msbuild.*.dll files to the /bin in my solution.. Now it runs. Not the best way, but it works for now.. :)

Hi,

Just for reference - I am having the same issues.

I need to follow these steps after a fresh install:

Update-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform -Reinstall

Then I need to copy the roslyn folder from a downloaded application into the bin folder.

And then it works.
