I have tried to install dll from nuget (Could not find Microsoft.DiaSymReader.Native.x86.dll). but no luck.

Answer 1

Try deleting it

<PropertyGroup>
<Deterministic>true</Deterministic>
</PropertyGroup>

When the attribute of Deterministic is set to true, the DLL / EXE files generated by your program compilation will be determined. The HASH values of these files are the same no matter how many times they are regenerated. This is a great feature, but at the same time it can cause compilation errors.
