I've tried: deleting all bin/obj folders, cleaning, and rebuilding. Anyone else?

Hello Azeo

Yes, I have just had this issue.  Worked around by using the new method that allows you to specify individual Nuget packages for each control (or group of)

Individual NuGet Packages in Blazor - Syncfusion

This seems to work.  Had the same error as you when I did a straight upgrade using the existing method of referencing all Syncfusion Blazor controls in the one Nuget package.

Hope this helps.

Hi Azeo, 
 
We have Provided individual NuGet packages for our Syncfusion Blazor components. Please refer below link. 
 
 
We have checked your reported issue. We suspect that, you have use both Syncfusion.Blazor and individual packages in your application. So, you have use anyone packages install Syncfusion.Blazor or individual package. Please refer below code snippets. 
 
.csproj 
 
Syncfusion.Blazor – All component usage and its namespace. 
 
 
  <ItemGroup> 
    <PackageReference Include="Syncfusion.Blazor" Version="18.4.0.30" /> 
  </ItemGroup> 
 
 
                                                      OR 
 
individual packages - NuGet packages are segregated based on the component usage and its namespace. 
 
  <ItemGroup> 
    <PackageReference Include="Syncfusion.Blazor.DropDowns" Version="18.4.0.30" /> 
    <PackageReference Include="Syncfusion.Blazor.SplitButtons" Version="18.4.0.30" /> 
  </ItemGroup> 
 
For your reference, we have prepared a sample based on this. Please refer below link. 
 
 
If you still facing issue, please clear the cache for NuGet package. Please refer below link.

Thank you Ditchford and Mohan, using the individual packages worked.
Had issues with linking issues with bootstrap css, but this was the working solution:
Remove reference from .csproj file
Delete all nuget packages relating to syncfusion from .nuget
Deleted all bin/obj from affected referenced projects
Added individual components
Deleted using Syncfusion.Blazor references
